Cotton-top Tamarin
Other names: cotton-headed tamarin or white-plumed bare-face tamarin; paryk-pinché (Danish); gewone pincheaap (Dutch); valkotöyhtötamariini (Finnish); tamarin d'Oedipe, tamarin à perruque, or tamarin pinché (French); lisztäffchen (German); bichichi, mono tití cabeciblanco, tití, titis, tití blanco, tití leoncito, or tití pielroja (Spanish); bomullshuvudtamarin or pinché (Swedish)
MORPHOLOGY
These New World monkeys are small-bodied and easily recognized by the characteristic fan of long, white hair on their heads. They have very fine hair on their black-skinned faces such that their faces appear naked. Tamarins are characterized by their facial appearances and are divided into three groups: the hairy-face, mottled-face, and bare-face groups. Cotton-top tamarins are categorized in the bare-face group (Garber 1993). They have mottled gray-brown shoulders, back, and rump while their stomach and limbs are white. They have reddish-brown hair on the back of their thighs and base of their tail but the rest of the tail is gray-brown-black (Rowe 1996; Groves 2001). Cotton-top tamarins are not sexually dimorphic and the average height of both males and females is 232 mm (9.13 in) (Rowe 1996). Wild males and females weigh between 410 and 450 g (14.5 and 15.9 oz) but average 416.5 g (14.7 oz), while captive cotton-top tamarins are significantly heavier and weigh, on average, 565.7 g (19.9 oz) (Savage 1990).

The most common modes of locomotion for cotton-top tamarins include quadrupedal running, bounding, or galloping along medium to small branches as well as clinging and leaping between trees on thin or small branches (Rowe 1996; Kinzey 1997). Members of the subfamily Callitrichinae have claw-like nails (called tegulae) that resemble a squirrel's rather than the flat nails (called ungulae) characteristic of other primates, including humans. These claw-like nails aid in clinging, running, and leaping through trees (Kinzey 1997). Cotton-top tamarins also exhibit the trait of primarily giving birth to non-identical twins, as is seen in other callitrichines (Rowe 1996).
Cotton-top tamarins live for an average of 13.5 years, but the oldest recorded cotton-top tamarin lived to be 24 years old in captivity (Rowe 1996; Savage pers. comm.).
RANGE
CURRENT RANGE MAPS (IUCN REDLIST):
Saguinus oedipus
Cotton-top tamarins are one of three Amazonian species of tamarin and are found in a small area of northwest Colombia in a range bound by the Cauca and Magdalena Rivers and the Atlantic coast (Snowdon & Soini 1988; Groves 2001). Though the overall area bound to the north by the Magdalena River and the west by the Cauca River has historically been suitable habitat for cotton-top tamarins, they are now only found in fragmented parks and reserves throughout this area. One of the strongholds of the remaining cotton-top tamarins is in Paramillo National Park, a 540 km² (208 mi²) park containing primary and secondary forest (Mast et al. 1993).
One of the only long-term studies of wild cotton-top tamarins was started in the mid-1970s by primatologist Patricia Neyman. Not only did she habituate wild groups but she also live-trapped and marked them, allowing for qualitative research on group membership changes and life history characteristics of individual animals (Neyman 1977). More recently, Anne Savage and her colleagues began working on a long-term research and conservation project in La Reserva Forestal Protectora Serranía de Coraza-Montes de Marìa in Colombia, another principal refuge for cotton-top tamarins (Savage et al. 1996a).
It is estimated that there are between 300 and 1000 cotton-top tamarins left in Colombia (Savage 1990). There are 1800 cotton-top tamarins in captivity and of those, 64% are found in research laboratories (Savage et al. 1997a).
HABITAT
Cotton-top tamarins are found in humid tropical forest, dry deciduous forest, and secondary growth forest (Hernández-Camacho & Cooper 1976; Snowdon & Soini 1988; Mast et al. 1993; Kinzey 1997). Tropical forests have multiple vertical layers of growth, from the short understory (less than 5 meters) to the tallest trees in the canopy (over 20 meters). Cotton-top tamarins use multiple layers of the tropical forests in which they are found, moving vertically between the understory and canopy, but preferentially utilizing the lower vertical levels of the forest. They are most commonly found in trees but can be seen on the ground, foraging among leaf litter (Snowdon & Soini 1988). These tamarins are also highly adaptable to secondary or remnant forest fringes or patches and can live in relatively disturbed habitats. They are found primarily at elevations below 1500 m (4921 ft), but rarely above 400 m (1312 ft) (Hernández-Camacho & Cooper 1976).
In the deciduous or dry forest parts of their range, rainfall is highly seasonal, with the dry season lasting from December to April and heavy rainfall from August to November. Annual average rainfall varies between 500 and 1000 mm (1.64 and 3.28 ft) and there are periods when the forest floor is flooded (Neyman 1977). In the humid rainforest where they are found, annual rainfall can be as high as 1300 mm (4.27 ft) (Mast et al. 1993).
ECOLOGY

The primary components of cotton-top tamarin diet are insects, fruit, plant exudates, and nectar, but they have also been recorded eating reptiles and amphibians. It is important for tamarins to have a high-quality, high-energy diet because of their small-body size, limited gut volume, and rapid rate of food passage (Garber 1993). The role of plant exudates in the diet of callitrichines is important as a source of minerals, water, and other nutrients though tamarins do not have the same specialized adaptations to feeding on gum, sap, resin, and latex as do marmosets (Callithrix species) and are therefore primarily dependent on insects and fruits (Snowdon & Soini 1988; Kinzey 1997). When they do eat gum, cotton-top tamarins rely on more indirect means to obtain exudates than their marmoset (Callithrix species) counterparts; they depend on natural weathering of bark, the holes left by wood-boring insects or rodents, and re-gouging of hardened gum holes to stimulate flow (Snowdon & Soini 1988; Kinzey 1997). Insectivory is also important in their ecology. Some insect-hunting techniques employed by cotton-top tamarins include stealth, turning over leaves, exploring crevices, pouncing, and moving rapidly to the ground to seize prey. Like foraging for other foods, hunting for insects is an individualistic behavior (Garber 1993). Foraging occurs in the middle layer of the canopy from five to 15 m (16 to 49 ft), and while cotton-top tamarins select a feeding site because of its fruit availability, they also hunt for insects and utilize gum in the vicinity (Neyman 1977). Cotton-top tamarins clearly compete for access to some foods with squirrels, other diurnal primate species, and various birds. They also may be competing for access to food resources with nocturnal fruit and insect-eating species including bats (Neyman 1977).
Tamarins are highly important seed dispersers in tropical ecosystems. They ingest and void seeds larger than those consumed by much larger species of primates, including chimpanzees (Pan troglodytes and Pan paniscus), baboons (Papio species), and macaques (Macaca species). Voided seeds show high germination success compared to others, but there may be another benefit to this seed-swallowing behavior (Snowdon & Soini 1988; Garber 1993; Sussman 2000). One function of swallowing such disproportionately large seeds may be to mechanically expel intestinal parasites from their digestive tract. Certain worms, caused by consuming orthopteran prey, attach to the lining of the gut and cause inflammation, lesions, and death. By swallowing and expelling seeds, these may, as they work their way through the gastrointestinal tract, dislodge intestinal parasites (Sussman 2000).
The typical daily routine of cotton-tops involves an alternating pattern of foraging, resting, and traveling. They sleep in a group and start their day about an hour and 20 minutes after dawn when the entire party leaves the sleeping tree at the same time. Cotton-top tamarins follow established routes to find available foods, moving between .12 and .24 (.07 and .15 mi) per hour and covering about 1.5 and 1.9 km (.93 and 1.18 mi) per day over home ranges of between .078 and .10 km² (.03 and .04 mi²) (Neyman 1977). After about an hour of foraging, they begin to rest for a few minutes at a time, either stretching out on a branch or grooming within the social group. They continue to travel and forage throughout the day, taking increasingly longer resting periods, the longest being around midday. In late afternoon, they begin to travel more quickly and more cohesively with limited foraging stops until they reach a sleeping tree (Neyman 1977). Cotton-top tamarins prefer to sleep in trees with some foliage cover such as broad leaves, vines, epiphytes, or lianas. They repeatedly use trees within their home range for sleeping sites, but do not generally use the same tree on consecutive nights (Savage 1990). By selectively choosing sleeping trees, getting a relatively late start to their day compared to other primates, and hastening foraging and traveling speed before dusk, cotton-top tamarins may be avoiding many crepuscular and nocturnal predators. Some of the main predators of cotton-top tamarins include raptors, mustelids, felids, and snakes (Snowdon & Soini 1988; Sussman 2000). Cotton-top tamarins are extremely vigilant, constantly scanning for potential predators above and around them and even in captivity can be observed stopping their activities to look around (Price 1992). In the wild, when the group rests during the day, one group member separates itself from the resting animals and remains vigilant, alarming the group through vocalizations if it detects danger (Savage 1990).

Meerkats are born with hair but not full coats and with their eyes closed. They will live in the wild up to 10 years. However, in captivity they can live to be 15 years of age. Although they are relatively healthy animals, they are unfortunately prone to bovine tuberculosis and have been known to get rabies. When they are adults at about one year of age they will weigh around 2 pounds (750 - 820 grams) and stand an average of 12 inches high (30 centimeters). When they are on all four of their feet their height is only 6 inches (15 centimeters). Like all mongooses, they are agile hunters; however, they differ considerably from most of their other relatives. Unlike the typical mongoose of which there are around 35 types, Meerkats live in communities and depend on one another for survival. There are three other types of sociable mongooses, the Banded, the Kousi Mansi and the Dwarf mongooses. They also live in groups, but are not usually found in the Kalahari desert. While most mongooses are nocturnal, Meerkats hunt during the day. They live at night in burrows, which are complex tunnel systems consisting of mounds, access holes, and tunnels which lead to numerous sleeping chambers. A Meerkat community is called a mob or gang, and can number up to 40. There is always a dominate alpha male and dominate alpha female in each gang. The Meerkats larger mongoose relatives typically live alone or in pairs. These intelligent animals are extremely communicative and posses a large vocabulary. They flourish in their environment and are not endangered.
Meerkats live in southern part of Africa which is dominated by the Kalahari desert - The Kalahari spreads over the countries of South Africa, Namibia, Angola, Botswana, and Zimbabwe. The Kalahari desert has little rainfall and an arid climate with open plains. It spreads across the Southern part of Africa covering over one million square miles and is 10 times the size of Great Britain. The land is covered by a porous or soft sand that in many places is bright orange in color. The temperature in the summer months of October to April can reach 115 (f) or around 40 (c) which can give a sand temperature of 158 (f) or 70(c). In this harsh environment the difference between being in the sun and shade can be up to 86 (f) or 30 (c). The winter months from May to September are very different from the summer, you will see highs around 70 (f) or 22 (c) during the short days and lows at night down to 14 (f) or -10 (c). Winter is the dry season.
The average rainfall is 12 inches (300 millimeters) which comes between January and April. This is towards the end of the summer. There is little surface water but there is quite a bit of moisture below the sand. Generally, the broad plains of the Kalahari are covered with a thin coat of different types of grass and thorn scrub. When it rains during the summer, which is rare, the desert transforms into a lush carpet of plants, grasses, and flowers.
The Kalahari consists of both soft and compacted sands, ranging in color from bright orange to white. Meerkats like the soft sand when digging for food as it lessons the energy requirements in this harsh environment. However, they prefer compact sand to build their burrows which would collapse in softer sands. There could be any number of reasons Meerkats flourish in this environment, though all relate to competition for food and predators. One could speculate that the Meerkat may be a weaker type of mongoose that would find competing for food with other mongooses a tremendous hardship or that their coats would stand out making them easy prey for others. What is known is that Meerkats have specially adapted to the Kalahari, which is described later. The Yellow and the Slender mongooses also live in the Kalahari but generally live in harmony with the Meerkats. This is primarily because they each have a different diet and are not in competition for food. Unfortunately the Yellow mongoose will sometimes eat a Meerkat pup (baby), so meerkats will keep their distance from Yellows when there are pups around. Many other animals have also adapted over time in order to survive in this harsh environment, making the Kalahari a remarkable and interesting place. Even within this barren and harsh environment, animals and plant life flourish.
Animals in the Kalahari have a 40% lower metabolic rate then their counterparts in other parts of the world. This adaptation allows animals to survive with less food and water. Of course,the Kalahari's intense heat puts animals at risk of overheating, making the ability to efficiently regulate body temperature a necessity. Body size is key, the smaller the animal the faster the loss and gain of body heat. The "mouse-to-elephant curve" measures this relationship. The general idea is as follows, a gerbil has a 50 times higher metabolic rate than a elephant (per gram of bodyweight); therefore, the amount of energy from food that the gerbil needs to maintain its body temperature is greater than the elephants, making the need for food gathering almost constant. The Meerkat looses 5% of its body weight over night making the search for food very important every day. Can you imagine losing 5% of your body weight over night ? They can also get their fluid requirements from what they eat, so water sources while not a neccessity are helpful.

Meerkat characteristics - Meerkats at adulthood will grow to a standing height of 12 inches (30 centimeters) and weigh around 2 lbs. (750-820 grams). A pregnant female will weigh around 2.8 lb. (1.1 kilos). Their legs are short and their bodies are long and thin. Their tails are also long and thin with a dark tip. The reason for the dark tip is to identify other gang members while foraging for food. Meerkats forage for food with their tails in an upright position enabling them to easily identify their fellow gang members. Meerkats reach sexual maturity at 10 months and adulthood at 11 months. Both males and females share similar physical traits such as short hair and gray or tan markings. The markings on their backs are unique and no two are the same. They have dark brown or black bands around their eyes. Their ears are tipped with black or dark brown. They have dark bands on their sides and back. Their faces and throat are predominately a shade of white. There are four digits on each foot with very sharp non-retractile claws which are curved. They use their claws to dig their burrows. Meerkats also have the unique ability to close their ears, this is to keep dirt out while they burrow, which they do quite often.
Meerkats fur ranges in color from silver to orange to brown. Much of this depends on the subspecies as well as the sand color in which they live.Even in close proximity in the Kalahari you will find Meerkats with tanish fur in the dried out riverbeds and orange fur in the dunes above. Their coats have a great ability to act as both an insulation to keep heat in and an exhaust system to prevent them from overheating in the harsh climate. In the winter they will spread their hair out so to create a heat insulation effect much like a wet suit. Their stomach acts as a sort of solar panel during the winter months. Under a thin layer of stomach hair is a patch of dark skin which collects heat from the winter sun in order to provide warmth on cool days.
Meerkats vision is outstanding. They have a dark band around their eyes, which reduces any glare from the sun. As a result, Meerkats have the ability to see a predatory bird as they look directly into the sun. A Meerkat removes sand from its eyes by blinking. Between the eye and eye lid there is a white membrane called the nictitating membrane. This membrane acts as a windshield wiper and removes sand from their eyes with every blink. However, their ability to see things close up is not as good. Furthermore, they seem to have a problem with depth perception, not being able to focus within 20 feet (6 meters) of themselves. Often they will bob their head up and down trying to get the perspective right. As a result of this nearsightedness, they will often miss food directly in front of them. They often depend on their sense of smell to find food.

