Ebony Jewelwing (Calopteryx maculata) female and male behaviour (teaser).
Backus Woods, Norfolk County, Ontario, Canada.

Please view full screen for best quality. ;-)
I'm editing several interesting clips together, but wanted to share this one short clip right away. ;-)
Ebony Jewelwings have very sophisticated courtship and ovipositing rituals. Females line the stream banks to watch males "joust" for their attention. FEMALES pick their partner based on these competitions. That's rare in the dragon-damselfly world. Typically, the male literally grabs a female by the scruff of her neck and hope she cooperates! @@
The reason these jousting sessions are so important to the females is because the males "hover guard" the female they mated with, to ensure that HIS progeny's eggs are safely laid in the stream (they lay their eggs on partially submerged logs, twigs or leaves.) She depends on the male's ability to stand guard while she lays her eggs.
Ebony Jewelwings (Calopteryx maculata) prefer relatively clear, fast-moving streams. The male sentry butts heads and chases away any other male that tries to interfere while she's laying her (HIS) eggs underwater (their nymphs are aquatic). I got video of that behaviour too, but I'll save that for later.
This sneak preview is something I've never seen before. A rival male managed to slip past the hover-guarding male and tossed the egg-laying female right off her log!!
I always thought the competing male would just want to mate, but he seems to be more interested in interrupting the egg-laying process.
These beautiful and fascinating creatures never cease to amaze! ❤

Why everybody must be blonde?
Today all the girls want to be blonde and blue eyed.
Blame it to the stereotypes of Capitalism and its
famous icon of Barbie Girls like that vulgar singer
called Lady Gaga (if you don´t have noticed yet,
all in her is fake, starting from her fake blue eyes,
and ending to her platinum dyed hair). But there
was a time, in the early 30´s , where all the girls
want to have dark hair, like Betty Boop, a cartoon
character created in 1930 during the great depresion.
Betty was the first sex symbol, and was not made of
flesh and blood hahaha. Many years before Marilyn
Monroe and Rita Hayworth she wore short dresses,
high heels, a garter belt, and a generous neckline :P
Someting very revolutionary for the rancind moral of that
age where all the good girls girls must be at home cleaning
their houses, cooking, taking care of their children and pleasing
their men. That´s the reason I´ve always found Betty very funny
(add this that in the first sketches that Max Fleischer draw
Betty looked like a French poodle :D). Forgot to say that Betty
character was inspired by the "Flapper girls", who loved Jazz music,
short haircuts (garçonne style) and have a rebel behaviour
against men and s society :D
THE MEANING OF LIFE
Just a bit of Philosophy, and
sometimes a little bit of irony.
Photographs that sometimes
are chained with others. Play
with them jumping from one
picture to another like If you
were playing hopscotch.
P.S. Dear voyeur (presumed dumb) :P
many thanks for your indiference about my art :P
and dear thief (presumed with more snout
than a tapir :P), Please do not use my photographs,
paintings, drawings, cartoons, poems, translations

¿Por qué todo el mundo tiene que ser rubio?
Hoy en día todas las chicas quieren ser rubias y tener los
ojos azules. Echenle la culpa al Capitalismo y a sus famosos
iconos de Chicas Barbies, como la vulgar Lady Gaga (por si
aún no sea han dado cuenta, todo en ella es falso, empezando
por el falso azúl de sus ojos y terminando por su pelo teñido de
rubio platino). Pero hubo un tiempo, en los años treintas, en que
todas las chicas querían tener los cabellos oscuros, como Betty
Boop, un personaje de comic creado en 1930 durante la gran
depresión. Betty fue el primer símbolo sexual y no era de carne
y hueso, jajaja, muchos años antes que Mrilyn Monroe y Rita Hayworth,
ella ya lucía vestido cortos, tacones altos, liguero y un generoso
escote :P Algo muy revolucionario para la rancia moral de aquella
época, que defendía que las chicas buenas tenían que quedarse
en casa, limpiando, cocinando, cuídando de sus hijos, y satisfaciendo
a sus hombres. Esa es la razón por la que siempre he encontrado a
Betty muy divertida (añandanle a eso, que en los primeros bocetos
que dibujo Max Fleischer, ella tenía forma de caniche francés :D).
Olvidé decir que el personaje de Betty estaba inspirado en las
"chicas flapper", que escuchaban música Jazz, llevaban el pelo corto
(a lo garçon, o sea, a lo chico), y tenían un comportamiento rebelde
contra los hombres y la sociedad :D

My first Barbican 'assignment' today! After work, my friend Charlotte and I headed over to the Barbican kitchen for some dinner, and then went to the Curve gallery to watch Ann Van den Broek's Loops of Behaviour. It was properly dark in there, so rather challenging, but there were lots of cool projections, and little mini stages outlined with light, which made for some interesting shots. I took over 200! Thankfully the majority were a bit rubbish, so it was easy enough to narrow down the selection.
To be honest, I thought it was all a bit arty farty to start with, but I did get into it after a while - and I certainly enjoyed photographing it. This was a private view ahead of it opening to the public; photography was generally not allowed, so I was given a special pass :)
Char and I stayed for a beer at the end. We ended up chatting to a dance photojournalist for a while, and then I met the woman I've been corresponding with at the Barbican. Had a quick chat with her, then headed home and Tim met me at the station.
Breeding behaviour
Where possible, the birds excavate a nesting burrow into the soil. Sometimes they will make use of Manx shearwater or rabbit burrows. Where burrowing is not possible, the birds nest under boulders or in cracks and cavities in cliffs.
The birds defend the nesting site and its immediate surround, and use it in subsequent years. Puffins lay only a single egg, in late April or early May. Both parents incubate it for 36-45 days, and they share the feeding duties until the chick is ready to fledge.
The fledging period is very variable, ranging from 34 to 60 days, depending on the area and year.
Adult birds desert their young shortly before they are ready to leave the nest. The timing of the breeding in puffin colonies is highly synchronised, and so the departure of all adults takes place within a few days.
The young birds leave their nest burrow and make their way to the sea, normally under cover of darkness to avoid predators. In some colonies, for instance in Iceland, nearby bright lights confuse the young birds, which then fly into the light and end up on city streets.
Puffins usually reach breeding age at 5-6 years old, and often live for 20 years.

This is a metal and vinyl backed post card sized...thing I got at the 'antique mall' last weekend. It said "Indian public service cards" and came with that round thingy to hang it up with. I'm thinking the 'behaviours' are:
Sneezing or barfing at the dinner table, or possibly bulemia
Killing small animals while your sibling possibly falls in the river and drowns
Tripping a friend while playing ball in the street causing heinous vehicular injury
Beating up the kid you just played Texas Hold'em for lunch money and lost to
Dropping your leftover sugary cereal milk off the balcony and giving one of the strangely many passers-by crusty 'something about mary' hair
Touching someone's butt
I especially like the obvious consequences of the BAD BEHAVIOURS, like touching someone's butt will surely cause them to fall under the oncoming train.
The water buffalo or domestic Asian water buffalo (Bubalus bubalis) is a large bovid originating in South Asia, Southeast Asia, and China. Today, it is also found in Europe, Australia, and some American countries. The wild water buffalo (Bubalus arnee) native to Southeast Asia is considered a different species, but most likely represents the ancestor of the domestic water buffalo.
Two extant types of water buffalo are recognized based on morphological and behavioural criteria – the river buffalo of South Asia and further west to the Balkans, Egypt, and Italy, and the swamp buffalo, found from Assam in the west through Southeast Asia to the Yangtze valley of China in the east. The origins of the domestic water buffalo types are debated, although results of a phylogenetic study indicate that the swamp type may have originated in China and was domesticated about 4,000 years ago, while the river type may have originated from India and was domesticated about 5,000 years ago. Water buffalo were traded from the Indus Valley Civilisation to Mesopotamia, in modern Iraq, 2500 BC by the Meluhhas. The seal of a scribe employed by an Akkadian king shows the sacrifice of water buffalo.
At least 130 million domestic water buffalo exist, and more human beings depend on them than on any other domestic animal. They are especially suitable for tilling rice fields, and their milk is richer in fat and protein than that of dairy cattle. The large feral population of northern Australia became established in the late 19th century, and smaller feral herds are in New Guinea, Tunisia, and northeastern Argentina. Feral herds are also present in New Britain, New Ireland, Irian Jaya, Papua New Guinea, Colombia, Guyana, Suriname, Brazil, and Uruguay.
