This specie and the Ground Squirrels provide for my amusement when the birding gets slow at our pond. These rodents know every nook and cranny of the jumbled rock and log border surrounding the pond, and can navigate through this maze with amazing dexterity and speed. It's their "jungle gym." and safe house! I have to constantly watch them through my viewfinder to quickly capture a still moment like this... they're usually in frantic motion. This one has paused to munch on scattered bird seed.

I observed the strangest behavior I've ever had the privilege of witnessing. I spotted a Great Blue Heron motionless waiting for fish. I noticed something on its back and realized a Red-wing Blackbird was sitting on him. The Blackbird then began frenzied pecking at the heron's back. Nonplussed the heron never moved. The Blackbird then began flying up and landing on the Heron repeatedly. I estimate about a dozen times. The Heron eventually caught a fish which it ate. Then it started to stalk about with the Blackbird on its back. The strangest and most amazing interaction I have ever seen.

Potoos are nocturnal insectivores which lack the bristles around the mouth found in the true nightjars. They hunt from a perch like a shrike or flycatcher. During the day they perch upright on tree stumps, camouflaged to look like part of the stump. The single spotted egg is laid directly on the top of a stump. The mother sits in a cryptic pose with the chick on top of the stump.
I took this picture while on a photo tour led by Jeff Munoz of Rainforest Photo Tours (rainforestphototours.com).
This view serves to distinguish that this is a female Broad-tailed Hummer. It's late enough for the female juvies to be flying... both sexes initially look much like Mom. I believe this one to be an adult female. We need to do this close examination only in summer when the Rufous migrants are passing through. There is no rufous is the facial area. The throat area is a clean finely streaked white. The tail pattern of this bird shows rufous only on the outer retrices. It's not always easy to capture the ideal view... if uncertain re a bird's ID I take multiple shots of the same bird (if it cooperates) to make its ID task a little easier for me. Until late June, however, this is the only Hummer species up here. The sexes of the local adult Hummers are easily distinguished.

Spotted Hyena (Crocuta crocuta) having a ferocious argument over a buffalo carcass. Waiting on the sidelines daring not to get too close are White-backed Vultures (Gyps africanus). Perhaps this is how hyenas get tattered ears. Image taken in South Luangwa National Park in Zambia.
I watch this tandem pair of Swamp Spreadwings (Lestes vigilax) quickly land on the surface of the water when a Slaty Skimmer (Libellula incesta) flew too close to them. All other times the pair would perch on emergent vegetation. Blue Heron Pond Patuxent Research Refuge, Anne Arundel County, Maryland.
This is only a small fraction of the seabirds that had assembled on the shoreline of the well-visited public beach park. If you walked slowly through the place where they were resting, the grounded flock usually parted (without flying) to create a path to let you pass through. Sometimes, however, the beachgoers' actions spooked them and they rose en masse, circling low across the area before resettling in the same spot on the beach. This behavior afforded many photo ops for close flight shots of the group, and even better yet, of individual birds. Most of these birds are Royal Terns and Elegant Terns, but I also could spot a few black bills (now out of frame to the left) that indicate Sandwich Terns.

Most bird motion of any sort is accompanied by some wing action to help them maintain their stability. This accomplished gymnast is leaping to a lower position on the rocks surrounding the pool without extending his wings... maybe showing off for the ladies?

Bad day for our male snail kite. I went out to lox for fifteen or twenty minutes today (too much thunder and lightning). THIS IS NOT GOOD PHOTOGRAPHY!!! The light was bad, and it was raining. This is to show Red winged blackbirds for the mean little SOB's they can be!
Tancho Crane/ Red-crowned Crane
The red-crowned crane (Grus japonensis), also called the Manchurian crane or Japanese crane (Japanese: 丹頂鶴 or タンチョウヅル; rōmaji: tanchōzuru), is a large East Asian crane among the rarest cranes in the world. In some parts of its range, it is known as a symbol of luck, longevity, and fidelity.
Adult red-crowned cranes are named for a patch of red bare skin on the crown, which becomes brighter during mating season. Overall, they are snow white in color with black on the wing secondaries, which can appear almost like a black tail when the birds are standing, but the real tail feathers are actually white. Males are black on the cheeks, throat, and neck, while females are pearly gray in these spots. The bill is olive green to greenish horn, the legs are slate to grayish black, and the iris is dark brown.