Meerkat cuisine .- Agile Meerkats always forage for their food in groups but catch and eat their food alone as their diet usually consist of small portions. As they search for their food they spread apart from one another on the desert floor. This distance between foraging Meerkats averages from 6 feet (2 meters) to 45 feet (15 meters), but can extend to 150 feet (50meters). The distance often depends on the availability of food. Generally Meerkats stay at their burrow one or two nights, so there line of foraging is usually from one burrow system to the next. During the winter when there is no grass and food is sparse they have been seen being as far as 150 feet (50 meters) apart. In the late summer when desert grass may reach three feet high and food is abundant they will forage about 6 feet (2 meters) apart. Meerkats frequently communicate with each other while they are looking for food in order to warn of possible dangers in the area or hear a distress call if one gets lost. Usually there is a Meerkat acting as a sentry watching for danger as the others look for food. This is usually the one that is the best fed at the time, there is no evidence that either sex has a predominance for sentry duty. If trouble arises, an alarm is sounded by the sentry and the gang will band together in a mob ( a mob is when Meerkats band together to fight) to assess what the danger is, and take appropriate defense actions. Meerkats will sometimes collect food for their pups and babysitters back at the den. The young pups as they learn to search for food will follow the adults to help supplement their diet. Current studies show that the pup that gives the loudest begging call gets the most food from the adults.
Most of the Meerkats food is found underground and their specially adapted bodies are perfect for this. Their front claws are curved and act as shovels. They often have to dig their own body weight in dirt just to get a small insect. Foraging for a Meerkat means digging here and there and occasionally finding a tasty morsel on the surface then moving forward with the gang on the endless search for food. A typical Meerkats diet consists of worms, crickets, grasshoppers, small rodents, lizards, small snakes, birds, eggs, fruit, and ant larvae (which they especially love). Insects are a particularly good source of nutrition for the Meerkats because they reproduce rapidly and supply an almost constant food source. I have even had the rare chance to see a Meerkat find a Kalahari truffle which is rare and very expensive in stores. He seemed to enjoy it immensely. Meerkats also love to eat poisonous scorpions which are plentiful. They do this by quickly biting off their stingers and then consuming the rest. Meerkats appear to be resistant to many deadly venom's which greatly increases the variety of their diet. A Meerkat will often drag any poisonous prey such as a scorpion or millipede across the sand before eating it. They do this to remove the chemical defenses of their soon to be meal. They will make use of a water source if one is nearby but Meerkats have developed the ability to get all their liquid requirements from their diet. In the summer, the Meerkats must work harder to get their food because the insects have burrowed deeper in the sand in order to be closer to moisture. The rain brings the insects back to the surface, which means feast to the Meerkat.
The Meerkat home - As mentioned previously, the Meerkats live in underground burrows which consist of entrance holes, tunnels, and sleeping chambers. There may be up to 70 different entrances to the burrow system which may also serve as an exit if the Meerkat is inside the burrow system. They are territorial and maintain an area of about one to three square miles. Their territorial expansion depends on the size of the gang, as well as, the abundance of food and water in the area. Meerkats mark their territory with the use of their anal gland or saliva from their cheek. This marking is done by the alpha male of the gang. They will protect their boundaries ferociously against other gangs. They have from 6 to 15 dens in their territory and will move dens every day or two. The breeding burrow ,which is where the offspring are born, is an exception to the frequent moves. Meerkats will stay at a breeding burrow for about three weeks. It is at this time that the young are able leave the burrow and start to learn to forage for food with the adults. In addition to this, the parasite loads become heavy in the burrow and fill with ticks, fleas and other undesirables after three weeks. Breeding burrows differ from other burrows in that they will have higher mounds of sand around the entrance holes. This is a result of the continual renovation of the tunnels and sleeping chambers necessary for the longer stays. The mounds of dirt around the entrances can reach up to three feet high. When breeding is successful Meerkats often return to the same breeding burrows to have there young. As the Meerkats rotate burrows, the insect population of each abandoned burrow has the opportunity to multiply. Furthermore, the burrow system itself needs to regenerate while the feces left behind becomes food for other animals and the parasite load decreases. When dens are not being used, snakes and ground squirrels often find them to be convenient residences. Mixed everywhere in the Meerkat territory are bolt holes. A bolt hole is a small system of entrances and tunnels between burrows. These bolt holes give Meerkats a place to take cover if danger arises if they are out foraging.
The strategic reasoning behind such an elaborate construction of multiple entrances, is to provide many alternative exits if a dangerous intruder should invade their home. Likewise they have multiple entrances in the burrow if the danger is from the outside. They sleep in groups, cuddled up or on top of each other for warmth as they are particularly sensitive to the cold. In the summer they tend to space out when they sleep. Their sleeping chambers are usually 6 to 8 feet under ground. This keeps the temperature in the sleeping chamber at a more constant level, cooler in the summer and warmer in the winter. There are several sleeping chambers in the den but they will only use one at a time, in the breeding burrows there will be more sleeping chambers. They will move sleeping chamber because of build up of contaminates. What may seem odd to you is, Meerkats will urinate in their dens. This could be for several reasons first it may aid in a marking system to one another. Second Meerkats don't survive well alone so to go outside at night to go to the bathroom is not a prudent thing. In captivity though Meerkats can be trained to go to the bathroom in a litter box. There are certain beetles that share their den that they don't eat. These insects will eat their deification. Above the tunnel system, there is usually a dirt mound resulting from all of their excavation. This higher vantage point serves as a lookout point for the small Meerkats. From this outpost of sorts, they can survey the terrain for predators. This done in the the morning before they leave the burrow for foraging and in the evening before they go to bed.
Other animals, such as squirrels or the yellow mongoose, sometimes share the Meerkats burrow. Because these animals do not compete with the Meerkats for food, they are allowed to share the den. When pup are born they will keep the yellow mongoose away because they will eat a Meerkat pup. Predators, such as cobras, are not welcome houseguests. Meerkats will purposely harass a cobra in the open so to discourage it from entering the den.
Meerkats sometimes move their territories when food becomes to sparse or when another gang of Meerkats forces them from their previous den. Often territories overlap one another and a stronger Meerkat gang will overtake a weaker gangs burrow system. This forces the weaker gang to take the loss and try to expand in another direction, or wait tell they are stronger and retake the lost burrow system.

Mating and reproduction - Meerkats try, but do not usually mate for life. Mating in the gang is suppose to be reserved for the alpha male and alpha female, but things happen to change this. First the alpha male might die or be overthrown by another male from inside their gang or another gang. Or the alpha female might mate with a male from a wondering male from another gang while out foraging for food, the alpha male never knowing. What they won't do is mate with another direct family member. When the dominate female is ready to breed she will chase away all the other beta families that can bear children, this will be females at 10 months and older. The temporary outcast will follow the gang until the alpha female has had her pups (babies) and regains her strength. This is done because she wants only her offspring in the gang and another beta female might try and displace her during her weakened time of giving birth. The trailing females often get impregnated from males from other gangs they encounter. Often they will abort these births. If the do give birth they will attempt to sneak them in with the pups of the alpha female. The alpha female will if she notices kill and eat the beta females babies. The beta female have about a 20% chance of getting the young snack in with the alphas females pups. A interesting note, if the alpha female pup die, no other meerkat will eat them. A few days after the birth of the alphas pups, the once outlasted females will rejoin the gang and help with the giving milk to the new pups if they are able. It was once observed that a beta female killed the alpha females pups just after birth and replace them with her pups a few days later, the alpha female not knowing the difference. They can breed every two months but tend to successfully breed two to three times a year depending on food availability. There was one gang observed breeding four times in a year. The gestational period is 70 days resulting in a litter of usually five to six. The pregnant female will increase her body weigh approximately 40% gestation (see - Meerkats are a type of mongoose). The babies, called pups, are born with sparse fur and eyes closed. For the first two weeks they stay in the sleeping chamber and drink their mothers or milk producing females. The third week they will venture outside and stay around the burrow system with a babysitter. . During this period when the alpha female is not feeding the young, babysitters will watch the pups while the alpha female goes out to feed, fortifying her supply of milk and her strength. She will do less sentry duty at this time and never babysitting. From week 4 to week 6 the pups will forage with their elders getting nourishment from both milk and insects. At 6 weeks to 16 weeks they will find their own food as well as be supplemented by the elders, and no longer getting milk. Studies show that the pups that make the loudest begging calls get fed the most from the elders. After sixteen weeks they are on there own to find there food Each pup will be taken on by a adult Meerkat which will act as a mentor, who will take the responsibility to teach the pup necessary skills for foraging for food as well as responding to danger. Male Meerkats tend to mentor male pups and female Meerkats tend to mentor the female pups. Many of skills Meerkats have are taught by the mentors rather then being instinctual.
Meerkats reach sexual maturity at 10 months, and reach adulthood at 11 months. After 10 months a Meerkat may venture out of the gang looking for breeding opportunities. They may also leave to form new gangs or join other gangs. They also may stay with their original gang for up to three years before venturing out. They also may leave in groups of two or three. It takes a brave Meerkat to leave the gang because the road out if filled with many dangers for the sole are small group.
Typical day of a Meerkat - Meerkats are extremely social animals. Observing Meerkats is a wonderful experience. They love grooming one another, wrestling and playing with one other. They have avid curiosities and can make a toy of almost anything. Even with all this play, Meerkats do not ignore the need for security. One Meerkat always seems to be a sentry and stands guard to keep the gang safe.
There typical day consist of, they wake up early in the morning as the first rays of sun stretch across the Kalahari. The first to come out of the burrow is usually the last one in from the preceding night. This Meerkat surveys the area to make sure the coast is clear after that the others start to rise one by one from several entrances. They start by soaking up the sun to warm up there bodies from the nights sleep by facing the sun and using their stomachs as solar panels.. One may observe some digging around the entrances, this seems to be more like exercise to warm their bodies up. Then the young start to scurry around play and grooming one another, as the elders spend time grooming sunning. Once hunger starts to set in, the search for food is on. The alpha male sets the direction for the day and decide weather or not to move towards another burrow system.. Scurrying hear and there and digging here and there, but always one is on sentry. As the day goes on and the heat sets in they will stop for a rest. These rest periods are longer during the summers but so are the days. As the day cools they are off again in the afternoon in search of food. Just before sunset they will arrive at the den for the night. At this time they will commence on repairs of the den as well as well deserved grooming and giving one another affection which is really marking one another with the anal gland or cheek saliva. As the sun falls, they descend one by one into the burrow for sleep all huddled together. Lastly, they don't like the rain and will stay in their burrow and not forage for food until the rain stops.
Interestingly enough Meerkats seem to identify one another my smell rather than sight. That is why the are constantly marking one another. For instance if a Meerkat gets separated for some time and try to rejoin the gang, the gang will think it is a intruder and get in a mobbing defense stance ( mobbing is when they huddle together so to look bigger and present aggressive behavior) until they smell what they think is the unknown Meerkat. Once the sent is recognized everything is fine.