CHARACTERISTICS
The skin of river buffalo is black, but some specimens may have dark, slate-coloured skin. Swamp buffalo have a grey skin at birth, but become slate blue later. Albinoids are present in some populations. River buffalo have comparatively longer faces, smaller girths, and bigger limbs than swamp buffalo. Their dorsal ridges extend further back and taper off more gradually. Their horns grow downward and backward, then curve upward in a spiral. Swamp buffalo are heavy-bodied and stockily built; the body is short and the belly large. The forehead is flat, the eyes prominent, the face short, and the muzzle wide. The neck is comparatively long, and the withers and croup are prominent. A dorsal ridge extends backward and ends abruptly just before the end of the chest. Their horns grow outward, and curve in a semicircle, but always remain more or less on the plane of the forehead. The tail is short, reaching only to the hocks. Height at withers is 129–133 cm for males, and 120–127 cm for females. They range in weight from 300–550 kg, but weights of over 1,000 kg have also been observed.
Tedong bonga is a black pied buffalo featuring a unique black and white colouration that is favoured by the Toraja of Sulawesi.
The swamp buffalo has 48 chromosomes; the river buffalo has 50 chromosomes. The two types do not readily interbreed, but fertile offspring can occur. Buffalo-cattle hybrids have not been observed to occur, and the embryos of such hybrids do not reach maturity in laboratory experiments.
The rumen of the water buffalo has important differences from that of other ruminants. It contains a larger population of bacteria, particularly the cellulolytic bacteria, lower protozoa, and higher fungi zoospores. In addition, higher rumen ammonia nitrogen (NH4-N) and higher pH have been found as compared to those in cattle
ECOLOGY AND BEHAVIOR
River buffalo prefer deep water. Swamp buffalo prefer to wallow in mudholes which they make with their horns. During wallowing, they acquire a thick coating of mud. Both are well adapted to a hot and humid climate with temperatures ranging from 0 °C in the winter to 30 °C and greater in the summer. Water availability is important in hot climates, since they need wallows, rivers, or splashing water to assist in thermoregulation. Some breeds are adapted to saline seaside shores and saline sandy terrain.
DIET
Water buffalo thrive on many aquatic plants and during floods, will graze submerged, raising their heads above the water and carrying quantities of edible plants. They eat reeds (quassab), a giant reed (birdi), a kind of bulrush (kaulan), water hyacinth, and marsh grasses. Some of these plants are of great value to local peoples. Others, such as water hyacinth, are a major problem in some tropical valleys, and water buffalo may help to keep waterways clear.
Green fodders are used widely for intensive milk production and for fattening. Many fodder crops are conserved as hay, chaffed, or pulped. Fodders include alfalfa, berseem and bancheri, the leaves, stems or trimmings of banana, cassava, fodder beet, halfa, ipil-ipil and kenaf, maize, oats, pandarus, peanut, sorghum, soybean, sugarcane, bagasse, and turnips. Citrus pulp and pineapple wastes have been fed safely to buffalo. In Egypt, whole sun-dried dates are fed to milk-buffalo up to 25% of the standard feed mixture.
REPRODUCTION
Swamp buffalo generally become reproductive at an older age than river breeds. Young males in Egypt, India, and Pakistan are first mated at about 3.0–3.5 years of age, but in Italy
they may be used as early as 2 years of age. Successful mating behaviour may continue until the animal is 12 years or even older. A good river male can impregnate 100 females in a year. A strong seasonal influence on mating occurs. Heat stress reduces libido
Although buffalo are polyoestrous, their reproductive efficiency shows wide variation throughout the year. Buffalo cows exhibit a distinct seasonal change in displaying oestrus, conception rate, and calving rate. The age at first oestrus of heifers varies between breeds from 13–33 months, but mating at the first oestrus is often infertile and usually deferred until they are 3 years old. Gestation lasts from 281–334 days, but most reports give a range between 300 and 320 days. Swamp buffalo carry their calves for one or two weeks longer than river buffalo. It is not rare to find buffalo that continue to work well at the age of 30, and instances of a working life of 40 years are recorded.
TAXONOMIC HISTORY
Carl Linnaeus first described the genus Bos and the water buffalo under the binomial Bubalis bubalus in 1758; the latter was known to occur in Asia and as a domestic form in Italy. Ellerman and Morrison-Scott treated the wild and domestic forms of the water buffalo as conspecifics whereas others treated them as different species. The nomenclatorial treatment of wild and domestic forms has been inconsistent and varies between authors and even within the works of single authors.
In March 2003, the International Commission on Zoological Nomenclature achieved consistency in the naming of wild and domestic water buffalo by ruling that the scientific name Bubalus arnee is valid for the wild form. B. bubalis continues to be valid for the domestic form and applies also to feral populations.
DOMESTICATION AND BREEDING
Water buffalo were domesticated in India about 5000 years ago, and in China about 4000 years ago. Two types are recognized, based on morphological and behavioural criteria – the river buffalo of the Indian subcontinent and further west to the Balkans and Italy, and the swamp buffalo, found from Assam in the west through Southeast Asia to the Yangtze valley of China in the east. The present-day river buffalo is the result of complex domestication processes involving more than one maternal lineage and a significant maternal gene flow from wild populations after the initial domestication events. Twenty-two breeds of the river type water buffalo are known, including Murrah, Nili-Ravi, Surti, Jafarabadi, Anatolian, Mediterranean, and Egyptian buffalo. China has a huge variety of buffalo genetic resources, comprising 16 local swamp buffalo breeds in various regions.
Results of mitochondrial DNA analyses indicate that the two types were domesticated independently. Sequencing of cytochrome b genes of Bubalus species implies that the domestic buffalo originated from at least two populations, and that the river and the swamp types have differentiated at the full species level. The genetic distance between the two types is so large that a divergence time of about 1.7 million years has been suggested. The swamp type was noticed to have the closest relationship with the tamaraw.
DISTRIBUTION OF POPULATIONS
The water buffalo population in the world is about 172 million.
IN ASIA
More than 95.8% of the world population of water buffalo are found in Asia including both river and swamp types. The water buffalo population in India numbered over 97.9 million head in 2003, representing 56.5% of the world population. They are primarily of the river type, with 10 well-defined breeds comprising Badhawari, Murrah, Nili-Ravi, Jafarabadi, Marathwada, Mehsana, Nagpuri, Pandharpuri, Toda, and Surti. Swamp buffalo occur only in small areas in the north-eastern part of the country and are not distinguished into breeds.
In 2003, the second-largest population lived in China, with 22.759 million head, all of the swamp type with breeds kept only in the lowlands, and other breeds kept only in the mountains; as of 2003, 3.2 million swamp-type carabao buffalo were in the Philippines, nearly three million swamp buffalo were in Vietnam, and 772,764 buffalo were in Bangladesh. About 750,000 head were estimated in Sri Lanka in 1997.
The water buffalo is the main dairy animal in Pakistan, with 23.47 million head in 2010. Of these, 76% are kept in the Punjab. The rest of them are mostly in the province of Sindh. Breeds used are Nili-Ravi, Kundi, and Azi Kheli. Karachi has the largest population of water buffalos for an area where fodder is not grown, consisting of 350,000 head kept mainly for milking.
In Thailand, the number of water buffalo dropped from more than 3 million head in 1996 to less than 1.24 million head in 2011. Slightly over 75% of them are kept in the country's northeastern region. The statistics also indicate that by the beginning of 2012, less than one million were in the country, partly as a result of illegal shipments to neighboring countries where sales prices are higher than in Thailand.
Water buffalo are also present in the southern region of Iraq, in the marshes. These marshes were drained by Saddam Hussein in 1991 in an attempt to punish the south for the uprisings of 1991. Following 2003, and the fall of the Saddam regime, these lands were reflooded and a 2007 report in the provinces of Maysan and Thi Qar shows a steady increase in the number of water buffalo. The report puts the number at 40,008 head in those two provinces.
IN EUROPE AND THE MEDITERRANEAN
Water buffalo likely were introduced to Europe from India or other Oriental countries. To Italy they were introduced about the year 600 in the reign of the Longobard King Agilulf. As they appear in the company of wild horses, they probably were a present from the Khan of the Avars, a Turkic nomadic tribe that dwelt near the Danube River at the time. Sir H. Johnston knew of a herd of water buffalo presented by a King of Naples to the Bey of Tunis in the mid-19th century that had resumed the feral state in northern Tunis.