This species is among the largest cranes, typically measuring about 150 to 158 cm (4 ft 11 in to 5 ft 2 in) tall and 101.2–150 cm (3 ft 4 in–4 ft 11 in) in length (from bill to tail tip). Across the large wingspan, the red-crowned crane measures 220–250 cm (7 ft 3 in–8 ft 2 in). Typical body weight can range from 4.8 to 10.5 kg (11 to 23 lb), with males being slightly larger and heavier than females and weight ranging higher just prior to migration. On average, it is the heaviest crane species, although both the sarus and wattled crane can grow taller and exceed this species in linear measurements. On average, adult males from Hokkaidō weighed around 8.2 kg (18 lb) and adult females there averaged around 7.3 kg (16 lb), while a Russian study found males averaged 10 kg (22 lb) and females averaged 8.6 kg (19 lb); in some cases, females could outweigh their mates despite the males' slightly larger average body weight. Another study found the average weight of the species to be 8.9 kg (20 lb).
In the spring and summer, the migratory populations of the red-crowned crane breed in Siberia (eastern Russia), north-eastern China and occasionally in north-eastern Mongolia (i.e., Mongol Daguur Strictly Protected Area). The breeding range centers in Lake Khanka, on the border of China and Russia. Normally, the crane lays two eggs, with only one surviving. Later, in the fall, they migrate in flocks to the Korean Peninsula and east-central China to spend the winter. Vagrants have also been recorded in Taiwan. In addition to the migratory populations, a resident population is found in eastern Hokkaidō in Japan. This species nests in wetlands and rivers. In the wintering range, their habitat is comprised mainly by paddy fields, grassy tidal flats, and mudflats. In the flats, the birds feed on aquatic invertebrates and, in cold, snowy conditions, the birds switch to mainly living on rice gleanings from the paddy fields.
The population of red-crowned cranes in Japan is mostly non-migratory, with the race in Hokkaidō moving only 150 km (93 mi) to its wintering grounds. Only the mainland population experiences a long-distance migration. They leave their wintering grounds in spring by February and are established on territories by April. In fall, they leave their breeding territories in October and November, with the migration fully over by mid-December.
A red-crowned crane pair duets in various situations, helping to establish formation and maintenance of the pair bond, as well as territorial advertisement and agonistic signaling. The pair moves rhythmically until they are standing close, throwing their heads back and letting out a fluting call in unison, often triggering other pairs to start duetting, as well. As it is occurs year around, the social implications of dancing are complex in meaning. However, dancing behavior is generally thought to show excitement in the species. To strengthen the bond, red-crowned cranes engage in dual honking rituals before performing a dance.
The estimated total population of the species is only 2,750 in the wild, including about 1,000 birds in the resident Japanese population. Of the migratory populations, about 1,000 winter in China (mainly at the Yellow River delta and Yancheng Coastal Wetlands), and the remaining winter in Korea. It received endangered status on June 2, 1970.
In Japan, this crane is known as the tanchōzuru and is said to live for 1,000 years. A pair of red-crowned cranes was used in the design for the Series D 1000-yen note (reverse side). In the Ainu language, the red-crowned crane is known as sarurun kamuy or "marsh-kamuy". At Tsurui, they are one of the 100 Soundscapes of Japan. Cranes are said to grant favours in return for acts of sacrifice, as in Tsuru no Ongaeshi ("crane's return of a favor").

Peter Dunn describes this Owl as "a potato on stilts." It does have long legs, and makes them appear even longer as it stretches upward to better view its surroundings. Locally it is found in prairie dog colonies where it shares the rodents' burrows. While it can excavate its own dwelling (e.g. in FL), it's no dummy, and saves this needed energy for other essential activities. By the accumulated scat you can surmise that this is a favored burrow site.

This is a bit less about people and more about how they live and the way we can project our own behavior on almost anything we see and then identify with it ;)
Stingrays are not uncommon along Tybee Island, but stings are rare.
Stingrays lay on the bottom, partly burring under the sand. When stepped on, they will whip their tail up and stab the offender with their barb. It is a defensive behavior. Always shuffle your feet on the sand bottom when wadding in the water. This way, you will alert the ray of your presence and it may scare them off. Teach young ones to shuffle their feet and never "walk" as if on land.
Stingray injuries may occur when fishing or wadding. The barb is located on the tail, and is stabbed into the victim as a defensive maneuver. Laceration type wounds may require stitches. A tetanus shot may also be required. Should shock symptoms develop, or barb is embedded in tissue, the victim will require EMS & hospital treatment. Never pull out a barb deeply embedded in tissue, chest or abdomen areas, which can be very serious.