Meerkats social structure - To survive, Meerkats must live in groups for protection, as the desert presents many challenges. Each Meerkat has an important, role to perform. It was first thought Meerkats had well defined roles in their gang from being a sentry to baby sitting to foraging for food for the young. Recent studies have disprove this and actually show that hormonal changes in Meerkats influence their behavior. Also the conditions around the burrow system effect their responsibilities. When food and water is abundant more time is spent being sentries, renovating the burrow systems, relaxing and caring for the young. Some things are instinctual while others are taught to the pups by the elders. For example raising young is a learned behavior for Meerkats. If a pup is separated at birth and kept as a pet, and the pup gets pregnant. She will not know how to raise her young or teach them how to forage for food. Meerkat roles vary:
alpha male - Dominate male of the gang, has breeding rights to the alpha female. The dominate male is not necessarily decided by the largest male in the gang.
alpha female - Dominate female of the gang, all betas are subservient to her. Only one that is suppose to breed in the gang.
beta male - Subservient males will leave the gang by 3 years in search of better breeding opportunities. They are 10 months or older
beta female - Subservient females will support the alpha Meerkats. They will be driven temporally from the gang by the alpha female when she is ready to get pregnant. They will leave the gang by 3 years in search of better breeding opportunities. At 10 months or older they are at sexual maturity.
pups - Meerkat babies, 10 months or younger.
babysitter - Stays with the pups while the gang is out foraging for food. Different gang members take the responsibility different days, this is not domiated by males of females. Generally though the least hungry Meerkat will do the babysitting. The alpha female never baby-sits. This duty is for Meerkats 6 months or older.
sentry - Watches over the gang to spot danger. It is either done standing on the ground or climbing a tree or bush. Known to climb up to 30 feet in a tree to do sentry duty. This duty is not dominated by males or female. There is a sentry on watch both at the burrow system as well as when the gang is foraging for food. During times of less available food less sentry duty is done when searching for food.
excavating - Necessary to renovate burrow systems. Often Meerkats will get one behind another and work together to move sand out of the burrow system. Like how firemen would hand buckets of water to one another to put out a fire in the old days.
mentoring - A elder Meerkat will take on the responsibility of teach a pup the do's and do don'ts of being a Meerkat. This includes how to raise young, how to forage for food, and what dangers lurk about.
grooming - Meerkats like to groom one another, and in fact have a natural reflex to groom when the area where there back and tail meet is stimulated. They will remove ticks and fleas from one anther and actually eat them, though these parasites are not a normal part of the diet
play fighting - Often done by the young in the morning and to a lesser degree in the evening. Adults will also play fight. This teaches the young to fight as well puts a dominance order to the gang.
Beta males and famales often leave the gang by three years to live with different gangs or join together to form different gangs in order to increase their chances to breed. Meerkats that embark on this journey alone or in groups of two or three face great danger, as Meerkats are most vulnerable when they few in number. Sometimes Meerkats will ally themselves with one another and takeover another gang, and getting rid of the competitive alpha male and perhaps the alpha female.
The size and makeup of the meerkat community determines what duties each will have. There is usually a dominate male and female in the community although there also seems to be a second in command. I have seen a case where the alpha female was killed and the alpha male did not seem to know what to do. He had not taken on another alpha female because that would mean a female from the outside. It was felt he would at some point leave the gang in search of throwing out another alpha male from a rival gang. The alpha male is responsible for marking the territory, some of the foraging trips turn into more of scouting trips so the alpha male can mark the outer boundaries of the territory. These tend to be days of more movement and less foraging for food.
Fights happen between rival Meerkat gangs. It generally happens for two reasons. One is territory conflict. When one gang encroaches on another gangs territory. Once the two gangs come in contact with one another they group up together and fluff their fur out and jump up and down to make themselves appear bigger, also making allot of noise. This is called mobbing. Each gang is assessing the others strength. Sometimes they separating and go opposite directions other times a ferocious fight breaks out. Meerkats will kill rival gang members if they can. Also during a fight 2 or 3 Meerkats may jump on a rival biting and scratching him. It will look like a big pile of dust. During or directly after attacks, the dominant male will take a few minutes to asses the situation and decide weather there was a victory or his gang members have fled, in this case he will retreat himself. The other case happens when roaming Meerkats either solo or in small groups are looking for better breeding possibilities try to join other gangs. Mobbing occurs and they may be or may not be successful at joining the gang..
#How did the Meerkat evolve
How did the Meerkat evolve - According to Sean Doolan, they evolved from the southern tip of Africa or the Cape of Good Hope,where a type of extinct Meerkat, called the Suricata Suricatta major, has been found . The extinct Meerkat was similar to the banded mongoose. The current theory is that the Meerkat evolved from the banded mongoose. As the weather climate changed in the region, so did the Meerkats ability to survive in drier conditions.
Why the meerkat stands - Meerkats walk and run on all four, there head is only six inches above ground in this state. When they stand, their total height is 12 inches, providing them with a much better vantage point to see danger. In order to attain an even better vantage point, they will also climb trees and bushes. Their vision is good but depth perception does not appear to be as strong. They bob their head up and down to get distance measurement when objects or close. this gives them different focal points.When facing a threat, they will stand, arch their bodies and erect their tails in an attempt to appear bigger.
What threatens Meerkats? - The threats to a meerkat come from sky, land and weather. In the sky, the Martial Eagle, with a wing span of six feet, can easily prey on adults, while other smaller birds of prey prefer to snatch the young. When the winged predator is seen the alarm goes out and all sprint for nearby bolt holes. If they are not near any bolt holes the will lie on the ground and depend on camouflage They also may take cover in thorny bushes where the birds dare not venture. On the ground, the jackal and other wild cats are the Meerkats primary foe; however, when banded together, Meerkats have the ability to chase away a jackal. Badgers can also be a threat, as their burrowing can penetrate the Meerkats den making them more vulnerable prey. As mentioned previously, the cobra sometimes threatens meerkat young. Meerkats will mob a cobra relentlessly if it tries to enter their burrow. They are agile enough to avoid a snakes strike. They even have the ability to kill a cobra. If they come across one while our foraging they will temporarily mob it and once the situation is under control move on. A puff header snake will also eat Meerkat pups. I have read about a sighting in which a group of Banded mongooses actually climbed a tree to rescue one of their family members from a eagle. Both the Banded mongoose and the meerkat have similar social habits.
Meerkats are also threatened by other competitive gangs as mentioned above. The sentry's alarm will sound if another gang of Meerkats is encroaching upon marked territory. The fights are fierce but sometimes fatal as submission is the goal. The winners, usually the larger of the groups, take or keep the burrow system in question. One interesting note after the fight and Meerkats try and rejoin there gang small fight break out because they have difficulty recognizing each other by sight. The Meerkat rejoining their gang may smell like the rival gang. After the conflict, the winners will hug and congratulate each other with human-like gestures, this is rely remarking each other.. Often non-dominant Meerkats defect from the losing group to the winner's side.
The summer rains also threaten the Meerkats. When rain approaches, the sentry sends the alarm off. As there are often newborns during this time, they must make sure the are on high ground so to avoid a flooding of the burrow system. The alpha female will transport the young one by one to the higher ground burrow. At night they may get stuck in a flooding burrow system.
The most famous of all Meerkats - There are two famous Meerkats that should be mentioned One is Timone, who was featured in the Lion King. Timone, the cartoon character, is based on the real-life Meerkat Timone who which is domesticated resides outside of Palm Springs, California at the only private refuge for Meerkats in existence. For more information, visit www.meerkats.com. You can actually go and visit Timone and hand feed other Meerkats there. I did and it was a terrific experience.
The second is Ziziphus of the Lazuli gang. She is a wild Meerkat and lives in the Kalahari and has been the subject of numerous documentaries and films. One of her more prominent projects is Walking With Meerkats which is a National Geographic documtory filmed in 2000.
Meerkat communication - Meerkats constantly communicate with one another in three different ways: scent, sound, and body language. There have over 20 different sounds that have been recorded which have different meanings. These calls can be broken down into six different groups: lost calls, alarm calls, leading the group calls, pup feeding calls, guarding calls, and foraging calls. For example, while out looking for food, they are are constantly communicating in what sounds like a kind of growling. It helps them to keep track of one another's location since they forage up to 15 feet (5 meters) apart. When the young are learning how to forage, they are very loud and can be heard up to a hundred yards away. If they become separated from the adults, the volume of their cries increases so that an adult will come to get them. They have numerous sounds that are used when grooming and playing
When on guard duty, there is an entirely different assortment of sounds employed. These sounds are constant and communicate to everyone else what is happening during the watch. When everything is fine, the sentry emits mellow tones. When a predator is spotted at a distance, a beeping sound is given, almost like a yellow alert. If the predator gets closer, the sound differentiates depending on the type of predator. The martial eagle tends to get the most frantic alarm even from great distance. Meerkats allow some predators to get very close before they sound the red alert (up to 100 feet from the den).
One last interesting point, sound can be broken up into one, two, three, and even four syllable calls.
How the seasons effect Meerkats -
In the Savanna desert, temperatures can vary greatly. Remember, Meerkats live on southern hemisphere as opposed to the United States and Europe which are on the northern hemisphere. South of the equator and the seasons are opposite of those in the northern hemisphere. The Kalahari summer is considered the wet season, . The summer months October to April temperature can reach 115 (f) or around 40 (c) which can give a sand temperature of 158 (f) or 70(c). In this harsh environment the difference between being in the sun and shade can be up to 86 (f) or 30 (c). The winter months from May to September are very different from the summer, you will see highs around 70 (f) or 22 (c) during the short days and lows at night down below freezing to 14 (f) or -10 (c). Winter is the dry season. Because of these dramatic temperature changes, their feeding habits change accordingly
In the wet season or summer, Meerkats get up early in order to avoid looking for food in the heat. As the day gets warmer, they look for food in shaded areas. At mid-day they return to their den or find a nice, shaded spot for a mid-day nap. If they nap outside, they will lie on their belly with legs stretched out and often throw cooler sand on their back. They will pant during the summer this aids in reducing their body temperature. The yellow mongoose shares this behavior. They wake for a late afternoon feeding which ends at sunset. This season is a virtual feast for Meerkats, as the rain brings out an abundance of food and vegetation especially towards the end of summer from January to April. Grasses on the dunes can reach heights of over three feet tall! Meerkats will eat to their hearts content and their little bellies stick out.
In the dry season or winter, they wait until it warms up a little (9 a.m.) to go and look for food. No mid-day naps at this time. They stay out all day and get back around 4:30 p.m. Meerkats then remain in their den to avoid the rapid and severe temperature change night brings. Food is not as abundant during this time and foraging for food is more difficult. They have to do allot more digging and cover more territory to find adequate nutrition. They will also eat ants, ant eggs, millipedes, and small beetles which are less appealing to them than their summer favorites of lizards, insect larvae, and scorpions.
Meerkats like most other living creatures change their behavior patterns as conditions change. As one reads about the charertistics of any animal you must know whether the animal was observed in captivity or in the wild. Unfortunately most of what has been written about Meerkats has been in captivity, because of the remote habitat where they live makes it hard reach. Therefor it is interesting to understand how their behavior changes when confined to zoos.
The gang will find many differences in captivity. For example food will be abundant and the normal procurement of food such as digging is not necessary. Also space is significantly limited. So the Meerkats will not migrate from burrow to burrow, but stay in one burrow system. They also are not able to forage for food keeping them within meters of there burrow system for their whole lives. Predators are non existent in captivity so there alert systems are dulled. In captivity one will find Meerkats living longer and bigger. Meerkats do fine in captivity, in fact for the Meerkat which spends most of its time looking for food in the wild, this is probably a vacation. In captivity Meerkats are known to mate up to twice a year while in the wild they only mate once a year. Their cuisine is quite different to. In captivity the keepers may feed mice, worms and other sorted insects locally available. A Scorpion, a Meerkat delight would never be seen. Meerkats that don't get along with the gang will be separated and put in another habitat.
Would Meerkats make good pets? - The answer to this question is no, not really. In the United States, you need special permits to keep these animals. The government mandates strict specification for Meerkats enclosures as well as their climate. Meerkats will think your family is their gang and the are the alpha. When you have guest to your home they will get aggressive towards them. A host of other animals would make more appropriate pets! I have run into many people in southern part of Africa that keep Meerkats as pets and say they can be friendly. They are terrific pets though if you have a scorpion infestation problem.

Event Details for: Bullish 200-Day Moving Average Price Cross
Tells Me: The price is generally in an established trend (bullish or bearish) for the time horizon represented by the moving average period (21, 50 or 200 bars). Moving averages are used to smooth out the volatility or "noise" in the price series, to make it easier to discover the underlying trend. By plotting the average price over the last several bars, the line is less "jerky" than plotting the actual prices. A bullish event is generated when the price crosses above the moving average, and in this state, the price is likely in an established uptrend. The opposite is true when the price crosses below the moving average, triggered a bearish event.
Event Date:Mar 03, 2014
Opportunity Type:Long-Term Bullish
Close Price:$0.035

Price crossed above the 200-day moving average.
Your average WashTec at a Total petrol station but an unusual sight because it's located at a (massive) car dealership. They have they own car wash too. The car dealership exists since 50 years or so and had a petrol station from the beggining but a car wash since 1996. Probably a Wesumat because the chassis wash unit seems to be from Wesumat.
Playing catch up!
Here's three mainline Fembots I've been sitting on for a few months - Legacy Minerva, Studio Series BB Movie Arcee, and the Studio Series '86 Animated Arcee.
I'm not entire sure how much exposure she's gotten over the years, but for me, Minerva is the Japanese G1 Headmaster Junior figure that got a gender swap and palette change into Nightbeat, the Private Detective in the Hasbro continuity.
It's nice that she's finally gotten a mainline release, though it would have been nice if she wasn't a repaint/tool of Legacy Elita-1, especially since we just had Headmasters in the Titans Return line.
Other than cosmetic differences, the only other notable difference between the two is that instead of having a pair of Elita-1 ears to plug into the Car mode top, Minerva has a set of Police lights, which have a slot for plugging in her weapon(s).
Unsurprising, the joints on MInerva are worse than on Elita-1.
BB Movie Arcee is an interesting take on the character. Certainly the best live action movie design thus far (though to be fair, the BB Movie designs on the whole aren't bad). Certainly the chunkiest Arcee I've seen, but that's not a terrible thing for a figure of what is supposed to be a war machine.
They're not going to get all of the crazy mechanical details into the figure, but I feel they did a decent job at it, and with the exception of the rear, vehicle mode is actually pretty neat.
Level of articulation is pretty standard for a Deluxe size figure, with above average head rotation capabilities. She also has double elbows thanks to her tranformation.
Of course, it wouldn't be a Hasbro release with some iffy paint work, and of course, some questionable QC, though fortunately the QC issues appear to mainly be the fact that the front tires don't like to clip together, and the head section doesn't like to tab into the chest.
Finally, the Stuido '86 version. Her last Animated style toy, the Siege release, wasn't exactly well received. In fact, it might be one of the laziest Arcee figures ever released by Hasbro. Even the Cyberverse version had more engineering behind it.
Well I'm happy to say that like the Studio Series Hot Rod, there's some pretty good engineering behind this version of Arcee. I can see some ques taken from the MP version, namely the way the chest is handled. Unlike the Siege version, her backpack doesn't detach from the body.
Articulation is once again your typical Deluxe level, The waist joint is fully functional thanks to proper positioning of the backpack parts. Also thanks to the transformation, this Arcee actually has a sort of ab crunch.
QC and paint are.. well, it's Hasbro.