European buffalo are all of the river type and considered to be of the same breed named Mediterranean buffalo. In Italy, the Mediterranean type was particularly selected and is called Mediterranean Italian breed to distinguish it from other European breeds, which differ genetically. Mediterranean buffalo are also found in Romania, Bulgaria, Greece, Albania, Kosovo, and the Republic of Macedonia, with a few hundred in the United Kingdom, Germany, the Netherlands, Switzerland, and Hungary. Little exchange of breeding buffalo has occurred among countries, so each population has its own phenotypic features and performances. In Bulgaria, they were crossbred with the Indian Murrah breed, and in Romania, some were crossbred with Bulgarian Murrah. Populations in Turkey are of the Anatolian buffalo breed.
IN AUSTRALIA
Between 1824 and 1849, water buffalo were introduced into the Northern Territory from Timor, Kisar, and probably other islands in the Indonesian archipelago. In 1886, a few milking types were brought from India to Darwin. They have been the main grazing animals on the subcoastal plains and river basins between Darwin and Arnhem Land since the 1880s. In the early 1960s, an estimated population of 150,000 to 200,000 buffalo were living in the plains and nearby areas.
They became feral and are causing significant environmental damage. Buffalo are also found in the Top End. As a result, they were hunted in the Top End from 1885 until 1980. The commencement of the brucellosis and tuberculosis campaign (BTEC) resulted in a huge culling program to reduce buffalo herds to a fraction of the numbers that were reached in the 1980s. The BTEC was finished when the Northern Territory was declared free of the disease in 1997. Numbers dropped dramatically as a result of the campaign, but have since recovered to an estimated 150,000 animals across northern Australia in 2008.
During the 1950s, buffalo were hunted for their skins and meat, which was exported and used in the local trade. In the late 1970s, live exports were made to Cuba and continued later into other countries. Buffalo are now crossed with riverine buffalo in artificial insemination programs, and may be found in many areas of Australia. Some of these crossbreds are used for milk production. Melville Island is a popular hunting location, where a steady population up to 4,000 individuals exists. Safari outfits are run from Darwin to Melville Island and other locations in the Top End, often with the use of bush pilots. The horns, which can measure up to a record of 3.1 m tip-to-tip, are prized hunting trophies.
The buffalo have developed a different appearance from the Indonesian buffalo from which they descend. They live mainly in freshwater marshes and billabongs, and their territory range can be quite expansive during the wet season. Their only natural predators in Australia are adult saltwater crocodiles, with whom they share the billabongs, and dingoes, which have been known to prey on buffalo calves and occasionally adult buffalo when the dingoes are in large packs.
Buffalo were exported live to Indonesia until 2011, at a rate of about 3000 per year. After the live export ban that year, the exports dropped to zero, and had not resumed as of June 2013.
IN SOUTH AMERICA
Water buffalo were introduced into the Amazon River basin in 1895. They are now extensively used there for meat and dairy production. In 2005, the buffalo herd in the Brazilian Amazon stood at roughly 1.6 million head, of which 460,000 were located in the lower Amazon floodplain. Breeds used include Mediterranean from Italy, Murrah and Jafarabadi from India, and Carabao from the Philippines.
During the 1970s, small herds were imported to Costa Rica, Ecuador, Cayenne, Panama, Surinam, Guyana, and Venezuela.
In Argentina, many game ranches raise water buffalo for commercial hunting
IN NORTH AMERICA
In 1974, four water buffalo were imported to the United States from Guam to be studied at the University of Florida. In February 1978, the first herd arrived for commercial farming. Until 2002, only one commercial breeder was in the United States. Water buffalo meat is imported from Australia. Until 2011, water buffalo were raised in Gainesville, Florida, from young obtained from zoo overflow. They were used primarily for meat production, frequently sold as hamburger.[38] Other US ranchers use them for production of high-quality mozzarella cheese.
HUSBANDRY
The husbandry system of water buffalo depends on the purpose for which they are bred and maintained. Most of them are kept by people who work on small farms in family units. Their buffalo live in very close association with them, and are often their greatest capital asset. The women and girls in India generally look after the milking buffalo while the men and boys are concerned with the working animals. Throughout Asia, they are commonly tended by children who are often seen leading or riding their charges to wallowing places. Water buffalo are the ideal animals for work in the deep mud of paddy fields because of their large hooves and flexible foot joints. They are often referred to as "the living tractor of the East". It probably is possible to plough deeper with buffalo than with either oxen or horses. They are the most efficient and economical means of cultivation of small fields. In most rice-producing countries, they are used for threshing and for transporting the sheaves during the rice harvest. They provide power for oilseed mills, sugarcane presses, and devices for raising water. They are widely used as pack animals, and in India and Pakistan also for heavy haulage. In their invasions of Europe, the Turks used buffalo for hauling heavy battering rams. Their dung is used as a fertilizer, and as a fuel when dried.
Buffalo contribute 72 million tones of milk and three million tones of meat annually to world food, much of it in areas that are prone to nutritional imbalances. In India, river-type buffalo are kept mainly for milk production and for transport, whereas swamp-type buffalo are kept mainly for work and a small amount of milk.
DAIRY PRODUCTS
Water buffalo milk presents physicochemical features different from that of other ruminant species, such as a higher content of fatty acids and proteins. The physical and chemical parameters of swamp and river type water buffalo milk differ. Water buffalo milk contains higher levels of total solids, crude protein, fat, calcium, and phosphorus, and slightly higher content of lactose compared with those of cow milk. The high level of total solids makes water buffalo milk ideal for processing into value-added dairy products such as cheese. The conjugated linoleic acid (CLA) content in milk ranged from 4.4 mg/g fat in September to 7.6 mg/g fat in June. Seasons and genetics may play a role in variation of CLA level and changes in gross composition of the water buffalo milk.
Water buffalo milk is processed into a large variety of dairy products:
- Cream churns much faster at higher fat levels and gives higher overrun than cow cream.
- Butter from water buffalo cream displays more stability than that from cow cream.
- Ghee from water buffalo milk has a different texture with a bigger grain size than ghee from cow milk.
- Heat-concentrated milk products in the Indian subcontinent include paneer, khoa, rabri, kheer and basundi.
- Fermented milk products include dahi, yogurt, and chakka.
- Whey is used for making ricotta and mascarpone in Italy, and alkarish in Syria and Egypt.
- Soft cheeses made include mozzarella in Italy, karish, mish, and domiati in Egypt, madhfor in Iraq, alghab in Syria, kesong puti in the Philippines, and vladeasa in Romania.
- The semihard cheese beyaz peynir is made in Turkey.
- Hard cheeses include braila in Romania, rahss in Egypt, white brine in Bulgaria, and akkawi in Syria.
- Watered-down buffalo milk is used as a cheaper alternative to regular milk.
MEAT AND SKIN PRODUCTS
Water buffalo meat, sometimes called "carabeef", is often passed off as beef in certain regions, and is also a major source of export revenue for India. In many Asian regions, buffalo meat is less preferred due to its toughness; however, recipes have evolved (rendang, for example) where the slow cooking process and spices not only make the meat palatable, but also preserve it, an important factor in hot climates where refrigeration is not always available.Their hides provide tough and useful leather, often used for shoes.
BONE AND HORN PRODUCTS
The bones and horns are often made into jewellery, especially earrings. Horns are used for the embouchure of musical instruments, such as ney and kaval.
ENVIRONMENTAL EFFECTS
Wildlife conservation scientists have started to recommend and use introduced populations of feral domestic water buffalo in far-away lands to manage uncontrolled vegetation growth in and around natural wetlands. Introduced water buffalo at home in such environs provide cheap service by regularly grazing the uncontrolled vegetation and opening up clogged water bodies for waterfowl, wetland birds, and other wildlife. Grazing water buffalo are sometimes used in Great Britain for conservation grazing, such as in Chippenham Fen National Nature Reserve. The buffalo can better adapt to wet conditions and poor-quality vegetation than cattle.
Currently, research is being conducted at the Lyle Center for Regenerative Studies to determine the levels of nutrients removed and returned to wetlands when water buffalo are used for wetland vegetation management.
However, in uncontrolled circumstances, water buffalo can cause environmental damage, such as trampling vegetation, disturbing bird and reptile nesting sites, and spreading exotic weeds.
RESEARCH
The world's first cloned buffalo was developed by Indian scientists from National Dairy Research Institute, Karnal. The buffalo calf was named Samrupa. The calf did not survive more than a week, and died due to some genetic disorders. So, the scientists created another cloned buffalo a few months later, and named it Garima.
