The Indian peafowl (Pavo cristatus) is a brightly-colored bird that lives mainly on the ground. Its loud calls make it easy to detect, and in forest areas often indicates the presence of a predator such as a tiger. The bird is celebrated in Hindu and Greek mythology and is the national bird of India.
The male Indian peafowl (peacock) is brightly colored, with a predominantly blue fan-like crest of spatula-tipped wire-like feathers, and is best known for the long train (tail) made up of elongated upper-tail covert feathers which bear colorful eyespots. These stiff feathers are raised into a fan and quivered in a display during courtship. Despite the length and size of these covert feathers, peacocks are still capable of flight. Females (peahens) lack the train and have a greenish lower neck and duller brown plumage. Downy chicks are pale buff with a dark brown mark on the nape that connects with the eyes. Young males look like the females but their wings are chestnut colored.
Indian peafowl are resident breeders across the Indian subcontinent and inhabit the drier lowland areas of Sri Lanka. They are found in moist and dry-deciduous forests near water, in montane forests, and can also adapt to live in cultivated regions and around human habitations.
Indian peafowl live mainly on the ground where they forage in small groups that usually have a cock and 3 to 5 hens. After the breeding season, the groups tend to be made up only of females and young. They are found in the open early in the morning and tend to stay in cover during the heat of the day. Indian peafowl often dust-bathe and at dusk and groups walk in single file to a favorite waterhole to drink. When disturbed, they usually escape by running and rarely take to flight. During the night, peafowl roost in groups on tall trees but may sometimes make use of rocks, buildings, or pylons. Birds arrive at dusk and call frequently before taking their position on the roost trees. Indian peafowl produces loud calls, especially in the breeding season. They may call at night when alarmed and neighboring birds may call in a relay-like series. The most common calls are a loud 'pia-ow' or 'may-awe'. They also make many other calls such as a rapid series of 'ka-aan..ka-aan' or a rapid 'kok-kok'. They often emit an explosive low-pitched honk! when agitated.
Indian peafowl are polygynous (one male to several females), and their breeding season usually depends on the rain. The peak season in southern India is April to May, January to March in Sri Lanka, and June in northern India. During this time several males may congregate at a lek site and these males are often closely related. Males at lek appear to maintain small territories next to each other and they allow females to visit them and make no attempt to guard harems. Females do not appear to favor specific males. The males display in courtship by raising the upper-tail coverts into an arched fan. The wings are held half open and drooped and it periodically vibrates the long feathers producing a ruffling sound. The cock faces the hen initially and struts and prances around and sometimes turns around to display the tail. Males may also freeze over food to invite a female in a form of courtship feeding. Males may display even in the absence of females. When a male is displaying, females do not appear to show any interest and usually continue their foraging. Indian peafowl nest on the ground; it is a shallow scrape lined with leaves, sticks, and other debris. The clutch consists of 4-8 fawn-to-buff white eggs which are incubated only by the female for about 28 days. The chicks are precocial (fully developed) and follow the mother around soon after hatching. Downy young may sometimes climb on their mother's back and she may carry them in flight to a safe tree branch. The chicks can fly about one week after hatching and become self-sufficient in 8 weeks. They usually reach reproductive maturity at the age of 2 to 3 years old.