Oxytropis species, California, White Mountains, Sheep Mountain, Fishlake Valley drainage, elevation 3523 m (11560 ft).
This apparently unnamed species is so far known only from this general location, where it grows near and sometimes mixed with two other Oxytropis species, the similar Oxytropis parryi (previous post), and the very different, glandular Oxytropis borealis. Confirmation of the unnamed species awaits comparison with a larger geographic sample of Oxytropis parryi, but for now the following differences are notable:
Oxytropis (unnamed) -- Inflorescence 4-5 flowered, elongating in fruit with lower bracts and developing fruits visibly separating; calyx becoming somewhat enlarged and papery; leaves green, averaging more and smaller leaflets; leaflets mostly 7-9 lateral pairs, hairs loosely ascending; hairs of scapes, petioles, and calyces mostly widely spreading; outer leaves and scapes spreading or decumbent.
Oxytropis parryi (previous post) -- Inflorescence 1-3(-4) flowered, remaining compact in fruit, bracts and fruits not visibly separating; calyx not enlarging; leaves grayish green, averaging fewer and larger leaflets; leaflets mostly 4-6(-7) lateral pairs, hairs appressed; hairs of scapes, petioles, and calyces mostly ascending to appressed; outer leaves and scapes ascending to erect.
In several of the above characters, the plants are intermediate with Oxytropis borealis, so it's also possible that these are hybrids or a hybrid-derivative lineage. But the glands of O. borealis are apparently missing, so I have my doubts about a hybrid hypothesis.
Also visible in this image are King sandwort (Eremogone kingii glabrescens) and alpine sagebrush (Artemisia rothrockii, gray form).
Pushkar (Hindi: पुष्कर) is a town in the Ajmer district in the Indian state of Rajasthan. It is situated 14 km northwest of Ajmer at an average elevation of 510 m and is one of the five sacred dhams (pilgrimage site) for devout Hindus. According to Hindu theology, the pond at the Katas Raj temple Near Choa Saidan Shah in Chakwal District of Pakistan has a theological association with Shiva; it was formed by the tears of Lord Shiva which he is believed to have shed after the death of his wife, Sati. The story goes that when Sati died, Shiva cried so much and for so long, that his tears created two holy ponds – one at Pushkara in Ajmer in India and the other at Ketaksha, which literally means raining eyes, in Sanskrit. It is from this name that the word Katas is derived. It is often called "Tirth Raj" – the king of pilgrimage sites – and has in recent years become a popular destination for foreign tourists.
Pushkar is one of the oldest existing cities of India. It lies on the shore of Pushkar Lake. The date of its actual origin is not known, but legend associates Brahma with its creation.
Pushkar has many temples. Most of the temples are not very old because MANY TEMPLES WERE DESTROYED DURING MUSLIM CONQUESTS in the area. Subsequently, the destroyed temples were rebuilt. The most famous among all is the Brahma Temple built during the 14th century CE. Very few temples to Lord Brahma exist anywhere in the world. Other temples of Brahma include Bithoor in Uttar Pradesh, India; Khedbrahma in Gujarat, India; village Asotra near Balotra city of Barmer district in Rajasthan; Uttamar Kovil (one of the Divya Desams) near Srirangam, Tamil Nadu; Mother Temple of Besakih in Bali, Indonesia; and Prambanan in Yogyakarta, Indonesia. The Pushkar lake has 52 ghats where pilgrims descend to the lake to bathe in the sacred waters.
Pushkar is also famous for its annual fair (Pushkar Camel Fair) held in November.
ETYMOLOGY
Pushkar in Sanskrit means blue lotus flower. Hindus believe that the gods released a swan with a lotus in its beak and let it fall on earth where Brahma would perform a grand yagna. The place where the lotus fell was called Pushkar. Pushkar word may be derived from word 'Pushkarni'means- lake. It may be derived from word Pushpa means flower and Kar means hand.
HISTORY
Pushkar is one of the oldest cities of India. The date of its actual founding is not known, but legend associates Brahma with its creation.
According to legend, Brahma was in search of a place for Mahayagna and he found this place suitable. After a long time, Brahma came to known that a demon, Vajranash, was killing people here so the Lord intoned a mantra on a lotus flower and killed the demon. During this process the parts of flower fell on three places which were later known as Jyaistha, Madhya and Kanistha Pushkar. After this Brahma performed a yagna to protect this place from demons. The consort of Brahma, Saraswati, were needed to offer Ahuti for the yagna but she was not there that time so Gayatri, a Gurjar girl, was married to brahma and performned yagna. This act made first wife of Brahma, Saraswati, angry and she cursed Brahma saying that he would be worshiped in Pushkar only.
The Mahabharata says that while laying down a programme for Maharaja Yudhishthara’s travel, “Maharaja after entering the Jungles of Sind and crossing the small rivers on the way should bathe in Pushkara". And, as per Vaman Purana, Prahlada on his pilgrimage to holy places visited Pushkarayana.
A Gurjara Pratihara ruler of Mandore, Nahadarava, restored this tirtha in the seventh century. He got the place cleared and the lake restored by making an embankment on the side of the river Luni. He rebuilt old palaces and built twelve dharmashalas (resting places) and ghats on three sides of the lake.
According to Rajputana Gazetteer Pushkar was held by Chechi Gurjars until about 700 years ago.Later Some shrines were occupied by Kanphati Jogis.
There are still priests from the Gurjar community in Pushkar temple, known as Bhopas.
The sage Parasara is said to have been born here. His descendants, called Parasara Brahamanas, are found in Pushkar and the surrounding area. The famous temple of Jeenmata has been cared for by Parasara Brahmans for the last 1,000 years.
It is also the venue of the annual Pushkar Camel Fair. In 1901, the town was part of the Rajputana Agency had a population of 3,831.
PUSHKAR FAIR
Pushkar fair continues for five days and these five days are a period of relaxation and merry-making for the villagers. This fair time is the most busy time for them, as this is one of the largest cattle fairs in the country. Animals, including over 50,000 camels, are brought from miles around to be traded and sold. Trading is brisk as several thousand heads of cattle exchange hands. All the camels are cleaned, washed, adorned, some are interestingly shorn to form patterns, and special stalls are set up selling finery and jewellery for the camels. Camels at the Pushkar fair are decorated with great care. They wear jewellery of silver and beads. There are silver bells and bangles around their ankles that jangle when they walk. An interesting ritual is the piercing of a camel's nose. It has more than 400 temples including the only one temple in India dedicated to the Hindu God Lord Brahma, the Creator of the Universe.
According to Indian mythology, after visiting all the Hindu pilgrim towns and temples (Four Dhams), if Pushkar is not visited for worship, then salvation is not achieved. According to the Hindu calendar Pushkar Fair commences in Nawami (ninth day of fortnightly phases of moon) and ends in Purnima (Full Moon) in the month of Kartika (October or November according to the lunar calendar). In Pushkar, one of the biggest Cattle Fair is also held for trading purposes and the best cattle in all categories are awarded. Countless people in their colourful attire gather to take a dip in the Holy Lake and pray to the deities. The whole town comes alive with vibrant folk music and dances, magic shows, horse and camel races and various other traditional entertainment competitions.Pushkar, with more than 12 local fairs and festivals of 10–15 days duration is a year round destination. It is a mellow town by the great lake of Pushkar amidst the perfume of jasmine and rose flowers. About 4,000 to 6,000 visitors from all over the world come to Pushkar everyday.
PUSHKAR LAKE
The prime attraction of Pushkar is the Pushkar Lake which is considered sacred like the Mansarovar Lake in Tibet. Pushkar has become a place of Hindu pilgrimage because of this holy lake. Legend has it that this lake was consecrated to Lord Brahma, the creator of the universe when a lotus dropped from his hand into the vale and a lake emerged in that place.
BRAHMA TEMPLE
The most important temple in Pushkar is the Temple of Lord Brahma, one of the holy trinity of Hinduism. The temple enshrines a life-size idol of Lord Brahma.
SAVITRI TEMPLE
This temple that is located at the top of the Ratnagiri Hill is dedicated to Savitri, the wife of Lord Brahma. The temple houses a statue of Goddess Savitri.
WIKIPEDIA
The Bundi Palace is situated on the hillside adjacent to the Taragarh Fort and is notable for its lavish traditional murals and frescoes. The Chitrashala (picture gallery) of the palace is open to the general public.
____________________________
Bundi is a city with 104,457 101,000 inhabitants (2011) in the Hadoti region of Rajasthan state in northwest India. It is of particular architectural note for its ornate forts, palaces, and stepwell reservoirs known as baoris. It is the administrative headquarters of Bundi District.
GEOGRAPHY
The town of Bundi is situated 35 km from Kota and 210 km from Jaipur. It is located at 25.44°N 75.64°E and an average elevation of 268 metres. The city lies near a narrow gorge, and is surrounded on three sides by hills of the Aravalli Range. A substantial wall with four gateways encircles the city. The town of Indragarh and nearby places are famous for the renowned temples of Bijasan Mata and Kamleshwar. The Indargarh step well is considered as one of the most attractive places in the Bundi district, especially during the rainy season.
DEMOGRAPHICS
In the 2001 Indian census, Bundi had a population of 88,312. Males constitute 53% of the population and females 47%. Bundi has an average literacy rate of 67%, higher than the national average of 59.5%; with male literacy of 75% and female literacy of 57%. 14% of the population is under 6 years of age. In the 2011 Indian census Bundi has a population of 104,457 people.
HISTORY
In ancient times, the area around Bundi was apparently inhabited by various local tribes. Bundi and the eponymous princely state are said to derive their names from a former Meena tribe man called Bunda Meena. Bundi was previously called “Bunda-Ka-Nal", Nal meaning “narrow ways”. Later the region was governed by Rao Deva Hada, who took over Bundi from Jaita Meena in 1342, and established a princely state Bundi, renaming the surrounding area called Hadoti, the land of great Hada Rajputs.
MUGHAL ERA
Rao Surjan (1554–85) given Ranthambore Fort to Akbar in 1533. He was subsequently rewarded by Akbar with additional territory which expanded his kingdom. Both he and his successors entered the service of the Mughals and became one of their closest allies. From this time the rulers of Bundi bore the title of "Rao Raja".
One of the most notable rulers was Rao Ratan Singh Hada (1607–31) who saw service during the reign of the Emperor Jahangir. When Mughal Prince Khurram rebelled against his father, and gained the support of 22 Rajput princes, Rattan Singh stayed loyal to Jahangir. He defeated Prince Khurram at the battle of Burhanpur during which two of his sons were badly wounded. As a reward for his service Jahangir gave Ratan Singh many honours. With his 14 year old son Madho Singh having proven himself during the suppression of the rebellion as a courageous warrior Ratan Singh carved out of Bundi in 1580 sufficient land to create for Madho Singh the independent principality of Kota. Part of Kota was later used to create the separate Jhalawar State in 1838. Despite the loss of land to the new kingdom Ratan Singh retained sufficient territory and revenues to begin construction of the Garh palace.
Rao Chhattra Sal (1632–58) built the temple of Keshavarao at Patan and Chattra Mahal at Bundi. He saw service with the Mughal forces in the Deccan and was trusted by Dara Shikoh with governorship of Delhi, a rare privilege for a Rajput. He remained loyal to Shah Jahan and Dara Shikoh during the rebellion of Aurangzeb despite many temptations and died fighting at the head of his troops at the battle of Samurgarh in 1658 along with his youngest son Bharat Singh. Rao Bhao Singh (1658–78) the eldest son of Chhattar Sal succeeded his father to the throne of Bundi. When after the defeat of Dara Shikoh and his imprisonment of Shah Jahan, Aurangzeb became the Mughul emperor he dispatched troop under the command of Atmaram Gaur and Barh Singh Bundela to conquer Bundi. When they failed Aurangzeb made peace with Bhao Singh. Bhao Singh became sufficiently reconciled to Aurangzeb that he fought for him against Shivaji and at one time served as governor of Aurangabad. When his own son died during his lifetime he adopted Kishan Singh, the son of his brother Bhim Singh. When Kishan Singh too died early his 15 year old son Anirudh Singh (1682 to 1696) succeeded Bhao Singh on the throne.
Anirudh Singh served Aurangzeb in the Deccan and in the northwest under Prince Muazzam where he died. He was succeed by his eldest son Budha Singh, whose service to Muazzam (later Emperor Bahadur Shah I) in the war of succession to the Mughul throne saw the Bundi become dominate over Kota those ruler had backed the losing side.
During the reign of Rao Budh Singh (1696 to 1735) despite him being married to the sister of Jai Singh II of Jaipur, a bitter feud broke out between Bundi and the Kachwaha rulers of Amber (later called Jaipur) which led to him being expelled from his kingdom by surprise attack by the Kachwaha forces in 1702. He regained and lost his kingdom four times before he died in exile while Jaipur and Kota annexed large portion of his territory. It wasn’t until 1739 before the Bundi rulers were able to regain control of their kingdom after enlisting the aid of the Maratha general Malhar Rao Holkar who kept the estate of Patan for his services.
Relations became uneasy with Mewar after Prince Ajit Singh the heir to the Bundi throne killed Rana Ari Singh of Udaipur during the annual Aheria (Bundi’s ritual spring hunt) in 1773. Through claimed to be an accident Mewar historical records consider that it was an assassination which removed an unpopular ruler.
According to an ancient prophecy made by a dying sati it was said that if the rulers of Bundi and Mewar should ever meet at the event one of the two would die. According to legend, over the centuries such a meeting took place four times and on each occasion one of the rulers was killed by the other. Mewar sources indicate that there was only one other occasion when a Mewar ruler died when in 1531 Maharana Ratan Singh II of Mewar, accompanied Prince Surajmal of Bundi on a hunt. The two men despised each other. During the hunt the Maharana attacked Prince Surajmal which ended with both dying within minutes of each other.
BRITISH ERA
In 1804 Rao Raja Bishan Singh (1773–1821) gave valuable assistance to Colonel Monson in his disastrous retreat before Holkar, in revenge for which the Maratha Empire and Pindaris continually ravaged his state and forced the kingdom to pay tribute up to 1817 This led to Bishan Singh signing a subsidiary alliance with the British East India Company on 10 February 1818, which bought him under its protection. Bishan Singh was responsible for the creation of the pleasure palace of Sukh Niwas on the outskirts of Bundi.
Bishan Singh when dying of cholera entrusted James Tod with guardianship of his 11-year old son, Ram Singh. Maharao Raja Ram Singh (1821–89) grew up to be a much respected ruler who initiated economic and administrative reforms as well as establishing schools for the teaching of Sanskrit. On the throne for 68 years he was described as a grand specimen of the Rajput gentleman and "the most conservative prince in conservative Rajputana." His rule was popular and beneficial; and though during the mutiny of 1857 his attitude was equivocal, he continued to enjoy the confidence of the British, being created G.C.S.I. and a counsellor of the empire in 1877 and C.I.E. in 1878. He was succeeded by his adopted son Raghubir Singh (1889–1927), who was made a K.C.S.I. in 1897 and a G.C.I.E. in 1901. His reign was blighted by two disastrous famines which despite his best attempts to alleviated saw the population of his kingdom reduced from some 258,000 to 171,000 by 1901 due to death and immigration. Raghubir Singh supported the British during the World War I.[citation needed]
Maharao Bahadur Singh (1945–77) also supported the British and served in the Burma campaign where he earned the Military Cross for his gallantry before succeeding to the throne. He was a guest at the 1947 wedding of Princess Elizabeth and Philip, Duke of Edinburgh.
ACCESSION TO INDIA
At the time of the partition of India in 1947, the British abandoned their suzerainty over the princely states, which were left to decide whether to remain independent or to accede to the newly independent Dominion of India or to Pakistan. The ruler of the state of Bundi decided to accede to India, which later became the Union of India. This brought the internal affairs of Bundi under the control of Delhi.

COAT OF ARMS
Bundi’s coat of arms is a shield depicting Garuda, the mount of Vishnu, flanked by winged griffins. The shield is flanked by bulls representing dharma or righteousness; it is crowned by a warrior emerging from flames, signifying the creation-legend of the ruling Chauhan clan, which was supposedly created from fire.
TOURIST ATTRACTIONS
- The Taragarh Fort, or 'Star Fort' is the most impressive of the city's structures. It was constructed in AD 1354 upon the top of steep hillside overlooking the city. The largest of its battlements is the 16th century bastion known as the Bhim Burj, on which was once mounted a particularly large cannon called Garbh Gunjam, or 'Thunder from the Womb'. The fort is a popular tourist viewpoint of the city below. The fort contains three tanks which never dry up. The technique with which they were built has been long since lost but the tanks survive as a testament to the advanced methods of construction and engineering in medieval India.
- The Bundi Palace is situated on the hillside adjacent to the Taragarh Fort and is notable for its lavish traditional murals and frescoes. The Chitrashala (picture gallery) of the palace is open to the general public.
- The largest of Bundi's baoris or stepwells is the intricately carved Raniji ki Baori. Some 46 m deep, it was built in 1699 by Rani Nathavatji. The steps built into the sides of the water-well made water accessible even when at a very low level. The baori is one of the largest examples of its kind in Rajasthan.
- The Nawal Sagar is a large square-shaped artificial lake in the centre of Bundi containing many small islets. A temple dedicated to Varuna, the vedic god of water, stands half-submerged in the middle of the lake. the lake feeds the numerous bavdis in the old city by creating an artificial water table.
- The Nagar Sagar twin step wells are identical step wells crafted in pristine masonry on either side of the main spine of Bundi town. The kunds (pools) are currently full of waste from the ancient vegetable market in the vicinity.
- The Dabhai Kund also known as the jail kund, is the largest of the kunds in Bundi. Though slightly overgrown, it is well worth a visit for the spectacular carvings on the numerous steps leading down to the water level.
THE STEPWELLS
There are over 50 stepwells in Bundi, of which only a handful have been maintained. They used to be the only source of water for the town until a piped water system was introduced. After that these stepwells were abandoned and the monuments fell into disrepair. Most of the former stepwells inside the town have become garbage dumps, and are slipping out of the public consciousness.

WIKIPEDIA
The Moscow Kremlin, commonly known simply as the Kremlin, is a fortified complex in Moscow, Russia. Located in the historic centre of the country's capital city, the Kremlin comprises five palaces, four cathedrals, and an enclosing wall along with numerous towers. Within the complex is the Grand Kremlin Palace, which was one of the royal residences of the Tsar of Russia, and is now the residence of the president of the Russian Federation. The Kremlin overlooks the Moskva River to the south, Red Square to the east, and Alexander Garden to the west.
The site had been continuously inhabited by the Meryans since the 2nd century BCE. The Slavs occupied the south-western portion of Borovitsky Hill as early as the 11th century, as evidenced by a metropolitan seal from the 1090s which was unearthed by Soviet archaeologists in the area. The Vyatichi built a fortified structure (or "grad") on the hill where the Neglinnaya River flowed into the Moskva River.
Up to the 14th century, the site was known as the "grad of Moscow". The word "Kremlin" was first recorded in 1331 (though etymologist Max Vasmer mentions an earlier appearance in 1320). The grad was greatly extended by Prince Yuri Dolgorukiy in 1156, it was destroyed by the Mongols in 1237 and rebuilt in oak by Ivan I Kalita in 1339.