On 15 September 2007, the Philippines announced its development of Southeast Asia's first cloned buffalo. The Philippine Council for Agriculture, Forestry and Natural Resources Research and Development (PCARRD), under the Department of Science and Technology in Los Baños, Laguna, approved this project. The Department of Agriculture's Philippine Carabao Center (PCC) will implement cloning through somatic cell nuclear transfer as a tool for genetic improvement in water buffalo. "Super buffalo calves" will be produced. There will be no modification or alteration of the genetic materials, as in genetically modified organisms.
On 1 January 2008, the Philippine Carabao Center in Nueva Ecija, per Filipino scientists, initiated a study to breed a super water buffalo that could produce 4 to 18 litres of milk per day using gene-based technology. Also, the first in vitro river buffalo was born there in 2004 from an in vitro-produced, vitrified embryo, named "Glory" after President Gloria Macapagal-Arroyo. Joseph Estrada's most successful project as an opposition senator, the PCC was created through Republic Act 3707, the Carabao Act of 1992.
IN CULTURE
Some ethnic groups, such as Batak and Toraja in Indonesia and the Derung in China, use water buffalo or kerbau (called horbo in Batak or tedong in Toraja) as sacrificial animals at several festivals.
- Legend has it that the Chinese philosophical sage Laozi left China through the Han Gu Pass riding a water buffalo.
- According to Hindu lore, the god of death Yama, rides on a male water buffalo.
- The carabao subspecies is considered a national symbol in the Philippines.
- In Vietnam, water buffalo are often the most valuable possession of poor farmers: "Con trâu là đầu cơ nghiệp". They are treated as a member of the family: "Chồng cày, vợ cấy, con trâu đi bừa" ("The husband ploughs, the wife sows, water buffalo draws the rake") and are friends of the children. Children talk to their water buffalo, "Bao giờ cây lúa còn bông. Thì còn ngọn cỏ ngoài đồng trâu ăn." (Vietnamese children are responsible for grazing water buffalo. They feed them grass if they work laboriously for men.) In the old days, West Lake, Hà Nội, was named Kim Ngưu - Golden Water Buffalo.
- The Yoruban Orisha Oya (goddess of change) takes the form of a water buffalo.
FIGHTING FESTIVALS
- Pasungay Festival is held annually in the town of San Joaquin, Iloilo in the Philippines.
- Moh juj Water Buffalo fighting, is held every year in Bhogali Bihu in Assam. Ahotguri in Nagaon is famous for it.
- Do Son Water Buffalo Fighting Festival of Vietnam, held each year on the ninth day of the eighth month of the lunar calendar at Do Son Township, Haiphong City in Vietnam, is one of the most popular Vietnam festivals and events in Haiphong City. The preparations for this buffalo fighting festival begin from the two to three months earlier. The competing buffalo are selected and methodically trained months in advance. It is a traditional festival of Vietnam attached to a Water God worshipping ceremony and the Hien Sinh custom to show martial spirit of the local people of Do Son, Haiphong.
- "Hai Luu" Water Buffalo Fighting Festival of Vietnam, According to ancient records, the buffalo fighting in Hai Luu Commune has existed from the 2nd century B.C. General Lu Gia at that time, had the buffalo slaughtered to give a feast to the local people and the warriors, and organized buffalo fighting for amusement. Eventually, all the fighting buffalo will be slaughtered as tributes to the deities.
- "Ko Samui" Water Buffalo Fighting Festival of Thailand, is a very popular event held on special occasions such as New Year's Day in January, and Songkran in mid-April, this festival features head-wrestling bouts in which two male Asian water buffalo are pitted against one another. Unlike in Spanish Bullfighting, wherein bulls get killed while fighting sword-wielding men, Buffalo Fighting Festival held at Ko Samui, Thailand is fairly harmless contest. The fighting season varies according to ancient customs & ceremonies. The first Buffalo to turn and run away is considered the loser, the winning buffalo becomes worth several million baht. Ko Samui is an island in the Gulf of Thailand in the South China Sea, it is 700 km from Bangkok and is connected to it by regular flights.
- "Ma'Pasilaga Tedong" Water Buffalo Fighting Festival, in Tana Toraja Regency of Sulawesi Island, Indonesia, is a very popular event where the Rambu Solo' or a Burial Festival took place in Tana Toraja.
RACING FESTIVALS
Carabao Carroza Festival is being held annually every May in the town of Pavia, Iloilo, Philippines.
Kambala races of Karnataka, India, take place between December and March. The races are conducted by having the water buffalo (he buffalo) run in long parallel slushy ditches, where they are driven by men standing on wooden planks drawn by the buffalo. The objectives of the race are to finish first and to raise the water to the greatest height and also a rural sport. Kambala races are arranged with competition, as well as without competition and as a part of thanks giving (to god) in about 50 villages of coastal Karnataka.
In the Chonburi Province of Thailand, and in Pakistan, there are annual water buffalo races.
Chon Buri Water buffalo racing festival, Thailand In downtown Chonburi, 70 km south of Bangkok, at the annual water buffalo festival held in mid-October. About 300 buffalo race in groups of five or six, spurred on by bareback jockeys wielding wooden sticks, as hundreds of spectators cheer. The water buffalo has always played an important role in agriculture in Thailand. For farmers of Chon Buri Province, near Bangkok, it is an important annual festival, beginning in mid-October. It is also a celebration among rice farmers before the rice harvest. At dawn, farmers walk their buffalo through surrounding rice fields, splashing them with water to keep them cool before leading them to the race field. This amazing festival started over a hundred years ago when two men arguing about whose buffalo was the fastest ended up having a race between them. That’s how it became a tradition and gradually a social event for farmers who gathered from around the country in Chonburi to trade their goods. The festival also helps a great deal in preserving the number of buffalo, which have been dwindling at quite an alarming rate in other regions. Modern machinery is rapidly replacing buffalo in Thai agriculture. With most of the farm work mechanized, the buffalo-racing tradition has continued. Racing buffalo are now raised just to race; they do not work at all. The few farm buffalo which still do work are much bigger than the racers because of the strenuous work they perform. Farm buffalo are in the "Buffalo Beauty Pageant", a Miss Farmer beauty contest and a comic buffalo costume contest etc.. This festival perfectly exemplifies a favored Thai attitude to life — "sanuk," meaning fun.
Babulang Water buffalo racing festival, Sarawak, Malaysia, is the largest or grandest of the many rituals, ceremonies and festivals of the traditional Bisaya (Borneo) community of Limbang, Sarawak. Highlights are the Ratu Babulang competition and the Water buffalo races which can only be found in this town in Sarawak, Malaysia.
Vihear Suor village Water buffalo racing festival, in Cambodia, each year, people visit Buddhist temples across the country to honor their deceased loved ones during a 15-day period commonly known as the Festival of the Dead but in Vihear Suor village, about 35 km northeast of Cambodia, citizens each year wrap up the festival with a water buffalo race to entertain visitors and honour a pledge made hundreds of years ago. There was a time when many village cattle which provide rural Cambodians with muscle power to plough their fields and transport agricultural products died from an unknown disease. The villagers prayed to a spirit to help save their animals from the disease and promised to show their gratitude by holding a buffalo race each year on the last day of "P'chum Ben" festival as it is known in Cambodian. The race draws hundreds of spectators who come to see riders and their animals charge down the racing field, the racers bouncing up and down on the backs of their buffalo, whose horns were draped with colorful cloth.
Pothu puttu matsaram, Kerala, South India, is similar to Kambala races.

Status: A scarce winter visitor throughout Ireland and rare breeding species, mainly in the south and east. Favours uplands and coastal lowlands.
Conservation Concern: Amber-listed in Ireland due to its small breeding population. The European population is currently evaluated as Depleted due to a large historical decline.
Identification: The only Irish owl species likely to be seen hunting during the day. Very similar in appearance to Long-eared Owl in all plumages. Adult Short-eared Owls can be identified by their yellow eyes and very small "ear" tufts. The black steeaking on the body tends to be much coarser than on Long-eared Owl. Juvenile Short-eareds are identical to juvenile Long-eared Owls, but have yellow eyes.
Similar Species: Long-eared Owl, Barn Owl.
Call: Generally silent when seen in Ireland. Display includes a quiet series of hoots given in flight.
Diet: As for Long-eared Owl. Comprises small mammals, frogs and birds.
