Peafowl is a common name for three bird species in the genera Pavo and Afropavo within the tribe Pavonini of the family Phasianidae, the pheasants and their allies. Male peafowl are referred to as peacocks, and female peafowl are referred to as peahens, even though peafowl of either sex are often referred to colloquially as "peacocks".
Hybrids between Indian peafowl and Green peafowl are called Spaldings, after the first person to successfully hybridise them, Mrs. Keith Spalding. Unlike many hybrids, spaldings are fertile and generally benefit from hybrid vigour; spaldings with a high-green phenotype do much better in cold temperatures than the cold-intolerant green peafowl while still looking like their green parents. Plumage varies between individual spaldings, with some looking far more like green peafowl and some looking far more like blue peafowl, though most visually carry traits of both.
In addition to the wild-type "blue" colouration, several hundred variations in colour and pattern are recognised as separate morphs of the Indian Blue among peafowl breeders. Pattern variations include solid-wing/black shoulder (the black and brown stripes on the wing are instead one solid colour), pied, white-eye (the ocelli in a male's eye feathers have white spots instead of black), and silver pied (a mostly white bird with small patches of colour). Colour variations include white, purple, Buford bronze, opal, midnight, charcoal, jade, and taupe, as well as the sex-linked colours purple, cameo, peach, and Sonja's Violeta. Additional colour and pattern variations are first approved by the United Peafowl Association to become officially recognised as a morph among breeders. Alternately-coloured peafowl are born differently coloured than wild-type peafowl, and though each colour is recognisable at hatch, their peachick plumage does not necessarily match their adult plumage.
Occasionally, peafowl appear with white plumage. Although albino peafowl do exist,[citation needed] this is quite rare, and almost all white peafowl are not albinos; they have a genetic condition called leucism, which causes pigment cells to fail to migrate from the neural crest during development. Leucistic peafowl can produce pigment but not deposit the pigment to their feathers, resulting in their blue-grey eye colour and the complete lack of colouration in their plumage. Pied peafowl are affected by partial leucism, where only some pigment cells fail to migrate, resulting in birds that have colour but also have patches absent of all colour; they, too, have blue-grey eyes. By contrast, true albino peafowl would have a complete lack of melanin, resulting in irises that look red or pink. Leucistic peachicks are born yellow and become fully white as they mature.
As with many birds, vibrant iridescent plumage colours are not primarily pigments, but structural colouration. Optical interference Bragg reflections, based on regular, periodic nanostructures of the barbules (fiber-like components) of the feathers, produce the peacock's colours. More specifically, there are 2D photonic-crystal structures that are within the layers or surface area of those various barbules, which are essentially in charge of the colouration of their feathers. Slight changes to the spacing of these barbules result in different colours. Brown feathers are a mixture of red and blue: one colour is created by the periodic structure and the other is created by a Fabry–Pérot interference peak from reflections from the outer and inner boundaries. Such structural colouration causes the iridescence of the peacock's hues. Color derived from physical structure rather than pigment can vary with viewing angle. Most commonly, during a courtship display, the visiting female peahen will stop directly in front of the male peacock – thus providing her the ability to assess the male at 90° to the surface of the feather. Then, the male will turn and display his feathers about 45° to the right of the sun's azimuth which allows the sunlight to accentuate the iridescence of his train. If the female chooses to interact with the male, he will then turn to face her and shiver his train so as to begin the mating process.
Peafowl are omnivores and mostly eat plants, flower petals, seed heads, insects and other arthropods, reptiles, and amphibians. Wild peafowl look for their food scratching around in leaf litter either early in the morning or at dusk. They retreat to the shade and security of the woods for the hottest portion of the day. These birds are not picky and will eat almost anything they can fit in their beak and digest. They actively hunt insects like ants, crickets and termites; millipedes; and other arthropods and small mammals.[28] Indian peafowl also eat small snakes.
Domesticated peafowl may also eat bread and cracked grain such as oats and corn, cheese, cooked rice and sometimes cat food. It has been noticed by keepers that peafowl enjoy protein-rich food including larvae that infest granaries, different kinds of meat and fruit, as well as vegetables including dark leafy greens, broccoli, carrots, beans, beets, and peas.
The peafowl is native to India and significant in its culture. In Hinduism , the Indian peacock is the mount of the god of war, Lord Kartikeya , and the warrior goddess Kaumari, and is also depicted around the goddess Santoshi. During a war with Asuras, Kartikeya split the demon king Surapadman in half. Out of respect for his adversary's prowess in battle, the god converted the two halves into an integral part of himself. One half became a peacock serving as his mount, and the other a rooster adorning his flag. The peacock displays the divine shape of Omkara when it spreads its magnificent plumes into a full-blown circular form. Peacock feathers also adorn the crest of Lord Krishna, an avatar of Lord Vishnu, one of the trimurti.
Chandragupta Maurya, the founder of the Mauryan Empire, was born an orphan and raised by a family farming peacocks. According to the Buddhist tradition, the ancestors of the Maurya kings had settled in a region where peacocks (mora in Pali) were abundant. Therefore, they came to be known as "Moriyas", literally, "belonging to the place of peacocks". According to another Buddhist account, these ancestors built a city called Moriya-nagara ("Moriya-city"), which was so called, because it was built with the "bricks coloured like peacocks' necks". After conquering the Nanda Empire and defeating the Seleucid Empire, the Chandragupta dynasty reigned uncontested during its time. Its royal emblem remained the peacock until Emperor Ashoka changed it to a lion, as seen in the Lion Capital of Ashoka, as well in his edicts. The peacock continued to represent elegance and royalty in India during medieval times; for instance, the Mughal seat of power was called the Peacock Throne.
The peacock is represented in both the Burmese and Sinhalese zodiacs. To the Sinhalese people, the peacock is the third animal of the zodiac of Sri Lanka.
Peacocks (often a symbol of pride and vanity) were believed to deliberately consume poisonous substances in order to become immune to them, as well as to make the colours of their resplendent plumage all the more vibrant – seeing as so many poisonous flora and fauna are so colourful due to aposematism, this idea appears to have merit. The Buddhist deity Mahamayuri is depicted seated on a peacock. Peacocks are seen supporting the throne of Amitabha, the ruby red sunset coloured archetypal Buddha of Infinite Light.
India adopted the peacock as its national bird in 1963 and it is one of the national symbols of India.