Meerkats are born with hair but not full coats and with their eyes closed. They will live in the wild up to 10 years. However, in captivity they can live to be 15 years of age. Although they are relatively healthy animals, they are unfortunately prone to bovine tuberculosis and have been known to get rabies. When they are adults at about one year of age they will weigh around 2 pounds (750 - 820 grams) and stand an average of 12 inches high (30 centimeters). When they are on all four of their feet their height is only 6 inches (15 centimeters). Like all mongooses, they are agile hunters; however, they differ considerably from most of their other relatives. Unlike the typical mongoose of which there are around 35 types, Meerkats live in communities and depend on one another for survival. There are three other types of sociable mongooses, the Banded, the Kousi Mansi and the Dwarf mongooses. They also live in groups, but are not usually found in the Kalahari desert. While most mongooses are nocturnal, Meerkats hunt during the day. They live at night in burrows, which are complex tunnel systems consisting of mounds, access holes, and tunnels which lead to numerous sleeping chambers. A Meerkat community is called a mob or gang, and can number up to 40. There is always a dominate alpha male and dominate alpha female in each gang. The Meerkats larger mongoose relatives typically live alone or in pairs. These intelligent animals are extremely communicative and posses a large vocabulary. They flourish in their environment and are not endangered.
Meerkats live in southern part of Africa which is dominated by the Kalahari desert - The Kalahari spreads over the countries of South Africa, Namibia, Angola, Botswana, and Zimbabwe. The Kalahari desert has little rainfall and an arid climate with open plains. It spreads across the Southern part of Africa covering over one million square miles and is 10 times the size of Great Britain. The land is covered by a porous or soft sand that in many places is bright orange in color. The temperature in the summer months of October to April can reach 115 (f) or around 40 (c) which can give a sand temperature of 158 (f) or 70(c). In this harsh environment the difference between being in the sun and shade can be up to 86 (f) or 30 (c). The winter months from May to September are very different from the summer, you will see highs around 70 (f) or 22 (c) during the short days and lows at night down to 14 (f) or -10 (c). Winter is the dry season.
The average rainfall is 12 inches (300 millimeters) which comes between January and April. This is towards the end of the summer. There is little surface water but there is quite a bit of moisture below the sand. Generally, the broad plains of the Kalahari are covered with a thin coat of different types of grass and thorn scrub. When it rains during the summer, which is rare, the desert transforms into a lush carpet of plants, grasses, and flowers.
The Kalahari consists of both soft and compacted sands, ranging in color from bright orange to white. Meerkats like the soft sand when digging for food as it lessons the energy requirements in this harsh environment. However, they prefer compact sand to build their burrows which would collapse in softer sands. There could be any number of reasons Meerkats flourish in this environment, though all relate to competition for food and predators. One could speculate that the Meerkat may be a weaker type of mongoose that would find competing for food with other mongooses a tremendous hardship or that their coats would stand out making them easy prey for others. What is known is that Meerkats have specially adapted to the Kalahari, which is described later. The Yellow and the Slender mongooses also live in the Kalahari but generally live in harmony with the Meerkats. This is primarily because they each have a different diet and are not in competition for food. Unfortunately the Yellow mongoose will sometimes eat a Meerkat pup (baby), so meerkats will keep their distance from Yellows when there are pups around. Many other animals have also adapted over time in order to survive in this harsh environment, making the Kalahari a remarkable and interesting place. Even within this barren and harsh environment, animals and plant life flourish.
Animals in the Kalahari have a 40% lower metabolic rate then their counterparts in other parts of the world. This adaptation allows animals to survive with less food and water. Of course,the Kalahari's intense heat puts animals at risk of overheating, making the ability to efficiently regulate body temperature a necessity. Body size is key, the smaller the animal the faster the loss and gain of body heat. The "mouse-to-elephant curve" measures this relationship. The general idea is as follows, a gerbil has a 50 times higher metabolic rate than a elephant (per gram of bodyweight); therefore, the amount of energy from food that the gerbil needs to maintain its body temperature is greater than the elephants, making the need for food gathering almost constant. The Meerkat looses 5% of its body weight over night making the search for food very important every day. Can you imagine losing 5% of your body weight over night ? They can also get their fluid requirements from what they eat, so water sources while not a neccessity are helpful.

Meerkat characteristics - Meerkats at adulthood will grow to a standing height of 12 inches (30 centimeters) and weigh around 2 lbs. (750-820 grams). A pregnant female will weigh around 2.8 lb. (1.1 kilos). Their legs are short and their bodies are long and thin. Their tails are also long and thin with a dark tip. The reason for the dark tip is to identify other gang members while foraging for food. Meerkats forage for food with their tails in an upright position enabling them to easily identify their fellow gang members. Meerkats reach sexual maturity at 10 months and adulthood at 11 months. Both males and females share similar physical traits such as short hair and gray or tan markings. The markings on their backs are unique and no two are the same. They have dark brown or black bands around their eyes. Their ears are tipped with black or dark brown. They have dark bands on their sides and back. Their faces and throat are predominately a shade of white. There are four digits on each foot with very sharp non-retractile claws which are curved. They use their claws to dig their burrows. Meerkats also have the unique ability to close their ears, this is to keep dirt out while they burrow, which they do quite often.
Meerkats fur ranges in color from silver to orange to brown. Much of this depends on the subspecies as well as the sand color in which they live.Even in close proximity in the Kalahari you will find Meerkats with tanish fur in the dried out riverbeds and orange fur in the dunes above. Their coats have a great ability to act as both an insulation to keep heat in and an exhaust system to prevent them from overheating in the harsh climate. In the winter they will spread their hair out so to create a heat insulation effect much like a wet suit. Their stomach acts as a sort of solar panel during the winter months. Under a thin layer of stomach hair is a patch of dark skin which collects heat from the winter sun in order to provide warmth on cool days.
Meerkats vision is outstanding. They have a dark band around their eyes, which reduces any glare from the sun. As a result, Meerkats have the ability to see a predatory bird as they look directly into the sun. A Meerkat removes sand from its eyes by blinking. Between the eye and eye lid there is a white membrane called the nictitating membrane. This membrane acts as a windshield wiper and removes sand from their eyes with every blink. However, their ability to see things close up is not as good. Furthermore, they seem to have a problem with depth perception, not being able to focus within 20 feet (6 meters) of themselves. Often they will bob their head up and down trying to get the perspective right. As a result of this nearsightedness, they will often miss food directly in front of them. They often depend on their sense of smell to find food.

Meerkat cuisine .- Agile Meerkats always forage for their food in groups but catch and eat their food alone as their diet usually consist of small portions. As they search for their food they spread apart from one another on the desert floor. This distance between foraging Meerkats averages from 6 feet (2 meters) to 45 feet (15 meters), but can extend to 150 feet (50meters). The distance often depends on the availability of food. Generally Meerkats stay at their burrow one or two nights, so there line of foraging is usually from one burrow system to the next. During the winter when there is no grass and food is sparse they have been seen being as far as 150 feet (50 meters) apart. In the late summer when desert grass may reach three feet high and food is abundant they will forage about 6 feet (2 meters) apart. Meerkats frequently communicate with each other while they are looking for food in order to warn of possible dangers in the area or hear a distress call if one gets lost. Usually there is a Meerkat acting as a sentry watching for danger as the others look for food. This is usually the one that is the best fed at the time, there is no evidence that either sex has a predominance for sentry duty. If trouble arises, an alarm is sounded by the sentry and the gang will band together in a mob ( a mob is when Meerkats band together to fight) to assess what the danger is, and take appropriate defense actions. Meerkats will sometimes collect food for their pups and babysitters back at the den. The young pups as they learn to search for food will follow the adults to help supplement their diet. Current studies show that the pup that gives the loudest begging call gets the most food from the adults.
Most of the Meerkats food is found underground and their specially adapted bodies are perfect for this. Their front claws are curved and act as shovels. They often have to dig their own body weight in dirt just to get a small insect. Foraging for a Meerkat means digging here and there and occasionally finding a tasty morsel on the surface then moving forward with the gang on the endless search for food. A typical Meerkats diet consists of worms, crickets, grasshoppers, small rodents, lizards, small snakes, birds, eggs, fruit, and ant larvae (which they especially love). Insects are a particularly good source of nutrition for the Meerkats because they reproduce rapidly and supply an almost constant food source. I have even had the rare chance to see a Meerkat find a Kalahari truffle which is rare and very expensive in stores. He seemed to enjoy it immensely. Meerkats also love to eat poisonous scorpions which are plentiful. They do this by quickly biting off their stingers and then consuming the rest. Meerkats appear to be resistant to many deadly venom's which greatly increases the variety of their diet. A Meerkat will often drag any poisonous prey such as a scorpion or millipede across the sand before eating it. They do this to remove the chemical defenses of their soon to be meal. They will make use of a water source if one is nearby but Meerkats have developed the ability to get all their liquid requirements from their diet. In the summer, the Meerkats must work harder to get their food because the insects have burrowed deeper in the sand in order to be closer to moisture. The rain brings the insects back to the surface, which means feast to the Meerkat.
The Meerkat home - As mentioned previously, the Meerkats live in underground burrows which consist of entrance holes, tunnels, and sleeping chambers. There may be up to 70 different entrances to the burrow system which may also serve as an exit if the Meerkat is inside the burrow system. They are territorial and maintain an area of about one to three square miles. Their territorial expansion depends on the size of the gang, as well as, the abundance of food and water in the area. Meerkats mark their territory with the use of their anal gland or saliva from their cheek. This marking is done by the alpha male of the gang. They will protect their boundaries ferociously against other gangs. They have from 6 to 15 dens in their territory and will move dens every day or two. The breeding burrow ,which is where the offspring are born, is an exception to the frequent moves. Meerkats will stay at a breeding burrow for about three weeks. It is at this time that the young are able leave the burrow and start to learn to forage for food with the adults. In addition to this, the parasite loads become heavy in the burrow and fill with ticks, fleas and other undesirables after three weeks. Breeding burrows differ from other burrows in that they will have higher mounds of sand around the entrance holes. This is a result of the continual renovation of the tunnels and sleeping chambers necessary for the longer stays. The mounds of dirt around the entrances can reach up to three feet high. When breeding is successful Meerkats often return to the same breeding burrows to have there young. As the Meerkats rotate burrows, the insect population of each abandoned burrow has the opportunity to multiply. Furthermore, the burrow system itself needs to regenerate while the feces left behind becomes food for other animals and the parasite load decreases. When dens are not being used, snakes and ground squirrels often find them to be convenient residences. Mixed everywhere in the Meerkat territory are bolt holes. A bolt hole is a small system of entrances and tunnels between burrows. These bolt holes give Meerkats a place to take cover if danger arises if they are out foraging.
The strategic reasoning behind such an elaborate construction of multiple entrances, is to provide many alternative exits if a dangerous intruder should invade their home. Likewise they have multiple entrances in the burrow if the danger is from the outside. They sleep in groups, cuddled up or on top of each other for warmth as they are particularly sensitive to the cold. In the summer they tend to space out when they sleep. Their sleeping chambers are usually 6 to 8 feet under ground. This keeps the temperature in the sleeping chamber at a more constant level, cooler in the summer and warmer in the winter. There are several sleeping chambers in the den but they will only use one at a time, in the breeding burrows there will be more sleeping chambers. They will move sleeping chamber because of build up of contaminates. What may seem odd to you is, Meerkats will urinate in their dens. This could be for several reasons first it may aid in a marking system to one another. Second Meerkats don't survive well alone so to go outside at night to go to the bathroom is not a prudent thing. In captivity though Meerkats can be trained to go to the bathroom in a litter box. There are certain beetles that share their den that they don't eat. These insects will eat their deification. Above the tunnel system, there is usually a dirt mound resulting from all of their excavation. This higher vantage point serves as a lookout point for the small Meerkats. From this outpost of sorts, they can survey the terrain for predators. This done in the the morning before they leave the burrow for foraging and in the evening before they go to bed.
Other animals, such as squirrels or the yellow mongoose, sometimes share the Meerkats burrow. Because these animals do not compete with the Meerkats for food, they are allowed to share the den. When pup are born they will keep the yellow mongoose away because they will eat a Meerkat pup. Predators, such as cobras, are not welcome houseguests. Meerkats will purposely harass a cobra in the open so to discourage it from entering the den.
Meerkats sometimes move their territories when food becomes to sparse or when another gang of Meerkats forces them from their previous den. Often territories overlap one another and a stronger Meerkat gang will overtake a weaker gangs burrow system. This forces the weaker gang to take the loss and try to expand in another direction, or wait tell they are stronger and retake the lost burrow system.

Mating and reproduction - Meerkats try, but do not usually mate for life. Mating in the gang is suppose to be reserved for the alpha male and alpha female, but things happen to change this. First the alpha male might die or be overthrown by another male from inside their gang or another gang. Or the alpha female might mate with a male from a wondering male from another gang while out foraging for food, the alpha male never knowing. What they won't do is mate with another direct family member. When the dominate female is ready to breed she will chase away all the other beta families that can bear children, this will be females at 10 months and older. The temporary outcast will follow the gang until the alpha female has had her pups (babies) and regains her strength. This is done because she wants only her offspring in the gang and another beta female might try and displace her during her weakened time of giving birth. The trailing females often get impregnated from males from other gangs they encounter. Often they will abort these births. If the do give birth they will attempt to sneak them in with the pups of the alpha female. The alpha female will if she notices kill and eat the beta females babies. The beta female have about a 20% chance of getting the young snack in with the alphas females pups. A interesting note, if the alpha female pup die, no other meerkat will eat them. A few days after the birth of the alphas pups, the once outlasted females will rejoin the gang and help with the giving milk to the new pups if they are able. It was once observed that a beta female killed the alpha females pups just after birth and replace them with her pups a few days later, the alpha female not knowing the difference. They can breed every two months but tend to successfully breed two to three times a year depending on food availability. There was one gang observed breeding four times in a year. The gestational period is 70 days resulting in a litter of usually five to six. The pregnant female will increase her body weigh approximately 40% gestation (see - Meerkats are a type of mongoose). The babies, called pups, are born with sparse fur and eyes closed. For the first two weeks they stay in the sleeping chamber and drink their mothers or milk producing females. The third week they will venture outside and stay around the burrow system with a babysitter. . During this period when the alpha female is not feeding the young, babysitters will watch the pups while the alpha female goes out to feed, fortifying her supply of milk and her strength. She will do less sentry duty at this time and never babysitting. From week 4 to week 6 the pups will forage with their elders getting nourishment from both milk and insects. At 6 weeks to 16 weeks they will find their own food as well as be supplemented by the elders, and no longer getting milk. Studies show that the pups that make the loudest begging calls get fed the most from the elders. After sixteen weeks they are on there own to find there food Each pup will be taken on by a adult Meerkat which will act as a mentor, who will take the responsibility to teach the pup necessary skills for foraging for food as well as responding to danger. Male Meerkats tend to mentor male pups and female Meerkats tend to mentor the female pups. Many of skills Meerkats have are taught by the mentors rather then being instinctual.
Meerkats reach sexual maturity at 10 months, and reach adulthood at 11 months. After 10 months a Meerkat may venture out of the gang looking for breeding opportunities. They may also leave to form new gangs or join other gangs. They also may stay with their original gang for up to three years before venturing out. They also may leave in groups of two or three. It takes a brave Meerkat to leave the gang because the road out if filled with many dangers for the sole are small group.
Typical day of a Meerkat - Meerkats are extremely social animals. Observing Meerkats is a wonderful experience. They love grooming one another, wrestling and playing with one other. They have avid curiosities and can make a toy of almost anything. Even with all this play, Meerkats do not ignore the need for security. One Meerkat always seems to be a sentry and stands guard to keep the gang safe.
There typical day consist of, they wake up early in the morning as the first rays of sun stretch across the Kalahari. The first to come out of the burrow is usually the last one in from the preceding night. This Meerkat surveys the area to make sure the coast is clear after that the others start to rise one by one from several entrances. They start by soaking up the sun to warm up there bodies from the nights sleep by facing the sun and using their stomachs as solar panels.. One may observe some digging around the entrances, this seems to be more like exercise to warm their bodies up. Then the young start to scurry around play and grooming one another, as the elders spend time grooming sunning. Once hunger starts to set in, the search for food is on. The alpha male sets the direction for the day and decide weather or not to move towards another burrow system.. Scurrying hear and there and digging here and there, but always one is on sentry. As the day goes on and the heat sets in they will stop for a rest. These rest periods are longer during the summers but so are the days. As the day cools they are off again in the afternoon in search of food. Just before sunset they will arrive at the den for the night. At this time they will commence on repairs of the den as well as well deserved grooming and giving one another affection which is really marking one another with the anal gland or cheek saliva. As the sun falls, they descend one by one into the burrow for sleep all huddled together. Lastly, they don't like the rain and will stay in their burrow and not forage for food until the rain stops.
Interestingly enough Meerkats seem to identify one another my smell rather than sight. That is why the are constantly marking one another. For instance if a Meerkat gets separated for some time and try to rejoin the gang, the gang will think it is a intruder and get in a mobbing defense stance ( mobbing is when they huddle together so to look bigger and present aggressive behavior) until they smell what they think is the unknown Meerkat. Once the sent is recognized everything is fine.