Breeding: Rare and sporadic breeding species in uplands throughout Ireland. The majority of the European population breeds in Scandinavia and Russia.
Wintering: Widespread winter visitor to coastal lowlands (dunes, scrubby fields, machair). Sometimes two or more Short-eared Owls can be seen hunting together at favoured sites.
Where to See: The Wicklow coast, including the East Coast Nature Reserve is a good area to look for Short-eared Owls in winter. Numbers fluctuate from year to year, so may absent from even optimal sites in some years.

Physical characteristics
Short-eared Owls are medium-sized owls with mottled brown and buff plumage. Their facial disks are light, with dark patches at the eyes. They have short ear-tufts that are usually held down, out of view. They are light underneath, with finely streaked chests and bellies. Males are paler than females. Short-eared Owls have dark markings at the wrist on both the underside and upper side of the wings. In flight they can be hard to tell from the closely related Long-eared Owls, except by behavior and habitat.
Because they are active during the day, Short-eared Owls are easier to see than most other owls. They are especially active at dawn and dusk, and they perform dramatic courtship flights, complete with vocalizing and wing clapping, during the breeding season. They are chase-predators and hunt by flying low over an open area, with their wings at a slight dihedral, somewhat like Northern Harriers. Their buoyant wing-beats give them a distinctive moth-like appearance.
Habitat
Short-eared Owls inhabit open terrain in all seasons. They use shrub-steppe, grasslands, agricultural areas, marshes, wet meadows, and shorelines. They are often seen perched on fence posts or pieces of driftwood.
Other details
Asio flammeus is a widespread but patchily distributed breeder across much of Europe, which accounts for less than a quarter of its global breeding range. Its European breeding population is relatively large (>58,000 pairs), but underwent a large decline between 1970-1990. Although declines continued in a few countries during 1990-2000, they abated across most of Europe, and the species was broadly stable overall. Nevertheless, its total population size remains below the level that preceded its decline.
This owl inhabits a large part of Eurasia, North America and southern South America. In Europe, especially in the south, its distribution is increasingly fragmented. The total population of the European Union is estimated at 1500-3500 breeding pairs. It fluctuates according to rodent densities, but seems to decrease following mainly habitat loss, but also persecution and use of pesticides (especially rodenticides). Many birds are also killed along roads and railways.
Fluctuations in the Short-eared Owl population, due most likely to cyclical variation in the population of voles, make it difficult to determine long-term trends. However, declines have been recorded from many parts of the owls range, and Short-eared Owls are listed as an at-risk species by Partners in Flight. Development and agriculture, which result in loss of habitat, are the most significant threats to the population.
Feeding
Short-eared Owls eat small mammals, especially voles. They take other small rodents, shrews, rabbits, gophers, bats, and muskrats as well. Occasionally, they prey on birds.
Conservation
This species has an extremely large range, and hence does not approach the thresholds for Vulnerable under the range size criterion (Extent of Occurrence 30% decline over ten years or three generations). The population size is extremely large, and hence does not approach the thresholds for Vulnerable under the population size criterion (10% in ten years or three generations, or with a specified population structure). For these reasons the species is evaluated as Least Concern. [conservation status from birdlife.org]
Breeding
Courtship and territorial behaviour is spectacular for an Owl. Males perform aerial displays by rising quickly with rhythmic and exaggerated wing beats, hovering, gliding down, and rising again, often 200 to 400 meters above ground. Wing claps, in bursts of 2 to 6 per second, are often made during this flight and some singing occurs. The flight can be ended with a spectacular descent where the male hold his wings aloft and shimmies rapidly to the ground. Two birds may engage in flight, locking talons, and fighting briefly. Often, a display where one bird flashes its light underwing towards another is used during territorial and courtship flights.
The Short-eared Owl nests on the ground, unlike most other Owls. Nests are usually situated in the shelter of a grass mound, under a grass tuft, or among herbaceous ground cover. Nests are loosely constructed by the female, who scrapes a spot on the ground and then lines the scrape with grass stems, herb stalks, and feathers plucked from her breast. Clutch sizes range from 4 to 14 eggs (average 5 to 7), with large clutches laid during years of high food abundance. Clutch size increases from south to north. Eggs are laid every 1 to 2 days and incubation commences with the first. Incubation is done largely by the female, with the male bringing food to the nest and occasionally taking a turn incubating. Young grow very rapidly after hatching, and begin to wander from the nest as soon as 12 days, an adaptation for a ground-nesting species to reduce the amount of time they are vulnerable to predation. Young fledge at about 4 weeks.
The Short-eared Owl routinely lays replacement clutches, because of high predation rates. In southern areas, it may raise 2 broods in 1 year. Because reproductive success is relatively poor, the ability to lay large clutches helps populations recover after periodic declines.
The Short-eared Owl is highly migratory, and nomadic, except in southern parts of its range. Movements of up to 2,000 kilometers have been documented. This Owl has relatively small nesting territories and home ranges, varying from 15 to 200 hectares (35 to 500 acres), and may nest in loose colonies in excellent habitat. Because of its nomadic tendencies, mate and site fidelity are very low. Breeders tend to wander until they find areas with high densities of prey before settling to breed. In winter, large numbers of Owls will occur in areas with lots of food. Communal winter roosts of up to 200 birds are known, with these birds ranging over nearby areas to hunt. Resident Owls will defend winter foraging territories of about 6 hectares (15 acres), before expanding the territory size during the breeding season.
Migration
Thought to be highly migratory in N part of range, though migration perhaps confused with nomadic food searches and juvenile dispersal; also, wintering areas may become breeding areas if food plentiful. Although present throughout year in middle latitudes, ringing data indicate seasonal N-S and W-SW migration: bird rings in Oklahoma recovered 1730 km SSE in California. In Europe and Asia, migratory in N of range: N populations winter from British Is, S Scandinavia and C Asia S to N half of Africa and parts of S & E Asia; known to breed in N China and winter in S China. Accidental Spitsbergen, Bear Is, Jan Mayen, Azores, Madeira and Cape Verde Is.

Psychology is an academic and applied discipline that involves the scientific study of mental functions and behaviours. Psychology has the immediate goal of understanding individuals and groups by both establishing general principles and researching specific cases, and by many accounts it ultimately aims to benefit society. In this field, a professional practitioner or researcher is called a psychologist and can be classified as a social, behavioural, or cognitive scientist. Psychologists attempt to understand the role of mental functions in individual and social behaviour, while also exploring the physiological and neurobiological processes that underlie certain cognitive functions and behaviours.
Psychologists explore concepts such as perception, cognition, attention, emotion, phenomenology, motivation, brain functioning, personality, behaviour, and interpersonal relationships. Psychologists of diverse stripes also consider the unconscious mind. Psychologists employ empirical methods to infer causal and correlational relationships between psychosocial variables. In addition, or in opposition, to employing empirical and deductive methods, some—especially clinical and counseling psychologists—at times rely upon symbolic interpretation and other inductive techniques. Psychology has been described as a "hub science",[8] with psychological findings linking to research and perspectives from the social sciences, natural sciences, medicine, and the humanities, such as philosophy.
While psychological knowledge is often applied to the assessment and treatment of mental health problems, it is also directed towards understanding and solving problems in many different spheres of human activity. The majority of psychologists are involved in some kind of therapeutic role, practicing in clinical, counseling, or school settings. Many do scientific research on a wide range of topics related to mental processes and behaviour, and typically work in university psychology departments or teach in other academic settings (e.g., medical schools, hospitals). Some are employed in industrial and organizational settings, or in other areas such as human development and ageing, sports, health, and the media, as well as in forensic investigation and other aspects of law.
It still fascinates me, how different life forms, of many sizes and scales can create a micro-ecosystem directly relevant to the surface, temperatures, exposures etc. etc. etc.
I was up at one of our local churchyards for my walk this morning when I noticed this female Mallard.
She was quacking away and then flew up into a hole in a tree, if she's nesting there I worry about the babies when they hatch.
The pond is just across a fairly busy road if they try to get there.
These pics were part of a series taken at a distance from the shore at Burghead. We were watching juvenile gannets diving for fish when we saw this one touch down in the sea and attack a long tailed duck. It spent several minutes wrestling with its victim apparently trying to drown it. A second gannet swooped in taking the attacker by surprise. The duck was dropped but it was impossible to tell whether it escaped as it was never seen again.