Rays are edible, and may be caught as food using fishing lines or spears. Stingray recipes abound throughout the world, with dried forms of the wings being most common. For example, in Singapore and Malaysia, stingray is commonly grilled over charcoal, then served with spicy sambal sauce. Generally, the most prized parts of the stingray are the wings (flaps is the proper terminology), the "cheek" (the area surrounding the eyes), and the liver. The rest of the ray is considered too rubbery to have any culinary uses.
While not independently valuable as a food source, the stingray's capacity to damage shell fishing grounds can lead to bounties being placed on their removal.

Head pressure, medically referred to as intracranial pressure, is pressure between the skull and the brain. Too much pressure in the head can restrict blood flow to the brain and press on structures in the brain. It is a serious medical condition that has the potential to cause severe damage to the brain or spinal cord. Contact your doctor if you experience pressure in the head. Symptoms of abnormal head pressure include lethargy, behavior changes, headache, seizures and vomiting.Even though it is tempting to think of our energy body as a sort of plumbing system with tubes and vents, the reality is completely different. Our energy system is more like clouds of gases that merge and mingle and sometimes cramp up. Or even better, you can imagine it as different coloured streams of water that weave and intermingle and sometimes freeze into ice. These different coloured water streams are our thoughts and emotions and when we try to suppress these thoughts and emotions they “freeze“ and we experience them as “blocks“ in our mind and body.he head chakras (forehead and crown) have to do with the mental part of our being which consists of our thoughts, concepts and beliefs on the intellectual and spiritual levels. When we experience head pressure we are literally suppressing certain thoughts that we do not want to think. It is this suppression that we experience as the head pressure and it happens completely unconsciously. People without kundalini also often unconsciously suppress certain thoughts but due to their greater unawareness they do not feel the pain of this suppression – they are more numb.In the kundalini process, a thirst awakens in us for expanded consciousness and more spirituality. However, there may be still parts of our old ego alive that do not want to have certain spiritual insights and defend themselves by rigorously suppressing ideas that challenge the old ego. So, this is the inner conflict that plays itself out in our head chakras – the fight for spiritual insights and authenticity on the one hand and the resistance of our old ego that is not yet ready to accept some humbling insights on the other.
Before I tell you what kind of thoughts people typically suppress, I need to give you a little warning. If you are a person with head pressure you will probably not like what I am about to tell you for the very reason that you have repressed these kinds of insights in the first place. But everything in this article is based on my work with hundreds of clients who had kundalini syndrome. All the clients who could take the following advice on board now have much less head pressure or none at all.
In my experience, most people with head pressure suppress self-critical thoughts. These people describe themselves as laid-back, easy going and even loving towards themselves. They do not criticise themselves and when others criticise them, they either completely ignore it or they get angry. However, in order to be a spiritually mature person, it is important that we clearly see our many flaws (without beating ourselves up about them) and then get to work to eliminate these flaws.
For people with low self-esteem, this is not difficult to do as they are usually too self-critical to start with. But it is those people who like themselves and have a high opinion of themselves who are most prone to pressure in the head chakras during the kundalini process. (If you do not like this insight, remember that I warned you!

Kundalini awakening symptoms include strange body sensations like shaking, tingling or the feeling of moving energy. On the psychologically level we often experience greatly intensified emotions and a general over-sensitivity to ‘everything’. And on the spiritual level we may experience a great increase of spiritual interest but also a lot of confusion.
The first thing that I explain to all my kundalini clients is that a kundalini awakening and its symptoms can be compared with the awakening of our sexual drive during puberty. Both processes have a lot in common.
First of all, both processes are irreversible. No matter, how much we yearn to go back to the carefree innocence of our childhood, puberty endows us with strong sexual urges that cannot be ignored. In the same way there is no going back once kundalini has made its presence known in our body and mind.
In both processes, puberty as well as kundalini awakening, we are endowed with a lot more power than we previously had. In puberty we develop the awesome power to create a new human being and during a kundalini awakening we receive powers like clairvoyance, supernatural abilities and ultimately the ability to manifest ourselves as a divine being.