Meerkats social structure - To survive, Meerkats must live in groups for protection, as the desert presents many challenges. Each Meerkat has an important, role to perform. It was first thought Meerkats had well defined roles in their gang from being a sentry to baby sitting to foraging for food for the young. Recent studies have disprove this and actually show that hormonal changes in Meerkats influence their behavior. Also the conditions around the burrow system effect their responsibilities. When food and water is abundant more time is spent being sentries, renovating the burrow systems, relaxing and caring for the young. Some things are instinctual while others are taught to the pups by the elders. For example raising young is a learned behavior for Meerkats. If a pup is separated at birth and kept as a pet, and the pup gets pregnant. She will not know how to raise her young or teach them how to forage for food. Meerkat roles vary:
alpha male - Dominate male of the gang, has breeding rights to the alpha female. The dominate male is not necessarily decided by the largest male in the gang.
alpha female - Dominate female of the gang, all betas are subservient to her. Only one that is suppose to breed in the gang.
beta male - Subservient males will leave the gang by 3 years in search of better breeding opportunities. They are 10 months or older
beta female - Subservient females will support the alpha Meerkats. They will be driven temporally from the gang by the alpha female when she is ready to get pregnant. They will leave the gang by 3 years in search of better breeding opportunities. At 10 months or older they are at sexual maturity.
pups - Meerkat babies, 10 months or younger.
babysitter - Stays with the pups while the gang is out foraging for food. Different gang members take the responsibility different days, this is not domiated by males of females. Generally though the least hungry Meerkat will do the babysitting. The alpha female never baby-sits. This duty is for Meerkats 6 months or older.
sentry - Watches over the gang to spot danger. It is either done standing on the ground or climbing a tree or bush. Known to climb up to 30 feet in a tree to do sentry duty. This duty is not dominated by males or female. There is a sentry on watch both at the burrow system as well as when the gang is foraging for food. During times of less available food less sentry duty is done when searching for food.
excavating - Necessary to renovate burrow systems. Often Meerkats will get one behind another and work together to move sand out of the burrow system. Like how firemen would hand buckets of water to one another to put out a fire in the old days.
mentoring - A elder Meerkat will take on the responsibility of teach a pup the do's and do don'ts of being a Meerkat. This includes how to raise young, how to forage for food, and what dangers lurk about.
grooming - Meerkats like to groom one another, and in fact have a natural reflex to groom when the area where there back and tail meet is stimulated. They will remove ticks and fleas from one anther and actually eat them, though these parasites are not a normal part of the diet
play fighting - Often done by the young in the morning and to a lesser degree in the evening. Adults will also play fight. This teaches the young to fight as well puts a dominance order to the gang.
Beta males and famales often leave the gang by three years to live with different gangs or join together to form different gangs in order to increase their chances to breed. Meerkats that embark on this journey alone or in groups of two or three face great danger, as Meerkats are most vulnerable when they few in number. Sometimes Meerkats will ally themselves with one another and takeover another gang, and getting rid of the competitive alpha male and perhaps the alpha female.
The size and makeup of the meerkat community determines what duties each will have. There is usually a dominate male and female in the community although there also seems to be a second in command. I have seen a case where the alpha female was killed and the alpha male did not seem to know what to do. He had not taken on another alpha female because that would mean a female from the outside. It was felt he would at some point leave the gang in search of throwing out another alpha male from a rival gang. The alpha male is responsible for marking the territory, some of the foraging trips turn into more of scouting trips so the alpha male can mark the outer boundaries of the territory. These tend to be days of more movement and less foraging for food.
Fights happen between rival Meerkat gangs. It generally happens for two reasons. One is territory conflict. When one gang encroaches on another gangs territory. Once the two gangs come in contact with one another they group up together and fluff their fur out and jump up and down to make themselves appear bigger, also making allot of noise. This is called mobbing. Each gang is assessing the others strength. Sometimes they separating and go opposite directions other times a ferocious fight breaks out. Meerkats will kill rival gang members if they can. Also during a fight 2 or 3 Meerkats may jump on a rival biting and scratching him. It will look like a big pile of dust. During or directly after attacks, the dominant male will take a few minutes to asses the situation and decide weather there was a victory or his gang members have fled, in this case he will retreat himself. The other case happens when roaming Meerkats either solo or in small groups are looking for better breeding possibilities try to join other gangs. Mobbing occurs and they may be or may not be successful at joining the gang..
#How did the Meerkat evolve
How did the Meerkat evolve - According to Sean Doolan, they evolved from the southern tip of Africa or the Cape of Good Hope,where a type of extinct Meerkat, called the Suricata Suricatta major, has been found . The extinct Meerkat was similar to the banded mongoose. The current theory is that the Meerkat evolved from the banded mongoose. As the weather climate changed in the region, so did the Meerkats ability to survive in drier conditions.
Why the meerkat stands - Meerkats walk and run on all four, there head is only six inches above ground in this state. When they stand, their total height is 12 inches, providing them with a much better vantage point to see danger. In order to attain an even better vantage point, they will also climb trees and bushes. Their vision is good but depth perception does not appear to be as strong. They bob their head up and down to get distance measurement when objects or close. this gives them different focal points.When facing a threat, they will stand, arch their bodies and erect their tails in an attempt to appear bigger.
What threatens Meerkats? - The threats to a meerkat come from sky, land and weather. In the sky, the Martial Eagle, with a wing span of six feet, can easily prey on adults, while other smaller birds of prey prefer to snatch the young. When the winged predator is seen the alarm goes out and all sprint for nearby bolt holes. If they are not near any bolt holes the will lie on the ground and depend on camouflage They also may take cover in thorny bushes where the birds dare not venture. On the ground, the jackal and other wild cats are the Meerkats primary foe; however, when banded together, Meerkats have the ability to chase away a jackal. Badgers can also be a threat, as their burrowing can penetrate the Meerkats den making them more vulnerable prey. As mentioned previously, the cobra sometimes threatens meerkat young. Meerkats will mob a cobra relentlessly if it tries to enter their burrow. They are agile enough to avoid a snakes strike. They even have the ability to kill a cobra. If they come across one while our foraging they will temporarily mob it and once the situation is under control move on. A puff header snake will also eat Meerkat pups. I have read about a sighting in which a group of Banded mongooses actually climbed a tree to rescue one of their family members from a eagle. Both the Banded mongoose and the meerkat have similar social habits.
Meerkats are also threatened by other competitive gangs as mentioned above. The sentry's alarm will sound if another gang of Meerkats is encroaching upon marked territory. The fights are fierce but sometimes fatal as submission is the goal. The winners, usually the larger of the groups, take or keep the burrow system in question. One interesting note after the fight and Meerkats try and rejoin there gang small fight break out because they have difficulty recognizing each other by sight. The Meerkat rejoining their gang may smell like the rival gang. After the conflict, the winners will hug and congratulate each other with human-like gestures, this is rely remarking each other.. Often non-dominant Meerkats defect from the losing group to the winner's side.
The summer rains also threaten the Meerkats. When rain approaches, the sentry sends the alarm off. As there are often newborns during this time, they must make sure the are on high ground so to avoid a flooding of the burrow system. The alpha female will transport the young one by one to the higher ground burrow. At night they may get stuck in a flooding burrow system.
The most famous of all Meerkats - There are two famous Meerkats that should be mentioned One is Timone, who was featured in the Lion King. Timone, the cartoon character, is based on the real-life Meerkat Timone who which is domesticated resides outside of Palm Springs, California at the only private refuge for Meerkats in existence. For more information, visit www.meerkats.com. You can actually go and visit Timone and hand feed other Meerkats there. I did and it was a terrific experience.
The second is Ziziphus of the Lazuli gang. She is a wild Meerkat and lives in the Kalahari and has been the subject of numerous documentaries and films. One of her more prominent projects is Walking With Meerkats which is a National Geographic documtory filmed in 2000.
Meerkat communication - Meerkats constantly communicate with one another in three different ways: scent, sound, and body language. There have over 20 different sounds that have been recorded which have different meanings. These calls can be broken down into six different groups: lost calls, alarm calls, leading the group calls, pup feeding calls, guarding calls, and foraging calls. For example, while out looking for food, they are are constantly communicating in what sounds like a kind of growling. It helps them to keep track of one another's location since they forage up to 15 feet (5 meters) apart. When the young are learning how to forage, they are very loud and can be heard up to a hundred yards away. If they become separated from the adults, the volume of their cries increases so that an adult will come to get them. They have numerous sounds that are used when grooming and playing
When on guard duty, there is an entirely different assortment of sounds employed. These sounds are constant and communicate to everyone else what is happening during the watch. When everything is fine, the sentry emits mellow tones. When a predator is spotted at a distance, a beeping sound is given, almost like a yellow alert. If the predator gets closer, the sound differentiates depending on the type of predator. The martial eagle tends to get the most frantic alarm even from great distance. Meerkats allow some predators to get very close before they sound the red alert (up to 100 feet from the den).
One last interesting point, sound can be broken up into one, two, three, and even four syllable calls.
How the seasons effect Meerkats -
In the Savanna desert, temperatures can vary greatly. Remember, Meerkats live on southern hemisphere as opposed to the United States and Europe which are on the northern hemisphere. South of the equator and the seasons are opposite of those in the northern hemisphere. The Kalahari summer is considered the wet season, . The summer months October to April temperature can reach 115 (f) or around 40 (c) which can give a sand temperature of 158 (f) or 70(c). In this harsh environment the difference between being in the sun and shade can be up to 86 (f) or 30 (c). The winter months from May to September are very different from the summer, you will see highs around 70 (f) or 22 (c) during the short days and lows at night down below freezing to 14 (f) or -10 (c). Winter is the dry season. Because of these dramatic temperature changes, their feeding habits change accordingly
In the wet season or summer, Meerkats get up early in order to avoid looking for food in the heat. As the day gets warmer, they look for food in shaded areas. At mid-day they return to their den or find a nice, shaded spot for a mid-day nap. If they nap outside, they will lie on their belly with legs stretched out and often throw cooler sand on their back. They will pant during the summer this aids in reducing their body temperature. The yellow mongoose shares this behavior. They wake for a late afternoon feeding which ends at sunset. This season is a virtual feast for Meerkats, as the rain brings out an abundance of food and vegetation especially towards the end of summer from January to April. Grasses on the dunes can reach heights of over three feet tall! Meerkats will eat to their hearts content and their little bellies stick out.
In the dry season or winter, they wait until it warms up a little (9 a.m.) to go and look for food. No mid-day naps at this time. They stay out all day and get back around 4:30 p.m. Meerkats then remain in their den to avoid the rapid and severe temperature change night brings. Food is not as abundant during this time and foraging for food is more difficult. They have to do allot more digging and cover more territory to find adequate nutrition. They will also eat ants, ant eggs, millipedes, and small beetles which are less appealing to them than their summer favorites of lizards, insect larvae, and scorpions.
Meerkats like most other living creatures change their behavior patterns as conditions change. As one reads about the charertistics of any animal you must know whether the animal was observed in captivity or in the wild. Unfortunately most of what has been written about Meerkats has been in captivity, because of the remote habitat where they live makes it hard reach. Therefor it is interesting to understand how their behavior changes when confined to zoos.
The gang will find many differences in captivity. For example food will be abundant and the normal procurement of food such as digging is not necessary. Also space is significantly limited. So the Meerkats will not migrate from burrow to burrow, but stay in one burrow system. They also are not able to forage for food keeping them within meters of there burrow system for their whole lives. Predators are non existent in captivity so there alert systems are dulled. In captivity one will find Meerkats living longer and bigger. Meerkats do fine in captivity, in fact for the Meerkat which spends most of its time looking for food in the wild, this is probably a vacation. In captivity Meerkats are known to mate up to twice a year while in the wild they only mate once a year. Their cuisine is quite different to. In captivity the keepers may feed mice, worms and other sorted insects locally available. A Scorpion, a Meerkat delight would never be seen. Meerkats that don't get along with the gang will be separated and put in another habitat.
Would Meerkats make good pets? - The answer to this question is no, not really. In the United States, you need special permits to keep these animals. The government mandates strict specification for Meerkats enclosures as well as their climate. Meerkats will think your family is their gang and the are the alpha. When you have guest to your home they will get aggressive towards them. A host of other animals would make more appropriate pets! I have run into many people in southern part of Africa that keep Meerkats as pets and say they can be friendly. They are terrific pets though if you have a scorpion infestation problem.
Meerkats are born with hair but not full coats and with their eyes closed. They will live in the wild up to 10 years. However, in captivity they can live to be 15 years of age. Although they are relatively healthy animals, they are unfortunately prone to bovine tuberculosis and have been known to get rabies. When they are adults at about one year of age they will weigh around 2 pounds (750 - 820 grams) and stand an average of 12 inches high (30 centimeters). When they are on all four of their feet their height is only 6 inches (15 centimeters). Like all mongooses, they are agile hunters; however, they differ considerably from most of their other relatives. Unlike the typical mongoose of which there are around 35 types, Meerkats live in communities and depend on one another for survival. There are three other types of sociable mongooses, the Banded, the Kousi Mansi and the Dwarf mongooses. They also live in groups, but are not usually found in the Kalahari desert. While most mongooses are nocturnal, Meerkats hunt during the day. They live at night in burrows, which are complex tunnel systems consisting of mounds, access holes, and tunnels which lead to numerous sleeping chambers. A Meerkat community is called a mob or gang, and can number up to 40. There is always a dominate alpha male and dominate alpha female in each gang. The Meerkats larger mongoose relatives typically live alone or in pairs. These intelligent animals are extremely communicative and posses a large vocabulary. They flourish in their environment and are not endangered.
Meerkats live in southern part of Africa which is dominated by the Kalahari desert - The Kalahari spreads over the countries of South Africa, Namibia, Angola, Botswana, and Zimbabwe. The Kalahari desert has little rainfall and an arid climate with open plains. It spreads across the Southern part of Africa covering over one million square miles and is 10 times the size of Great Britain. The land is covered by a porous or soft sand that in many places is bright orange in color. The temperature in the summer months of October to April can reach 115 (f) or around 40 (c) which can give a sand temperature of 158 (f) or 70(c). In this harsh environment the difference between being in the sun and shade can be up to 86 (f) or 30 (c). The winter months from May to September are very different from the summer, you will see highs around 70 (f) or 22 (c) during the short days and lows at night down to 14 (f) or -10 (c). Winter is the dry season.
The average rainfall is 12 inches (300 millimeters) which comes between January and April. This is towards the end of the summer. There is little surface water but there is quite a bit of moisture below the sand. Generally, the broad plains of the Kalahari are covered with a thin coat of different types of grass and thorn scrub. When it rains during the summer, which is rare, the desert transforms into a lush carpet of plants, grasses, and flowers.
The Kalahari consists of both soft and compacted sands, ranging in color from bright orange to white. Meerkats like the soft sand when digging for food as it lessons the energy requirements in this harsh environment. However, they prefer compact sand to build their burrows which would collapse in softer sands. There could be any number of reasons Meerkats flourish in this environment, though all relate to competition for food and predators. One could speculate that the Meerkat may be a weaker type of mongoose that would find competing for food with other mongooses a tremendous hardship or that their coats would stand out making them easy prey for others. What is known is that Meerkats have specially adapted to the Kalahari, which is described later. The Yellow and the Slender mongooses also live in the Kalahari but generally live in harmony with the Meerkats. This is primarily because they each have a different diet and are not in competition for food. Unfortunately the Yellow mongoose will sometimes eat a Meerkat pup (baby), so meerkats will keep their distance from Yellows when there are pups around. Many other animals have also adapted over time in order to survive in this harsh environment, making the Kalahari a remarkable and interesting place. Even within this barren and harsh environment, animals and plant life flourish.
Animals in the Kalahari have a 40% lower metabolic rate then their counterparts in other parts of the world. This adaptation allows animals to survive with less food and water. Of course,the Kalahari's intense heat puts animals at risk of overheating, making the ability to efficiently regulate body temperature a necessity. Body size is key, the smaller the animal the faster the loss and gain of body heat. The "mouse-to-elephant curve" measures this relationship. The general idea is as follows, a gerbil has a 50 times higher metabolic rate than a elephant (per gram of bodyweight); therefore, the amount of energy from food that the gerbil needs to maintain its body temperature is greater than the elephants, making the need for food gathering almost constant. The Meerkat looses 5% of its body weight over night making the search for food very important every day. Can you imagine losing 5% of your body weight over night ? They can also get their fluid requirements from what they eat, so water sources while not a neccessity are helpful.