Governments around the world are drawing on behavioural insights to improve public policy outcomes: from automatic enrolment for pensions, to better tax compliance, to increasing the supply of organ donation.
But those very same policy makers are also subject to biases that can distort decision making. The Behavioural Insights Team has been studying those biases and what can be done to counter them, in collaboration with Jill Rutter and Julian McCrae of the Institute for Government.
The report was launched with remarks from Alex Chisholm, Permanent Secretary at the Department for Business, Energy, and Industrial Strategy.
Dr Michael Hallsworth, Director of the Behavioural Insights Team in North America presented the key findings.
The findings, their relevance to policy making today, and what they mean for the way governments make decisions were discussed by:
Polly Mackenzie, Director of Policy for the Deputy Prime Minister, 2010–15 and now Director of Demos
Dr Tony Curzon Price, Economic Advisor to the Secretary of State for Business, Energy and Industrial Strategy.
The event was chaired by Jill Rutter, Programme Director at the Institute for Government.

NOT SURE WHAT Bear-walker means in Ojibwa Indian folklore but in my survival training courses, it was noted as uncontrolled fear or anxiety, either individually, or collectively as a group, with the end result being impulsive and dangerous behaviour that would impede or extinguish your chance of survival in the great outdoors.
It's a seasoned hunter lost in the wild for only a few days whose mind has snapped and who runs away from, and not to, a Canadian Forces search and rescue helicopter. It's a firefighter who gets lost in the wild, and keeps pushing forward, going, going…trying to catch up to friends, until exhausted, at which point both thirsty and hungry, he slips. Down a small hill. And his leg, is now broken. So, now what?
And when you're in the wild… you are not at home. Which should be obvious enough, but it often isn't.
You are far from having the usual community supports.
And that's when the Bear-walker can descend on you suddenly.
And if you lose the battle with the Bear-walker… you can easily forfeit your life.
I was taking a few shots of a Great Blue Heron that was in the clearing, near-by. It took off from a rock and I followed its flight when suddenly my camera strap caught my canoe paddle handle, wrenched the camera from my hand with great force, and out of my hands it went.
I last saw my Canon DSLR fly straight away, and then immediately down into the mirky waters.
Blewb!
My Canon SLR that had cost me $2600, my pro lenses that cost $1300, my memory card etc., now gone!
Enter the Bear-walker.
The Bear-walker is telling me to jump in. Go after your equipment. Quick!!!!!!!!!!
NOW!!
Cool head prevails.
The water is mirky. Can't see a thing. Could jump in and get skewered. What about lake reeds? Could get tangled up and hopelessly trapped. Not likely any undertow. Not likely. How do I secure the canoe so that it doesn't float away? Actually I can't. If I jump in, I could capsized all the canoe's contents! And of course, there is no one else around!
Of, course.
No, no, no…jump in. Soon there won't be a trace of your camera…
(Shut-the-hell-up Bear-walker)
Did you catch that, readership?
The Bear-walker is using my $4,000 anxiety to get me to react without heeding the danger. I acknowledge he is there, and remind myself of his existence by entering into brief dialogue with him (that single shut-up I issue to quiet my mind). He is the watcher in the woods. But the harmful one. He waits for you to make a mistake. Then, he'll help you to make more, always, always under the guise of making your situation better.
Desolate areas are always the haunt of demons.
At least that's what my Catholic version of the New Testament alludes to.
All right. Take a breather.
Slow it down.
Surprisingly, a steady stream of bubbles are marking the descent of my camera.
Gee, how far down is it?
Clips of Voyage to the Bottom of the Sea fill my head, briefly.
Seaview One. Damn, I loved that show. Whatever happened to that show?
Paddle goes down into the brackish waters.
Pure stench.
And my arm and paddle are now submerged up to my armpit.
I think I'm hitting bottom.
Yes, I am!
I pull my arm out. Hey, where'd that black licorice come from?
Uh, oh… not licorice, but leeches!! Deal with those later.
I maneuver the canoe about. There is sun glare everywhere.
I take the second paddle, and block the sun over the canoe gunwale. Turns out to be a good idea.
Can see a little into the mirk, now.
HEY.
HEY!!!!!!!!!!!!
Is that my camera strap shooting straight up, with the eyelet drifting backward from an unseen current?
Damn hell, it is!!
Oh, no. Can I even reach the camera-strap eyelet?
Plus, I've also got to deal with light refraction in the water.
Where the camera strap appears to be… is NOT… where it is.
Try to snag it.
I'll use the thoughtfully placed hook on paddle's hand grip, yeah! Who thought to put a hook there?
Damn, good, idea.
Numerous snag attempts. Numerous more snag attempts. Fifteen minutes pass.
Keep light blocking paddle in place. Leaning forward, but… careful, don't TIP the canoe!
The Bear-walker wanted me to lean further out. Nope.
Almost there… almost there…
GOT IT!!
I got my camera.
Pull slowly to the surface.
Yahoo, I got my camera back! I ACTUALLY, got it back.
But… is it any good?
Remove battery. Remove memory card.
Back on shore I separate lens, and camera to dry out separately.
I return the canoe to the outfitter. I tell my tale of camera woe to a disinterested youth manning the canoe hangar.
He looks away, as I speak. Women in bikinis, frolic by. I reach back and grab one of the canoe paddles, and slam the oar down on the picnic table he is sitting at.
He is now max. attentive to every word I say.
Damn, I hate the rude.
I realize right away, I don't think he's ever met a real Canadian.
Bet, he never forgets me.
He smiles and waves as I leave. The smile is fake.
Back home, I put both lens and camera back together, and right into a ten pound bag of basmati rice! That should pull the remaining moisture out of the camera.
In five days I should know IF my camera and lense can be saved! Keep ya' posted.
And Clear may laugh at the Bear-walker. But the Bear-walker has claimed many, many lives. And he's right there in your thoughts, pushing you to keep going, to act quickly without taking inventory, to not bother to hydrate yourself etc. and a million other things ill thought out things.
The Bear-walker stalks people in restaurants. Sometimes, even in your home.
Do you know how many people have died from choking in restaurants?
Here's how it unfolds. A person in trouble, starts choking and can't clear his/her throat. They don't want to make a scene so they get up and leave the table. They'll wave off others who try to help. They make their way to the bathroom because it's embarrassing to cough up dramatically in front of denizens of other folk seated around you.
If a cougher leaves the table follow him, and alert staff. Panic is starting and the person is not thinking clearly. With each step, the person is running out of air.
In the restaurant setting, the person can maintain their composure. But in the bathroom, pure panic will set in. And now the person is alone!
It will end horribly, and quickly.
That's exactly what the Bear-walker wanted. You remove yourself from friends, and family, and specially trained restaurant staff who could very easily have saved you.
When you are running out of air… you won't be able to save yourself. Remember that.
And at home don't let the Bear-walker tell you to ignore that unusual pain in your abdomen, or chest. Don't let him trick you into thinking you can sleep it off.
Yes, be aware of, and beware, the Bear-walker!

In my opinion, our local street cleaners - working for Veolia - do a good job; collecting and bagging waste in the company's purple bags.
Which are supposed to be collected reasonably quickly.
But while the "official" bags await collection, they act like a "magnet" - tacitly encouraging a few people to add their own waste bags to the pile.
The mallard (/ˈmælɑrd/ or /ˈmælərd/) or wild duck (Anas platyrhynchos) is a dabbling duck which breeds throughout the temperate and subtropical Americas, Europe, Asia, and North Africa, and has been introduced to New Zealand, Australia, Peru, Brazil, Uruguay, Argentina, Chile, the Falkland Islands and South Africa.[2] This duck belongs to the subfamily Anatinae of the waterfowl family Anatidae.
The male birds (drakes) have a glossy green head and are grey on wings and belly, while the females have mainly brown-speckled plumage. Both genders have an area of white-bordered black speculum feathers which commonly also include irridescent blue feathers especially among males. Mallards live in wetlands, eat water plants and small animals, and are social animals preferring to congregate in groups or flocks of varying sizes. This species is the ancestor of most breeds of domestic ducks.[3]
Taxonomy and evolution
The mallard was one of the many bird species originally described by Carl Linnaeus in his 18th-century work, Systema Naturae, and still bears its original binomial name.[4]
The name mallard is derived from the Old French malart or mallart "wild drake", although its ultimate derivation is unclear. It may be related to (or at least influenced by) an Old High German masculine proper name Madelhart, clues lying in the alternate English forms "maudelard" or "mawdelard".[5] Masle (male) has also been proposed as an influence.[6] Mallards frequently interbreed with their closest relatives in the genus Anas, such as the American black duck, and also with species more distantly related, such as the northern pintail, leading to various hybrids that may be fully fertile.[7] This is quite unusual among such different species, and apparently is because the mallard evolved very rapidly and recently, during the Late Pleistocene. The distinct lineages of this radiation are usually kept separate due to non-overlapping ranges and behavioural cues, but are still not fully genetically incompatible.[8] Mallards and their domesticated conspecifics are also fully interfertile.