But until we are able to harvest the full rewards of these newly awakened powers we have to change radically. As we all know, the transition from being a child to a happy parent usually entails many years of difficulties until we learn to channel our sex drive into loving relationships. Everything has to change during these years – our self-image, our relationships, our ability to take responsibility for our actions and generally our entire outlook on life.
In order to manage this process it is paramount to live as peacefully, lovingly and healthily as possible. Anything that could upset ourselves further like taking drugs, having promiscuous sex or experimenting on our mind with meditation without the help of an experienced kundalini teacher should be avoided.
It is good to have a spiritual outlook on life and develop trust in a divine power. But it is important not to overdo spiritual practices as they make the kundalini stronger. If you feel inclined to meditate daily it is paramount only to do this under the guidance of an experienced meditation teacher who has gone through a kundalini experience themselves.
Do ask your local meditation teacher if they have gone through this but do not be surprised if they haven’t because real kundalini awakenings are still very rare. Luckily, in the age of the internet you can also try to find a teacher online and build a trusting relationship in order to get guidance about how to meditate.
It is particularly important to avoid any form of energy healing like reiki or acupuncture. These forms of healing are devised for people who are not in a kundalini process and often do a very good job. But once we have become over-sensitive during a kundalini process these healing modalities can aggravate us severely.
A comparison with puberty can explain why this is. Imagine being upset about your emerging sexual needs and you go to an energy healer to get rid of them. It is obvious that this is doomed to fail. Our libido, as well as the kundalini, is far stronger than these approaches and we will only end up in even more suffering if we try to remove of either of them.
Another thing to avoid is breathing exercises like re-birthing or yogic breathing. Both are powerful ways to alter our body and brain chemistry and can have disastrous consequences if used even slightly in the wrong way. Breathing exercises can be compared with prescription drugs. They should only be used when administered by a skilful physician and certainly not to someone who is seriously challenged by a kundalini process.
I have had many kundalini clients who read all sorts of horror stories on the internet and were very afraid. It is this fear that makes kundalini symptoms far worse than they need be. Just think of how a teenage girl would feel who is repeatedly told that there is the risk of being murdered by her own husband. While this may be true in extremely rare cases, it is not helpful to frighten young people in this way.
The same can be said about kundalini. In rare cases people may deal with it so badly that they end up in a very painful place. But in order for this to happen a lot of negative factors have come together and it is not useful to frighten yourself with these ideas on top of the challenges that kundalini entails anyway. So I strongly advise people to stay away from reading any frightening material about kundalini.
A kundalini awakening is a very individual and personal process, just like the development of a satisfying sexuality after puberty is a very personal process. People usually benefit a great deal from personal guidance in both processes.
For a kundalini awakening, you need an experienced spiritual teacher who has gone through this process themselves – just like all youths need guidance about sexuality and relationships from someone who has mastered these areas themselves.
People also benefit from guidance about how to deal with their budding clairvoyance, which can be very confusing and frightening for the unprepared mind. However, the biggest challenge is always the very personal material that emerges from one’s unconscious mind during this process, requiring personal advice.
Finally, it is paramount to adjust your spiritual practices to accommodate the kundalini so that it flows calmly and steadily and does not erupt in fits and starts. In order to do this, you need a personal relationship to a kundalini teacher who can guide you in this way.
Cape Baboons in the Upper Thendele Camp
Bärenpaviane im Upper Thendele Camp
(Wikipedia)
The chacma baboon (Papio ursinus), also known as the Cape baboon, is, like all other baboons, from the Old World monkey family. It is one of the largest of all monkeys. Located primarily in southern Africa, the chacma baboon has a wide variety of social behaviors, including a dominance hierarchy, collective foraging, adoption of young by females, and friendship pairings. These behaviors form parts of a complex evolutionary ecology. In general, the species is not threatened, but human population pressure has increased contact between humans and baboons. Hunting, accidents, and trapping kill or remove many baboons from the wild, thereby reducing baboon numbers and disrupting their social structure.
Due to hybridization between different baboon (Papio) populations across Africa, authors have occasionally grouped the entire radiation as a single species, the hamadryas baboon, Papio hamadryas. Arbitrary boundaries were then used to separate the populations into subspecies. Other authors considered the chacma baboon a subspecies of the yellow baboon, Papio cynocephalus, though it is now recognised as a separate species, Papio ursinus. The chacma baboon has two or three subspecies, depending on which classification is followed. Grubb et al. (2003) listed two subspecies,[4] while Groves (2005) in Mammal Species of the World listed three. This article follows Groves (2005) and describes three distinct subspecies. In the Grubb et al. (2003) paper, P. u. raucana was believed to be synonymous with P. u. ursinus.