Meerkat characteristics - Meerkats at adulthood will grow to a standing height of 12 inches (30 centimeters) and weigh around 2 lbs. (750-820 grams). A pregnant female will weigh around 2.8 lb. (1.1 kilos). Their legs are short and their bodies are long and thin. Their tails are also long and thin with a dark tip. The reason for the dark tip is to identify other gang members while foraging for food. Meerkats forage for food with their tails in an upright position enabling them to easily identify their fellow gang members. Meerkats reach sexual maturity at 10 months and adulthood at 11 months. Both males and females share similar physical traits such as short hair and gray or tan markings. The markings on their backs are unique and no two are the same. They have dark brown or black bands around their eyes. Their ears are tipped with black or dark brown. They have dark bands on their sides and back. Their faces and throat are predominately a shade of white. There are four digits on each foot with very sharp non-retractile claws which are curved. They use their claws to dig their burrows. Meerkats also have the unique ability to close their ears, this is to keep dirt out while they burrow, which they do quite often.
Meerkats fur ranges in color from silver to orange to brown. Much of this depends on the subspecies as well as the sand color in which they live.Even in close proximity in the Kalahari you will find Meerkats with tanish fur in the dried out riverbeds and orange fur in the dunes above. Their coats have a great ability to act as both an insulation to keep heat in and an exhaust system to prevent them from overheating in the harsh climate. In the winter they will spread their hair out so to create a heat insulation effect much like a wet suit. Their stomach acts as a sort of solar panel during the winter months. Under a thin layer of stomach hair is a patch of dark skin which collects heat from the winter sun in order to provide warmth on cool days.
Meerkats vision is outstanding. They have a dark band around their eyes, which reduces any glare from the sun. As a result, Meerkats have the ability to see a predatory bird as they look directly into the sun. A Meerkat removes sand from its eyes by blinking. Between the eye and eye lid there is a white membrane called the nictitating membrane. This membrane acts as a windshield wiper and removes sand from their eyes with every blink. However, their ability to see things close up is not as good. Furthermore, they seem to have a problem with depth perception, not being able to focus within 20 feet (6 meters) of themselves. Often they will bob their head up and down trying to get the perspective right. As a result of this nearsightedness, they will often miss food directly in front of them. They often depend on their sense of smell to find food.

Meerkat cuisine .- Agile Meerkats always forage for their food in groups but catch and eat their food alone as their diet usually consist of small portions. As they search for their food they spread apart from one another on the desert floor. This distance between foraging Meerkats averages from 6 feet (2 meters) to 45 feet (15 meters), but can extend to 150 feet (50meters). The distance often depends on the availability of food. Generally Meerkats stay at their burrow one or two nights, so there line of foraging is usually from one burrow system to the next. During the winter when there is no grass and food is sparse they have been seen being as far as 150 feet (50 meters) apart. In the late summer when desert grass may reach three feet high and food is abundant they will forage about 6 feet (2 meters) apart. Meerkats frequently communicate with each other while they are looking for food in order to warn of possible dangers in the area or hear a distress call if one gets lost. Usually there is a Meerkat acting as a sentry watching for danger as the others look for food. This is usually the one that is the best fed at the time, there is no evidence that either sex has a predominance for sentry duty. If trouble arises, an alarm is sounded by the sentry and the gang will band together in a mob ( a mob is when Meerkats band together to fight) to assess what the danger is, and take appropriate defense actions. Meerkats will sometimes collect food for their pups and babysitters back at the den. The young pups as they learn to search for food will follow the adults to help supplement their diet. Current studies show that the pup that gives the loudest begging call gets the most food from the adults.
Most of the Meerkats food is found underground and their specially adapted bodies are perfect for this. Their front claws are curved and act as shovels. They often have to dig their own body weight in dirt just to get a small insect. Foraging for a Meerkat means digging here and there and occasionally finding a tasty morsel on the surface then moving forward with the gang on the endless search for food. A typical Meerkats diet consists of worms, crickets, grasshoppers, small rodents, lizards, small snakes, birds, eggs, fruit, and ant larvae (which they especially love). Insects are a particularly good source of nutrition for the Meerkats because they reproduce rapidly and supply an almost constant food source. I have even had the rare chance to see a Meerkat find a Kalahari truffle which is rare and very expensive in stores. He seemed to enjoy it immensely. Meerkats also love to eat poisonous scorpions which are plentiful. They do this by quickly biting off their stingers and then consuming the rest. Meerkats appear to be resistant to many deadly venom's which greatly increases the variety of their diet. A Meerkat will often drag any poisonous prey such as a scorpion or millipede across the sand before eating it. They do this to remove the chemical defenses of their soon to be meal. They will make use of a water source if one is nearby but Meerkats have developed the ability to get all their liquid requirements from their diet. In the summer, the Meerkats must work harder to get their food because the insects have burrowed deeper in the sand in order to be closer to moisture. The rain brings the insects back to the surface, which means feast to the Meerkat.
The Meerkat home - As mentioned previously, the Meerkats live in underground burrows which consist of entrance holes, tunnels, and sleeping chambers. There may be up to 70 different entrances to the burrow system which may also serve as an exit if the Meerkat is inside the burrow system. They are territorial and maintain an area of about one to three square miles. Their territorial expansion depends on the size of the gang, as well as, the abundance of food and water in the area. Meerkats mark their territory with the use of their anal gland or saliva from their cheek. This marking is done by the alpha male of the gang. They will protect their boundaries ferociously against other gangs. They have from 6 to 15 dens in their territory and will move dens every day or two. The breeding burrow ,which is where the offspring are born, is an exception to the frequent moves. Meerkats will stay at a breeding burrow for about three weeks. It is at this time that the young are able leave the burrow and start to learn to forage for food with the adults. In addition to this, the parasite loads become heavy in the burrow and fill with ticks, fleas and other undesirables after three weeks. Breeding burrows differ from other burrows in that they will have higher mounds of sand around the entrance holes. This is a result of the continual renovation of the tunnels and sleeping chambers necessary for the longer stays. The mounds of dirt around the entrances can reach up to three feet high. When breeding is successful Meerkats often return to the same breeding burrows to have there young. As the Meerkats rotate burrows, the insect population of each abandoned burrow has the opportunity to multiply. Furthermore, the burrow system itself needs to regenerate while the feces left behind becomes food for other animals and the parasite load decreases. When dens are not being used, snakes and ground squirrels often find them to be convenient residences. Mixed everywhere in the Meerkat territory are bolt holes. A bolt hole is a small system of entrances and tunnels between burrows. These bolt holes give Meerkats a place to take cover if danger arises if they are out foraging.
The strategic reasoning behind such an elaborate construction of multiple entrances, is to provide many alternative exits if a dangerous intruder should invade their home. Likewise they have multiple entrances in the burrow if the danger is from the outside. They sleep in groups, cuddled up or on top of each other for warmth as they are particularly sensitive to the cold. In the summer they tend to space out when they sleep. Their sleeping chambers are usually 6 to 8 feet under ground. This keeps the temperature in the sleeping chamber at a more constant level, cooler in the summer and warmer in the winter. There are several sleeping chambers in the den but they will only use one at a time, in the breeding burrows there will be more sleeping chambers. They will move sleeping chamber because of build up of contaminates. What may seem odd to you is, Meerkats will urinate in their dens. This could be for several reasons first it may aid in a marking system to one another. Second Meerkats don't survive well alone so to go outside at night to go to the bathroom is not a prudent thing. In captivity though Meerkats can be trained to go to the bathroom in a litter box. There are certain beetles that share their den that they don't eat. These insects will eat their deification. Above the tunnel system, there is usually a dirt mound resulting from all of their excavation. This higher vantage point serves as a lookout point for the small Meerkats. From this outpost of sorts, they can survey the terrain for predators. This done in the the morning before they leave the burrow for foraging and in the evening before they go to bed.
Other animals, such as squirrels or the yellow mongoose, sometimes share the Meerkats burrow. Because these animals do not compete with the Meerkats for food, they are allowed to share the den. When pup are born they will keep the yellow mongoose away because they will eat a Meerkat pup. Predators, such as cobras, are not welcome houseguests. Meerkats will purposely harass a cobra in the open so to discourage it from entering the den.
Meerkats sometimes move their territories when food becomes to sparse or when another gang of Meerkats forces them from their previous den. Often territories overlap one another and a stronger Meerkat gang will overtake a weaker gangs burrow system. This forces the weaker gang to take the loss and try to expand in another direction, or wait tell they are stronger and retake the lost burrow system.

Mating and reproduction - Meerkats try, but do not usually mate for life. Mating in the gang is suppose to be reserved for the alpha male and alpha female, but things happen to change this. First the alpha male might die or be overthrown by another male from inside their gang or another gang. Or the alpha female might mate with a male from a wondering male from another gang while out foraging for food, the alpha male never knowing. What they won't do is mate with another direct family member. When the dominate female is ready to breed she will chase away all the other beta families that can bear children, this will be females at 10 months and older. The temporary outcast will follow the gang until the alpha female has had her pups (babies) and regains her strength. This is done because she wants only her offspring in the gang and another beta female might try and displace her during her weakened time of giving birth. The trailing females often get impregnated from males from other gangs they encounter. Often they will abort these births. If the do give birth they will attempt to sneak them in with the pups of the alpha female. The alpha female will if she notices kill and eat the beta females babies. The beta female have about a 20% chance of getting the young snack in with the alphas females pups. A interesting note, if the alpha female pup die, no other meerkat will eat them. A few days after the birth of the alphas pups, the once outlasted females will rejoin the gang and help with the giving milk to the new pups if they are able. It was once observed that a beta female killed the alpha females pups just after birth and replace them with her pups a few days later, the alpha female not knowing the difference. They can breed every two months but tend to successfully breed two to three times a year depending on food availability. There was one gang observed breeding four times in a year. The gestational period is 70 days resulting in a litter of usually five to six. The pregnant female will increase her body weigh approximately 40% gestation (see - Meerkats are a type of mongoose). The babies, called pups, are born with sparse fur and eyes closed. For the first two weeks they stay in the sleeping chamber and drink their mothers or milk producing females. The third week they will venture outside and stay around the burrow system with a babysitter. . During this period when the alpha female is not feeding the young, babysitters will watch the pups while the alpha female goes out to feed, fortifying her supply of milk and her strength. She will do less sentry duty at this time and never babysitting. From week 4 to week 6 the pups will forage with their elders getting nourishment from both milk and insects. At 6 weeks to 16 weeks they will find their own food as well as be supplemented by the elders, and no longer getting milk. Studies show that the pups that make the loudest begging calls get fed the most from the elders. After sixteen weeks they are on there own to find there food Each pup will be taken on by a adult Meerkat which will act as a mentor, who will take the responsibility to teach the pup necessary skills for foraging for food as well as responding to danger. Male Meerkats tend to mentor male pups and female Meerkats tend to mentor the female pups. Many of skills Meerkats have are taught by the mentors rather then being instinctual.
Meerkats reach sexual maturity at 10 months, and reach adulthood at 11 months. After 10 months a Meerkat may venture out of the gang looking for breeding opportunities. They may also leave to form new gangs or join other gangs. They also may stay with their original gang for up to three years before venturing out. They also may leave in groups of two or three. It takes a brave Meerkat to leave the gang because the road out if filled with many dangers for the sole are small group.
Typical day of a Meerkat - Meerkats are extremely social animals. Observing Meerkats is a wonderful experience. They love grooming one another, wrestling and playing with one other. They have avid curiosities and can make a toy of almost anything. Even with all this play, Meerkats do not ignore the need for security. One Meerkat always seems to be a sentry and stands guard to keep the gang safe.
There typical day consist of, they wake up early in the morning as the first rays of sun stretch across the Kalahari. The first to come out of the burrow is usually the last one in from the preceding night. This Meerkat surveys the area to make sure the coast is clear after that the others start to rise one by one from several entrances. They start by soaking up the sun to warm up there bodies from the nights sleep by facing the sun and using their stomachs as solar panels.. One may observe some digging around the entrances, this seems to be more like exercise to warm their bodies up. Then the young start to scurry around play and grooming one another, as the elders spend time grooming sunning. Once hunger starts to set in, the search for food is on. The alpha male sets the direction for the day and decide weather or not to move towards another burrow system.. Scurrying hear and there and digging here and there, but always one is on sentry. As the day goes on and the heat sets in they will stop for a rest. These rest periods are longer during the summers but so are the days. As the day cools they are off again in the afternoon in search of food. Just before sunset they will arrive at the den for the night. At this time they will commence on repairs of the den as well as well deserved grooming and giving one another affection which is really marking one another with the anal gland or cheek saliva. As the sun falls, they descend one by one into the burrow for sleep all huddled together. Lastly, they don't like the rain and will stay in their burrow and not forage for food until the rain stops.
Interestingly enough Meerkats seem to identify one another my smell rather than sight. That is why the are constantly marking one another. For instance if a Meerkat gets separated for some time and try to rejoin the gang, the gang will think it is a intruder and get in a mobbing defense stance ( mobbing is when they huddle together so to look bigger and present aggressive behavior) until they smell what they think is the unknown Meerkat. Once the sent is recognized everything is fine.