The genome of Anas platyrhynchos was sequenced in 2013.[9]
Mallards appear to be closer to their Indo-Pacific relatives than to their American ones judging from biogeography. Considering mitochondrial DNA D-loop sequence data, they may have evolved in the general area of Siberia; mallard bones rather abruptly appear in food remains of ancient humans and other deposits of fossil bones in Europe, without a good candidate for a local predecessor species.[10] The large ice age palaeosubspecies which made up at least the European and west Asian populations during the Pleistocene has been named Anas platyrhynchos palaeoboschas.[citation needed]
In their mitochondrial DNA, mallards are differentiated between North America and Eurasia,[11] however, in the nuclear genome there is a particular lack of genetic structure.[12] Haplotypes typical of American mallard relatives and spotbills can be found in mallards around the Bering Sea.[13] The Aleutian Islands hold a population of mallards that appear to be evolving towards a subspecies, as gene flow with other populations is very limited.[10]
The size of the mallard varies clinally, and birds from Greenland, although larger than birds further south, have smaller bills and are stockier. They are sometimes separated as subspecies, the Greenland mallard (A. p. conboschas).[citation needed]
Description
The mallard is a medium-sized waterfowl species although is often slightly heavier than most other dabbling ducks. It is 50–65 cm (20–26 in) long (of which the body makes up around two-thirds), has a wingspan of 81–98 cm (32–39 in),[14] and weighs 0.72–1.58 kg (1.6–3.5 lb).[15][16] Among standard measurements, the wing chord is 25.7 to 30.6 cm (10.1 to 12.0 in), the bill is 4.4 to 6.1 cm (1.7 to 2.4 in) and the tarsus is 4.1 to 4.8 cm (1.6 to 1.9 in).[17]
The breeding male mallard is unmistakable, with a glossy bottle-green head and white collar which demarcates the head from the purple-tinged brown breast, grey brown wings, and a pale grey belly. The rear of the male is black, with the dark tail having white borders.[18] The bill of the male is a yellowish orange tipped with black while that of the female is generally darker ranging from black to mottled orange. The female mallard is predominantly mottled with each individual feather showing sharp contrast from buff to very dark brown, a coloration shared by most female dabbling ducks, and has buff cheeks, eyebrow, throat and neck with a darker crown and eye-stripe.[18]
Owing to their highly 'malleable' genetic code, Mallards can display a large amount of variation, as seen here with this female, who displays faded or 'apricot' plumage.
Both male and female mallards have distinct iridescent purple blue speculum feathers edged with white, prominent in flight or at rest, though temporarily shed during the annual summer moult. Upon hatching, the plumage colouring of the duckling is yellow on the underside and face (with streaks by the eyes) and black on the backside (with some yellow spots) all the way to the top and back of the head. Its legs and bill are also black. As it nears a month in age, the duckling's plumage will start becoming drab, looking more like the female (though its plumage is more streaked) and its legs will lose their dark grey colouring.[18] Two months after hatching, the fledgling period has ended and the duckling is now a juvenile. Between three to four months of age, the juvenile can finally begin flying as its wings are fully developed for flight (which can be confirmed by the sight of purple speculum feathers). Its bill will soon lose its dark grey colouring and its sex can finally be distinguished visually by three factors. The bill colouring is yellow in males, black and orange for females. The breast feathers are reddish-brown for males, brown for females. The centre tail feather is curled for males (called a drake feather), straight for females.[citation needed]
During the final period of maturity leading up to adulthood (6–10 months of age), the plumage of female juveniles remains the same while the plumage of male juveniles slowly changes to its characteristic colours.[citation needed] This plumage change also applies to adult mallard males when they transition in and out of their non-breeding eclipse plumage at the beginning and the end of the summer moulting period. The adulthood age for mallards is 14 months and the average life expectancy is 3 years, but they can live to twenty.[19]
Several species of duck have brown-plumaged females which can be confused with the female mallard. The female gadwall (A. strepera) has an orange-lined bill, white belly, black and white speculum which is seen as a white square on the wings in flight, and is a smaller bird.[18] More similar to the female mallard in North America are the American black duck (A. rubripes), which is notably darker hued in both sexes than the mallard, and the mottled duck (A. fulvigula), which is somewhat darker than the female mallard, with no white edge on the speculum and slightly different bare-part colouration.
In captivity, domestic ducks come in wild-type plumages, white, and other colours. Most of these colour variants are also known in domestic mallards not bred as livestock, but kept as pets, aviary birds, etc., where they are rare but increasing in availability.
A noisy species, the male has a nasal call, and a high-pitched whistle, while the female has a deeper quack stereotypically associated with ducks.[20][21]
The mallard is a rare example of both Allen's Rule and Bergmann's Rule in birds. Bergmann's Rule, which states that polar forms tend to be larger than related ones from warmer climates, has numerous examples in birds. Allen's Rule says that appendages like ears tend to be smaller in polar forms to minimize heat loss, and larger in tropical and desert equivalents to facilitate heat diffusion, and that the polar taxa are stockier overall. Examples of this rule in birds are rare, as they lack external ears. However, the bill of ducks is very well supplied with blood vessels and is vulnerable to cold.[citation needed]
Due to the malleability of the mallard's genetic code, which gives it its vast interbreeding capability, mutations in the genes that decide plumage colour are very common and have resulted in a wide variety of hybrids such as Brewer's duck (mallard × gadwall, Anas strepera).[22]
Distribution and habitat
The mallard is widely distributed across the Northern and Southern Hemispheres, North America from southern and central Alaska to Mexico, the Hawaiian Islands, and across Eurasia, from Iceland and southern Greenland and parts of Morocco (North Africa) in the west, Scandinavia to the north, and to Siberia, Japan,and South Korea, in the east, Australia and New Zealand in the Southern hemisphere.[14] It is strongly migratory in the northern parts of its breeding range, and winters farther south. For example, in North America, it winters south to Mexico, but also regularly strays into Central America and the Caribbean between September and May.[23]
The mallard inhabits a wide range of habitat and climates, from Arctic tundra to subtropical regions. It is found in both fresh- and salt-water wetlands, including parks, small ponds, rivers, lakes and estuaries, as well as shallow inlets and open sea within sight of the coastline. Water depths of less than 1 metre (3.3 ft) are preferred, birds avoiding areas more than a few metres deep. They are attracted to bodies of water with aquatic vegetation
Behaviour
Feeding
The mallard is omnivorous and very flexible in its foods choice. Its diet may vary based on several factors, including the stage of the breeding cycle, short-term variations in available food, nutrient availability, and inter and intraspecific competition.[24] The majority of the mallard's diet seems to be made up of gastropods, invertebrates (including beetles, flies, lepidopterans, dragonflies, and caddisflies), crustaceans, worms, many varieties of seeds and plant matter, and roots and tubers. During the breeding season, male birds were recorded to have eaten 37.6% animal matter and 62.4% plant matter, most notably Echinochloa crus-galli, and nonlaying females ate 37.0% animal matter and 63.0% plant matter, while laying females ate 71.9% animal matter and only 28.1% plant matter.[25] Plants generally make up a larger part of the bird's diet, especially during autumn migration and in the winter.[26][27]
It usually feeds by dabbling for plant food or grazing; there are reports of it eating frogs. It usually nests on a river bank, but not always near water. It is highly gregarious outside of the breeding season and forms large flocks, which are known as sords.[28]
Breeding
Mallards usually form pairs (in October and November in the Northern hemisphere) only until the female lays eggs at the start of nesting season which is around the beginning of spring, at which time she is left by the male who joins up with other males to await the moulting period which begins in June (in the Northern hemisphere). During the brief time before this, however, the males are still sexually potent and some of them either remain on standby to sire replacement clutches (for female Mallards that have lost or abandoned their previous clutch) or forcibly mate with females that appear to be isolated or unattached regardless of their species and whether or not they have a brood of ducklings.