Papio ursinus ursinus Kerr, 1792 – Cape chacma (found in southern South Africa)
P. ursinus griseipes Pocock, 1911 – Gray-footed chacma (found in northern South Africa to southern Zambia)
P. ursinus raucana Shortridge, 1942 – Ruacana chacma (found from Namibia to southern Angola, but not accepted by all authorities as distinct.
The chacma baboon is perhaps the longest species of monkey, with a male body length of 50–115 cm (20–45 in) and tail length of 45–84 cm (18–33 in). It also one of the heaviest; the male weighs from 21 to 45 kg (46 to 99 lb) with an average of 31.8 kg (70 lb). Baboons are sexually dimorphic, and females are considerably smaller than males. The female chacma weighs from 12 to 25 kg (26 to 55 lb), with an average of 15.4 kg (34 lb). It is similar in size to the olive baboon, averaging slightly higher in mean body mass, and of similar weight to the more compact mandrill, the males of which weigh on average about 1 kg (2.2 lb) more than a chacma baboon, the females weigh 3 kg (6.6 lb) less than the female chacma. While the mandrill is usually crowned the largest of all modern monkeys, going on total length and average (but not maximum) body weight between the sexes, the chacma baboon appears to be the largest extant monkey. The chacma baboon is generally dark brown to gray in color, with a patch of rough hair on the nape of its neck. Unlike the males of northern baboon species (the Guinea, hamadryas, and olive baboons), chacma males do not have a mane. Perhaps the most distinctive feature of this baboon is its long, downward-sloping face. The canine teeth of male chacma baboons have a mean length of 3.86 ± 0.30 cm (1.52 ± 0.12 in) at the time they emigrate from their natal troop. This is the time of greatest tooth length as the teeth tend to wear or be broken thereafter.
The three subspecies are differentiated by size and color. The Cape chacma is a large, heavy, dark-brown, and has black feet. The gray-footed chacma is slightly smaller than the Cape chacma, lighter in color and build, and has gray feet. The Ruacana chacma generally appears to be a smaller, less darkly colored version of the Cape chacma.
The chacma baboon inhabits a wide array of habitats including woodland, savanna, steppes, and subdesert, from the grassy alpine slopes of the Drakensberg to the Kalahari desert. During the night the chacma baboon needs hills, cliffs, or large trees in which to sleep. During the day water availability may limit its range in arid areas. It is found in southern Africa, ranging from South Africa north to Angola, Zambia, and Mozambique. The subspecies are divided across this range. The Cape chacma is found in southern South Africa; the gray-footed chacma, is present from northern South Africa, through the Okavango Delta in Botswana, Zimbabwe, Mozambique (south of the Zambezi), to southwest Zambia; and the Ruacana chacma is found in northern Namibia and southern Angola.
The chacma baboon is omnivorous with a preference for fruits, while also eating insects, seeds, grass, smaller vertebrate animals, and fungi (the desert truffle Kalaharituber pfeilii); at the Cape of Good Hope in particular, it is also known for taking shellfish and other marine invertebrates. It is generally a scavenger when it comes to game meat, and rarely engages in hunting large animals. One incident of a chacma baboon killing a human infant has been reported, but the event is so rare, the locals believed it was due to witchcraft. Normally, chacma baboons will flee at the approach of humans, though this is changing due to the easy availability of food near human dwellings.
The chacma baboon usually lives in social groups, called troops, which are composed of multiple adult males, adult females, and their offspring. Occasionally, however, very small groups form that consist of only a single adult male and several adult females. Chacma troops are characterized by a dominance hierarchy. Female ranking within the troop is inherited through the mother and remains relatively fixed, while male ranking is often in flux, especially when the dominant male is replaced. Chacmas are unusual among baboons in that neither males nor females form strong relationships with members of the same sex. Instead, the strongest social bonds are often between unrelated adult males and females. Infanticide is also common compared to other baboon species, as newly dominant males will often attempt to kill young baboons sired by the previously dominant male. Baboon troops possess a complex group behavior and communicate by means of body attitudes, facial expressions, vocalizations and touch.