Meerkats social structure - To survive, Meerkats must live in groups for protection, as the desert presents many challenges. Each Meerkat has an important, role to perform. It was first thought Meerkats had well defined roles in their gang from being a sentry to baby sitting to foraging for food for the young. Recent studies have disprove this and actually show that hormonal changes in Meerkats influence their behavior. Also the conditions around the burrow system effect their responsibilities. When food and water is abundant more time is spent being sentries, renovating the burrow systems, relaxing and caring for the young. Some things are instinctual while others are taught to the pups by the elders. For example raising young is a learned behavior for Meerkats. If a pup is separated at birth and kept as a pet, and the pup gets pregnant. She will not know how to raise her young or teach them how to forage for food. Meerkat roles vary:
alpha male - Dominate male of the gang, has breeding rights to the alpha female. The dominate male is not necessarily decided by the largest male in the gang.
alpha female - Dominate female of the gang, all betas are subservient to her. Only one that is suppose to breed in the gang.
beta male - Subservient males will leave the gang by 3 years in search of better breeding opportunities. They are 10 months or older
beta female - Subservient females will support the alpha Meerkats. They will be driven temporally from the gang by the alpha female when she is ready to get pregnant. They will leave the gang by 3 years in search of better breeding opportunities. At 10 months or older they are at sexual maturity.
pups - Meerkat babies, 10 months or younger.
babysitter - Stays with the pups while the gang is out foraging for food. Different gang members take the responsibility different days, this is not domiated by males of females. Generally though the least hungry Meerkat will do the babysitting. The alpha female never baby-sits. This duty is for Meerkats 6 months or older.
sentry - Watches over the gang to spot danger. It is either done standing on the ground or climbing a tree or bush. Known to climb up to 30 feet in a tree to do sentry duty. This duty is not dominated by males or female. There is a sentry on watch both at the burrow system as well as when the gang is foraging for food. During times of less available food less sentry duty is done when searching for food.
excavating - Necessary to renovate burrow systems. Often Meerkats will get one behind another and work together to move sand out of the burrow system. Like how firemen would hand buckets of water to one another to put out a fire in the old days.
mentoring - A elder Meerkat will take on the responsibility of teach a pup the do's and do don'ts of being a Meerkat. This includes how to raise young, how to forage for food, and what dangers lurk about.
grooming - Meerkats like to groom one another, and in fact have a natural reflex to groom when the area where there back and tail meet is stimulated. They will remove ticks and fleas from one anther and actually eat them, though these parasites are not a normal part of the diet
play fighting - Often done by the young in the morning and to a lesser degree in the evening. Adults will also play fight. This teaches the young to fight as well puts a dominance order to the gang.
Beta males and famales often leave the gang by three years to live with different gangs or join together to form different gangs in order to increase their chances to breed. Meerkats that embark on this journey alone or in groups of two or three face great danger, as Meerkats are most vulnerable when they few in number. Sometimes Meerkats will ally themselves with one another and takeover another gang, and getting rid of the competitive alpha male and perhaps the alpha female.
The size and makeup of the meerkat community determines what duties each will have. There is usually a dominate male and female in the community although there also seems to be a second in command. I have seen a case where the alpha female was killed and the alpha male did not seem to know what to do. He had not taken on another alpha female because that would mean a female from the outside. It was felt he would at some point leave the gang in search of throwing out another alpha male from a rival gang. The alpha male is responsible for marking the territory, some of the foraging trips turn into more of scouting trips so the alpha male can mark the outer boundaries of the territory. These tend to be days of more movement and less foraging for food.
Fights happen between rival Meerkat gangs. It generally happens for two reasons. One is territory conflict. When one gang encroaches on another gangs territory. Once the two gangs come in contact with one another they group up together and fluff their fur out and jump up and down to make themselves appear bigger, also making allot of noise. This is called mobbing. Each gang is assessing the others strength. Sometimes they separating and go opposite directions other times a ferocious fight breaks out. Meerkats will kill rival gang members if they can. Also during a fight 2 or 3 Meerkats may jump on a rival biting and scratching him. It will look like a big pile of dust. During or directly after attacks, the dominant male will take a few minutes to asses the situation and decide weather there was a victory or his gang members have fled, in this case he will retreat himself. The other case happens when roaming Meerkats either solo or in small groups are looking for better breeding possibilities try to join other gangs. Mobbing occurs and they may be or may not be successful at joining the gang..
#How did the Meerkat evolve
How did the Meerkat evolve - According to Sean Doolan, they evolved from the southern tip of Africa or the Cape of Good Hope,where a type of extinct Meerkat, called the Suricata Suricatta major, has been found . The extinct Meerkat was similar to the banded mongoose. The current theory is that the Meerkat evolved from the banded mongoose. As the weather climate changed in the region, so did the Meerkats ability to survive in drier conditions.
Why the meerkat stands - Meerkats walk and run on all four, there head is only six inches above ground in this state. When they stand, their total height is 12 inches, providing them with a much better vantage point to see danger. In order to attain an even better vantage point, they will also climb trees and bushes. Their vision is good but depth perception does not appear to be as strong. They bob their head up and down to get distance measurement when objects or close. this gives them different focal points.When facing a threat, they will stand, arch their bodies and erect their tails in an attempt to appear bigger.
What threatens Meerkats? - The threats to a meerkat come from sky, land and weather. In the sky, the Martial Eagle, with a wing span of six feet, can easily prey on adults, while other smaller birds of prey prefer to snatch the young. When the winged predator is seen the alarm goes out and all sprint for nearby bolt holes. If they are not near any bolt holes the will lie on the ground and depend on camouflage They also may take cover in thorny bushes where the birds dare not venture. On the ground, the jackal and other wild cats are the Meerkats primary foe; however, when banded together, Meerkats have the ability to chase away a jackal. Badgers can also be a threat, as their burrowing can penetrate the Meerkats den making them more vulnerable prey. As mentioned previously, the cobra sometimes threatens meerkat young. Meerkats will mob a cobra relentlessly if it tries to enter their burrow. They are agile enough to avoid a snakes strike. They even have the ability to kill a cobra. If they come across one while our foraging they will temporarily mob it and once the situation is under control move on. A puff header snake will also eat Meerkat pups. I have read about a sighting in which a group of Banded mongooses actually climbed a tree to rescue one of their family members from a eagle. Both the Banded mongoose and the meerkat have similar social habits.
Meerkats are also threatened by other competitive gangs as mentioned above. The sentry's alarm will sound if another gang of Meerkats is encroaching upon marked territory. The fights are fierce but sometimes fatal as submission is the goal. The winners, usually the larger of the groups, take or keep the burrow system in question. One interesting note after the fight and Meerkats try and rejoin there gang small fight break out because they have difficulty recognizing each other by sight. The Meerkat rejoining their gang may smell like the rival gang. After the conflict, the winners will hug and congratulate each other with human-like gestures, this is rely remarking each other.. Often non-dominant Meerkats defect from the losing group to the winner's side.
The summer rains also threaten the Meerkats. When rain approaches, the sentry sends the alarm off. As there are often newborns during this time, they must make sure the are on high ground so to avoid a flooding of the burrow system. The alpha female will transport the young one by one to the higher ground burrow. At night they may get stuck in a flooding burrow system.
The most famous of all Meerkats - There are two famous Meerkats that should be mentioned One is Timone, who was featured in the Lion King. Timone, the cartoon character, is based on the real-life Meerkat Timone who which is domesticated resides outside of Palm Springs, California at the only private refuge for Meerkats in existence. For more information, visit www.meerkats.com. You can actually go and visit Timone and hand feed other Meerkats there. I did and it was a terrific experience.
The second is Ziziphus of the Lazuli gang. She is a wild Meerkat and lives in the Kalahari and has been the subject of numerous documentaries and films. One of her more prominent projects is Walking With Meerkats which is a National Geographic documtory filmed in 2000.
Meerkat communication - Meerkats constantly communicate with one another in three different ways: scent, sound, and body language. There have over 20 different sounds that have been recorded which have different meanings. These calls can be broken down into six different groups: lost calls, alarm calls, leading the group calls, pup feeding calls, guarding calls, and foraging calls. For example, while out looking for food, they are are constantly communicating in what sounds like a kind of growling. It helps them to keep track of one another's location since they forage up to 15 feet (5 meters) apart. When the young are learning how to forage, they are very loud and can be heard up to a hundred yards away. If they become separated from the adults, the volume of their cries increases so that an adult will come to get them. They have numerous sounds that are used when grooming and playing
When on guard duty, there is an entirely different assortment of sounds employed. These sounds are constant and communicate to everyone else what is happening during the watch. When everything is fine, the sentry emits mellow tones. When a predator is spotted at a distance, a beeping sound is given, almost like a yellow alert. If the predator gets closer, the sound differentiates depending on the type of predator. The martial eagle tends to get the most frantic alarm even from great distance. Meerkats allow some predators to get very close before they sound the red alert (up to 100 feet from the den).
One last interesting point, sound can be broken up into one, two, three, and even four syllable calls.
How the seasons effect Meerkats -
In the Savanna desert, temperatures can vary greatly. Remember, Meerkats live on southern hemisphere as opposed to the United States and Europe which are on the northern hemisphere. South of the equator and the seasons are opposite of those in the northern hemisphere. The Kalahari summer is considered the wet season, . The summer months October to April temperature can reach 115 (f) or around 40 (c) which can give a sand temperature of 158 (f) or 70(c). In this harsh environment the difference between being in the sun and shade can be up to 86 (f) or 30 (c). The winter months from May to September are very different from the summer, you will see highs around 70 (f) or 22 (c) during the short days and lows at night down below freezing to 14 (f) or -10 (c). Winter is the dry season. Because of these dramatic temperature changes, their feeding habits change accordingly
In the wet season or summer, Meerkats get up early in order to avoid looking for food in the heat. As the day gets warmer, they look for food in shaded areas. At mid-day they return to their den or find a nice, shaded spot for a mid-day nap. If they nap outside, they will lie on their belly with legs stretched out and often throw cooler sand on their back. They will pant during the summer this aids in reducing their body temperature. The yellow mongoose shares this behavior. They wake for a late afternoon feeding which ends at sunset. This season is a virtual feast for Meerkats, as the rain brings out an abundance of food and vegetation especially towards the end of summer from January to April. Grasses on the dunes can reach heights of over three feet tall! Meerkats will eat to their hearts content and their little bellies stick out.
In the dry season or winter, they wait until it warms up a little (9 a.m.) to go and look for food. No mid-day naps at this time. They stay out all day and get back around 4:30 p.m. Meerkats then remain in their den to avoid the rapid and severe temperature change night brings. Food is not as abundant during this time and foraging for food is more difficult. They have to do allot more digging and cover more territory to find adequate nutrition. They will also eat ants, ant eggs, millipedes, and small beetles which are less appealing to them than their summer favorites of lizards, insect larvae, and scorpions.
Meerkats like most other living creatures change their behavior patterns as conditions change. As one reads about the charertistics of any animal you must know whether the animal was observed in captivity or in the wild. Unfortunately most of what has been written about Meerkats has been in captivity, because of the remote habitat where they live makes it hard reach. Therefor it is interesting to understand how their behavior changes when confined to zoos.
The gang will find many differences in captivity. For example food will be abundant and the normal procurement of food such as digging is not necessary. Also space is significantly limited. So the Meerkats will not migrate from burrow to burrow, but stay in one burrow system. They also are not able to forage for food keeping them within meters of there burrow system for their whole lives. Predators are non existent in captivity so there alert systems are dulled. In captivity one will find Meerkats living longer and bigger. Meerkats do fine in captivity, in fact for the Meerkat which spends most of its time looking for food in the wild, this is probably a vacation. In captivity Meerkats are known to mate up to twice a year while in the wild they only mate once a year. Their cuisine is quite different to. In captivity the keepers may feed mice, worms and other sorted insects locally available. A Scorpion, a Meerkat delight would never be seen. Meerkats that don't get along with the gang will be separated and put in another habitat.
Would Meerkats make good pets? - The answer to this question is no, not really. In the United States, you need special permits to keep these animals. The government mandates strict specification for Meerkats enclosures as well as their climate. Meerkats will think your family is their gang and the are the alpha. When you have guest to your home they will get aggressive towards them. A host of other animals would make more appropriate pets! I have run into many people in southern part of Africa that keep Meerkats as pets and say they can be friendly. They are terrific pets though if you have a scorpion infestation problem.
This is a stack of four one-minute exposures of the Hapuna Prince Beach Resort, making for a total of four minutes of effective open shutter time spread out over about eight minutes of actual time.
The subject doesn't really lend itself to long duration exposure. I was mostly curious to see if I could average out some of the motion of the clouds as well as the water. I think I would need to use more exposures spread out over more time. The clouds just weren't moving that fast.
The funny thing is, the winter surf was quite good, and there were easily a hundred people in the water with boogie boards. Only one stood still long enough to show up. Sort of.
Bear with me as I get used to using this filter. I don't think I've found a good subject yet. I'm still working out the technique.
en.wikipedia.org/wiki/Spring_(season)
Definition
Meteorologists generally define four seasons in many climatic areas, winter, spring, summer and autumn (or fall). These are demarcated by the values of their average temperatures on a monthly basis, with each season lasting three months. The three warmest months are by definition summer, the three coldest months are winter, and the intervening gaps are spring and autumn. Spring, when defined in this manner, can start on different dates in different regions. In most of Northern Hemisphere locations, spring occurs during the months of March, April and May[1]. (Summer is June, July, August; Autumn is September, October, November; Winter is December, January, February.) The vast majority of Southern Hemisphere locations will have opposing seasons with spring in September, October and November.[2]
Astronomically, the vernal equinox (usually 20 March in the Northern Hemisphere, and 22 September in the Southern Hemisphere), should be the middle of spring (based on the angle of the sun and insolation) and the summer solstice (usually 21 June in the Northern Hemisphere and 21 December in the Southern Hemisphere) should be mid-summer (because the sun is at its highest) but daytime temperatures lag behind insolation by several weeks because the earth and sea have thermal latency and take time to warm up.
Some cultures, such as those who devised the Celtic and East Asian calendars, call the spring equinox mid-spring, but others (especially in the USA and sometimes in England) regard it as the "first day of spring". For most temperate regions, signs of spring appear long before the middle of March, but the folklore of 21 March being the "first day of spring" persists, and 21 June as the "first day of summer" is common in the USA. In South Africa, Australia and New Zealand, spring begins on 1 September, and has no relation to the vernal equinox.[3]
In East Asian Solar term, spring begins on 4 February and ends on 5 May. Similarly, according to the Celtic tradition, which is based solely on daylight and the strength of the noon sun, spring begins in early February (near Imbolc or Candlemas) and continues until early May (Beltane).
The phenological definition of spring relates to indicators, the blossoming of a range of plant species, and the activities of animals, or the special smell of soil that has reached the temperature for micro flora to flourish. It therefore varies according to the climate and according to the specific weather of a particular year.
Events
In spring, the axis of the Earth is increasing its tilt toward the Sun and the length of daylight rapidly increases for the relevant hemisphere. The hemisphere begins to warm significantly causing new plant growth to "spring forth," giving the season its name. Snow, if a normal part of winter, begins to melt, and streams swell with runoff. Frosts, if a normal part of winter, become less severe. Temperate climates have no snow and rare frosts, the air and ground temperature increases more rapidly. Many flowering plants bloom this time of year, in a long succession sometimes beginning even if snow is still on the ground, continuing into early summer. In normally snowless areas "spring" may begin as early as February (Northern Hemisphere) heralded by the blooming of deciduous magnolias, cherries, and quince, or August (Southern Hemisphere) in the same way. Subtropical and tropical areas have climates better described in terms of other seasons, e.g. dry or wet, or monsoonal, or cyclonic. Often the cultures have locally defined names for seasons which have little equivalence to the terms originating in Europe. Many temperate areas have a dry spring, and wet autumn (fall), which brings about flowering in this season more consistent with the need for water as well as warmth. Subarctic areas may not experience "spring" at all until May or even June, or December in the outer Antarctic.
While spring is a result of the warmth caused by the turning of the Earth's axis, the weather in many parts of the world is overlain by events which appear very erratic taken on a year-to-year basis. The rainfall in spring (or any season) follows trends more related to longer cycles or events created by ocean currents and ocean temperatures. Good and well-researched examples are the El Niño effect and the Southern Oscillation Index.
Unstable weather may more often occur during spring, when warm air begins on occasions to invade from lower latitudes, while cold air is still pushing on occasions from the Polar regions. Flooding is also most common in and near mountainous areas during this time of year because of snowmelt, accelerated by warm rains. In the United States, Tornado Alley is most active this time of year, especially since the Rocky Mountains prevent the surging hot and cold air masses from spreading eastward and instead force them into direct conflict. Besides tornadoes, supercell thunderstorms can also produce dangerously large hail and very high winds, for which a severe thunderstorm warning or tornado warning is usually issued. Even more so than in winter, the jet streams play an important role in unstable and severe weather in the springtime in the Northern Hemisphere.
In recent decades season creep has been observed, which means that many phenological signs of spring are occurring earlier in many regions by a couple of days per decade.
Spring is seen as a time of growth, renewal, of new life (both plant and animal) being born. The term is also used more generally as a metaphor for the start of better times, as in the Prague Spring. Spring in the Southern Hemisphere is different in several significant ways to that of the Northern Hemisphere. This is because: there is no land bridge between Southern Hemisphere countries and the Antarctic zone capable of bringing in cold air without the temperature-mitigating effects of extensive tracts of water; the vastly greater amount of ocean in the Southern Hemisphere at all latitudes; at this time in Earth's geologic history the Earth has an orbit which brings it in closer to the Southern Hemisphere for its warmer seasons; there is a circumpolar flow of air (the roaring 40s and 50s) uninterrupted by large land masses; no equivalent jet streams; and the peculiarities of the reversing ocean currents in the Pacific.