The nesting period can be very stressful for the female since she lays more than half her body weight in eggs. She requires a lot of rest and a feeding/loafing area that is safe from predators. When seeking out a suitable nesting site, the female's preferences are areas that are well concealed, inaccessible to ground predators, or have few predators nearby. This can include nesting sites in urban areas such as roof gardens, enclosed courtyards, and flower boxes on window ledges and balconies more than one story up, which the ducklings cannot leave safely without human intervention. The clutch is 8–13 eggs, which are incubated for 27–28 days to hatching with 50–60 days to fledgling. The ducklings are precocial and fully capable of swimming as soon as they hatch. However, filial imprinting compels them to instinctively stay near the mother not only for warmth and protection but also to learn about and remember their habitat as well as how and where to forage for food. When ducklings mature into flight-capable juveniles, they learn about and remember their traditional migratory routes (unless they are born and raised in captivity). After this, the juveniles and the mother may either part or remain together until the breeding season arrives.[citation needed]
When they pair off with mating partners, often one or several drakes end up left out. This group sometimes targets an isolated female duck, even one of a different species, and proceeds to chase and peck at her until she weakens, at which point the males take turns copulating with the female. Lebret (1961) calls this behaviour "Attempted Rape Flight" and Cramp & Simmons (1977) speak of "rape-intent flights". Male mallards also occasionally chase other male ducks of a different species, and even each other, in the same way. In one documented case of "homosexual necrophilia", a male mallard copulated with another male he was chasing after the chased male died upon flying into a glass window.[29] This paper was awarded with an Ig Nobel Prize in 2003.[30]
Mallards are opportunistically targeted by brood parasites, occasionally having eggs laid in their nests by Redheads, ruddy ducks, lesser scaup, gadwalls, northern shovelers, northern pintails, cinnamon teal, common goldeneyes, and other mallards. These eggs are generally accepted when they resemble the eggs of the host mallard, although the hen may attempt to eject them or even abandon the nest if parasitism occurs during egg laying.[31] Mallards of all ages (but especially young ones) and in all locations must contend with a wide diversity of predators including raptors, mustelids, corvids, snakes, raccoons, opossums, skunks, turtles, large fish and felids and canids, including domesticated ones.[32] The most prolific natural predators of adult mallards are red foxes (which most often pick off brooding females) and the faster or larger birds of prey, i.e. peregrine falcons or Haliaeetus eagles.[33][34] In North America, adult mallards face no fewer than 15 species of birds of prey, from hen harriers and short-eared owls (both smaller than a mallard) to huge bald and golden eagles, and about a dozen species of mammalian predator, not counting several more avian and mammalian predators who threaten eggs and nestlings.[31]
Mallards are also preyed upon occasionally by 'unorthodox' species, such as the Grey heron (Ardea cinerea), European herring gull (Larus argentatus) and the Northern pike (Esox lucius).
Conservation
Unlike many waterfowl, mallards have benefited from human alterations to the world. They are very adaptable, being able to live and even thrive in urban areas which may have supported more localized, sensitive species of waterfowl before development. The release of feral mallards in areas where they are not native sometimes creates problems through interbreeding with indigenous waterfowl. These non-migratory mallards interbreed with indigenous wild ducks from local populations of closely related species through genetic pollution by producing fertile offspring. Complete hybridization of various species of wild ducks gene pools could result in the extinction of many indigenous waterfowl. The wild mallard itself is the ancestor of most domestic ducks and its naturally evolved wild gene pool gets genetically polluted in turn by the domesticated and feral populations.[35][36][37]
The mallard is considered an invasive species in New Zealand.[14] There, and elsewhere, mallards are spreading with increasing urbanization and hybridizing with local relatives.[38] Over time, a continuum of hybrids ranging between almost typical examples of either species will develop; the speciation process beginning to reverse itself.[39] This has created conservation concerns for relatives of the mallard, such as the Hawaiian duck,[38][40] the A. s. superciliosa subspecies of the Pacific black duck,[38][41][42][43] the American black duck,[38][44][45][46] the mottled duck,[38][47][48] Meller's duck,[49] the yellow-billed duck,[39] and the Mexican duck,[38][48] in the latter case even leading to a dispute whether these birds should be considered a species[50] (and thus entitled to more conservation research and funding) or included in the mallard.
The availability of mallards, mallard ducklings, and fertilized mallard eggs for public sale and private ownership, either as livestock or as pets, is currently legal in the United States except for the state of Florida which has currently banned domestic ownership of mallards. This is to prevent hybridisation with the native mottled duck.[51]
Mallards are also causing severe "genetic pollution" of South Africa's biodiversity by breeding with endemic ducks, although the Agreement on the Conservation of African-Eurasian Migratory Waterbirds applies to the mallard. The hybrids of mallards and the yellow-billed duck are fertile and can produce more hybrid offspring. If this continues, only hybrids will occur and in the long term this will result in the extinction of various indigenous waterfowl. The mallard duck can cross breed with 63 other species and is posing a severe threat to the genetic integrity of indigenous waterfowl. Mallards and their hybrids compete with indigenous birds for resources such as food, nest sites and roosting sites.[37]
The Eastern or Chinese spot-billed duck is currently introgressing into the mallard populations of the Primorsky Krai, possibly due to habitat changes from global warming.[13] The Mariana mallard was a resident allopatric population—in most respects a good species—apparently initially derived from mallard-Pacific black duck hybrids;[52] unfortunately, it became extinct in the late twentieth century.[53]
The Laysan duck is an insular relative of the mallard with a very small and fluctuating population. Mallards sometimes arrive on its island home during migration, and can be expected to occasionally have remained and hybridized with Laysan ducks as long as these species have existed. But these hybrids are less well adapted to the peculiar ecological conditions of Laysan Island than the local ducks, and thus have lower fitness, and furthermore, there were—apart from a brief time in the early 20th century when the Laysan duck was almost extinct—always many more Laysan ducks than stray mallards. Thus, in this case, the hybrid lineages would rapidly fail.[citation needed]
In the cases mentioned above, however, ecological changes and hunting have led to a decline of local species; for example, the New Zealand grey duck population declined drastically due to overhunting in the mid-20th century.[43] Hybrid offspring of Hawaiian ducks seem to be less well-adapted to native habitat, and utilizing them in reintroduction projects apparently reduces success.[38][54] In summary, the problems of mallards "hybridizing away" relatives is more a consequence of local ducks declining than of mallards spreading; allopatric speciation and isolating behaviour have produced today's diversity of mallard-like ducks despite the fact that in most if not all of these populations, hybridization must have occurred to some extent.[citation needed]
Relationship with humans
The mallard is depicted in a marginal decoration of the 15th century English illuminated manuscript the Sherborne Missal.[55]
Since 1933, the Peabody Hotel in Downtown Memphis, Tennessee has maintained a long tradition of keeping one mallard drake and four mallard hens, called The Peabody Ducks, as a popular hotel attraction and as guests of honour. The mallards are provided by a local farmer and friend of the Peabody Hotel and are rotated out and returned to the farm for a new team of mallards every three months. This tradition has also been maintained and observed at the other Peabody Hotels in Little Rock, Arkansas and Orlando, Florida.[56]
Although mallard do not have as fine a flavour as teal, they have the advantage of being one of the larger ducks, so are selected for breeding for shooting and the table.[57] Shot sizes four and five are recommended for a clean and efficient kill in shooting mallard.[58]
The children's picture book Make Way for Ducklings, published in 1941 and winner of the 1942 Caldecott Medal for its illustrations, is the story of a pair of mallards who decide to raise their family on an island in the lagoon in Boston Public Garden in Massachusetts.[59]
Duck Head, a U.S. clothing brand, uses the image of a mallard's head as its logo.
One can certainly see the cat in this Bobcat... This one was playfully stalking and pouncing on its brother/sister, so much
like the behaviour of the pet cats many of us have :))
I had the enjoyable opportunity to visit Bay Beach Wildlife Sanctuary in Green Bay, Wisconsin.
A 700 acre park nestled in the city on the shore of the Green Bay, this sanctuary takes in injured wildlife and releases them back into the wild when possible. Those that can't fend for themselves in the wild, are lovingly cared for there the rest of their lives. Some are on display to the public for educational purposes, allowing people to appreciate and experience wildlife that is native to Wisconsin.
Not what I had expected to be shooting yesterday although I do suppose it qualifies as "wild life". An amazing experience watching this guy navigate the rapids.