The chacma baboon often sleeps in large groups on cliffs or in trees at night to avoid predators. The morning dispersal from the sleeping site is synchronized, with all members leaving at the same time. In most cases, dispersal is initiated by a single individual, and the other members of the group decide whether or not to follow. At least five followers must be recruited for a successful dispersal initiation, and not all initiation attempts are successful. Surprisingly, the initiator's dominance status shows little correlation with successful initiation of departure; more-dominant individuals are no more likely to lead a successful departure than subordinate individuals. One study has shown that while the success rate of dispersal initiation attempts is relatively constant across all sexes, male are more likely to attempt initiation than females, and lactating females are less likely to attempt initiation than females without dependent offspring. A separate study has achieved slightly different results. While dominance hierarchy does not play a significant role in initiating the morning dispersal, social affiliation does. Chacma baboons that play a more central role in the group (as measured by grooming behavior and time spent with other members) are more likely to be followed during the morning dispersal. This study concluded that group members are more likely to follow the behavior of individuals with which they are closely affiliated.
Dominance does play a role in group foraging decisions. A dominant individual (usually the alpha male) leads the group to easily monopolized resources. The group usually follows, even though many subordinate members cannot gain access to that particular resource. As in morning dispersal, the inclination of group members to follow the leader is positively associated with social interactions with that dominant individual.
Collective foraging behavior, with many individuals taking advantage of the same resource at once, has also been observed. However, this behavior can be chiefly attributed to shared dietary needs rather than social affiliation. Pregnant females, who share similar dietary needs, are more likely to synchronize their behavior than fertile females. Foraging synchronization decreases in areas with lower food density.
Adoption behavior has been observed in chacma baboons. Orphaned baboons whose mothers have disappeared or died are often too small to care for themselves. In one study of nine natural orphans and three introduced orphans, all but one orphan were adopted by another member of the group. The individual that was not adopted was 16 months old, four months older than the next oldest orphan, and was old enough to survive on its own. Adoption behavior includes sleeping close to the orphaned infant, grooming and carrying the orphan, and protecting it from harassment by other members of the troop. Both males and females care for infants, and care does not depend on the infant's sex. Additionally, all caregivers are prereproductive, only four or five years of age. The two major theories explaining this behavior are kin selection, in which caregivers take care of potentially related orphans, and parental practice, in which young caregivers increase their own fitness by using an orphan to practice their own parental skills.
Males and female chacma baboons often form relationships referred to as "friendships". These cooperative relationships generally occur between lactating females and adult males. The females are believed to seek out male friendships to gain protection from infanticide. In many baboon species, immigrant alpha males often practice infanticide upon arrival in a new troop. By killing unrelated infants, the new male shortens the time until he can mate with the females of the troop. A female with dependent offspring generally does not become sexually receptive until she weans her offspring at around 12 months of age. However, a mother usually becomes sexually receptive shortly after the death of her offspring.
This protection hypothesis is supported by studies of stress hormones in female baboons during changes in the male hierarchy. When an immigrant male ascends to the top of the male dominance hierarchy, stress hormones in lactating and pregnant females increases, while stress hormones in females not at risk of infanticide stay the same. Additionally, females in friendships with males exhibit a smaller rise in stress hormones than do females without male friends.
The benefits of friendship to males are less clear. A male is more likely to enter into friendships with females with which he has mated, which indicates males might enter into friendships to protect their own offspring and not just to protect that female's future reproductive success. These friendships may play a role in the mating system of chacma baboons. A female will often mate with several males, which increases the number of potential fathers for her offspring and increases the chances she will be able to find at least one friend to protect her infants.
Female chacma baboons have been observed to compete with each other for male friends. This may be the result of one male having a high probability of paternity with multiple females. These competitions are heavily influenced by the female dominance hierarchy, with dominant females displacing subordinate females in friendships with males. Generally, when a more-dominant female attempts to make friends with an individual which is already the friend of a subordinate female, the subordinate female reduces grooming and spatial proximity to that male, potentially leaving her offspring at higher risk of infanticide.
The chacma baboon is widespread and does not rank among threatened animal species. However, in some confined locations, such as South Africa's Southern Cape Peninsula, local populations are dwindling due to habitat loss and predation from other protected species, such as leopards and lions. Some troops have become a suburban menace, overturning trash cans and entering houses in their search for food. These troops can be aggressive and dangerous, and such negative encounters have resulted in hunting by frustrated local residents. This isolated population is thought to face extinction within 10 years.
The chacma is listed under Appendix II of CITES as it occurs in many protected areas across its range. The only area in South Africa where they are monitored is in the Cape Peninsula, where they are protected.
