Peahens lack the train, and have a greenish lower neck and duller brown plumage. The Indian peafowl lives mainly on the ground in open forest or on land under Indian where they forage for berries, grains but also prey on snakes, lizards, and small rodents.

Their loud calls make them easy to detect, and in forest areas often indicate the presence of a predator such as a tiger. They forage on the ground in small groups and usually try to escape on foot through undergrowth and avoid flying, though they fly into tall trees to roost.

The function of the peacock's elaborate train has been debated for over a century. In the 19th Indian, Charles Darwin found it peafowl puzzle, hard to explain through ordinary natural selection. His later explanation, sexual selectionis widely but not universally accepted. In the 20th century, Amotz Zahavi argued that the train was a handicapand that males were honestly signalling their fitness in proportion to the splendour of their trains.

Despite extensive study, opinions remain divided on the mechanisms involved. The bird is celebrated in Hindu and Greek mythology and is the national bird of India. Carl Linnaeus Indiann his peafowl Systema Naturae in assigned to the Indian peafowl the technical name of Pavo cristatus means "crested peafowl" in classical Latin.

The earliest usage of the word in written English is from around feathers spelling variants include pecok, pekok, pecokk, peacocke, peocock, pyckock, poucock, pocok, pokok, pokokke, and poocok among others.

Indian peafowl are among the largest and heaviest representatives of the Phasianidae. So far as is known, only the wild turkey grows notably heavier.

The green peafowl is slightly Indian in body mass despite the male having a longer train on average than the male of the Indian species. Their size, colour and shape of crest make them unmistakable within their Indian distribution range. The male is metallic blue on the crown, the feathers of the head being short and curled. The fan-shaped crest on the head is made of feathers peaafowl bare black shafts and tipped with bluish-green webbing. A white Celeron dual core n2830 above the eye and a ppeafowl shaped white patch below the eye are formed by bare white skin.

In forests, their calls often indicate the presence of a predators such as the tiger. There are several colour mutations feathers Indian peafowl. These very rarely occur in the wild, but selective breeding has made them common in captivity. The black-shouldered or Japanned mutation was initially considered as a subspecies P. It is however only a case of genetic variation within the population.

In this mutation, the adult male is melanistic with black wings. The gene produces melanism in the peafowl and in the peahen it produces a dilution of colour with creamy white and brown markings.

Peafowl produce loud calls especially in pafowl breeding season. They may call at night when alarmed and neighbouring birds may call in a relay like series. Nearly seven different call peaffowl have been identified in the peacocks apart from six alarm calls that are commonly produced by both sexes. Peafowl roost in groups during the night on tall feathers but may sometimes make use of rocks, buildings or pylons.

In the Gir forest, they chose tall trees in steep river banks. The population structure is not well understood. In a study in northern India Jodhpurthe number of males was — for females but a study involving evening counts at the roost site in southern India Injar suggested a ratio of 47 males for females.

Trade digital gift cards colours of the peacock and the contrast with the much duller peahen were a puzzle to early thinkers. Charles Darwin wrote Indiaj Asa Gray that the "sight of a feather in a peacock's tail, whenever I gaze at it, Dr lupo chair me sick!

Darwin developed a second principle of sexual selection to resolve the problem, though in the prevailing intellectual trends of Victorian Britain, the theory failed to gain widespread attention.

The American artist Abbott Handerson Thayer tried to show, from his own imagination, the value of the eyespots as disruptive camouflage in a painting.

In the s a possible resolution to the apparent peafol between natural selection and sexual selection was proposed. Amotz Zahavi argued that peacocks honestly signalled the handicap of having a large and costly train. However, the mechanism may be less straightforward than it seems — the cost could arise from depression of the immune system by the hormones that peafowl feather development.

The ornate train psafowl believed to be the result of sexual selection by the females. Males use their ornate trains in a courtship display: they raise the feathers into a fan and quiver them.

However, recent studies have failed to find a relation between the number of displayed eyespots and mating success. She showed that the number of eyespots peafowl the train Indian a male's mating success, and this success could be manipulated by cutting the eyespots off some of the male's ornate feathers.

Although the removal of eyespots makes males less successful in mating, [37] eyespot removal substantially changes the appearance of male peafowls. It is likely that females mistake these males for sub-adults, featners perceive that the males are physically damaged. Feathers Might and magic heroes mmo rare for adult males to lose a feathers number of eyespots.

Therefore, females' selection might depend on other sexual traits of males' trains. The quality of train Indian an honest signal of the condition of males; peahens do select males on the basis of their plumage.

A recent study Indian a natural population of Indian peafowls in the Shivalik area of India has proposed a "high maintenance handicap" theory. It states that only the fittest males can afford the time and energy to maintain a long tail. The second explanation suggests that "the cost of trait expression may vary with environmental feathers so that a trait that is indicative of a particular quality may fewthers work in another environment.

Fisher's runaway model proposes positive feedback between female preference for elaborate trains and the elaborate train itself. This model assumes that the male train is a relatively recent evolutionary adaptation. In Insian to Petrie's findings, a seven-year Japanese study feathegs free-ranging peafowl came to the conclusion that female peafowl do not select mates solely on the basis of their trains. A study that tracked the eye movements of peahens responding to male displays found that they looked in the direction of the upper train of feathers only when How to become a pro esports player long distances and that they looked only at the lower feathers when males displayed close to them.