Observations by those working hands-on in South Africa's rehabilitation centers have found this species is damaged by human intervention; troop structures are influenced, and over the years a significant loss in numbers has occurred. Because they live near human habitats, baboons are shot, poisoned, electrocuted, run over, and captured for the pet industry, research laboratories and muthi (medicine).[32] Despite this, assessors working for the IUCN believe there are no major threats that could result in a range-wide decline of the species.

Der Bärenpavian oder Tschakma (Papio ursinus) ist eine Primatenart aus der Gattung der Paviane innerhalb der Familie der Meerkatzenverwandten (Cercopithecidae). Er lebt im südlichen Afrika.
Mit einer Kopfrumpflänge von bis zu 115 Zentimetern, wozu noch ein bis zu 71 Zentimeter langer Schwanz kommt, und einem Gewicht von 15 bis 31 Kilogramm bilden sie die größte und schwerste Pavianart. Ihr Fell ist an der Oberseite dunkelbraun oder grau gefärbt, die Unterseite ist heller, die Hände und Füße sind meist schwarz. Die langgezogene, unbehaarte Schnauze ist dunkelviolett oder schwarz gefärbt, ebenso die Sitzschwielen. Die Fellfärbung und die Größe sind nach Region variabel, so gibt es eine Population mit grauen Pfoten; besonders kleine Exemplare kommen zum Beispiel in der Kalahari vor.
Die Männchen sind deutlich größer und schwerer als die Weibchen und haben auch längere Eckzähne, im Gegensatz zu den übrigen Pavianarten fehlt ihnen aber die Mähne an den Schultern und am vorderen Rücken.
Bärenpaviane leben im südlichen Afrika, genauer in Angola, Botswana, Mosambik, Namibia, Südafrika und Sambia. Sie bewohnen sowohl Steppen und Savannen als auch offene Waldgebiete, sind jedoch auf das Vorhandensein von Wasser angewiesen.
Wie alle Paviane leben sie in Gruppen, meistens in gemischten Gruppen, in manchen Regionen (zum Beispiel im gebirgigen Südafrika) dominieren jedoch die Einmännchengruppen (siehe Gruppenverhalten der Paviane). Die Bärenpaviane zeigen ein komplexes Gruppenverhalten und kommunizieren mittels Körperhaltungen, Gesichtsausdrücken, Lauten und durch Körperkontakte. Bärenpaviane sind Allesfresser; sie haben eine Vorliebe für Früchte, nehmen jedoch auch Blätter, Insekten, Samen und kleinere Wirbeltiere zu sich.
Die Fortpflanzung kann das ganze Jahr über erfolgen, die Weibchen weisen während der fruchtbaren Phase eine ausgeprägte Regelschwellung auf. Innerhalb der gemischten Gruppen kann sich prinzipiell jedes Männchen mit jedem Weibchen paaren. Das führt zu teilweise erbitterten Auseinandersetzungen unter den Männchen um das Paarungsvorrecht.
Nach einer rund 180-tägigen Tragzeit bringt das Weibchen meist ein einzelnes Jungtier zur Welt, das zunächst schwarz gefärbt ist. Mit rund einem Jahr werden die Jungen entwöhnt, mit drei bis fünf Jahren tritt die Geschlechtsreife ein. Das Höchstalter eines Tieres in menschlicher Obhut betrug 45 Jahre, in freier Wildbahn ist die Lebenserwartung deutlich geringer.
Bärenpaviane sind weit verbreitet und zählen nicht zu den bedrohten Tierarten. Manchmal gelten sie als Plage, da sie Plantagen verwüsten.
In Uitenhage war in der zweiten Hälfte des 19. Jahrhunderts ein Bärenpavian namens Jack Assistent eines körperbehinderten Streckenwärters.

3/4 This behavior is the way miniature highland cows play. As a volunteer, standing at the same fence I showed you yesterday, I was reassuring younger children that the cows were not trying to hurt each other; they were wrestling the way people do.
Some of the older kids were cheering for the bovines. "Fight! Fight! Fight!" I often think "lower" life forms can be more civilized than humans.
Clark's and Western Grebes perform a "dancing on water" (technically called rushing) ritual as part of their courting behavior. Before the grebes dance, they get low in the water, and face to face (ratchet pointing). They also splash water with their beaks (dip shaking). Klamath Falls, Oregon. 5/2019.
