Peafowl are large, ground dwelling birds. Adult males possess a large, ornate train of long feathers covered with an eye-like pattern. This train can extend well over a yard, and is displayed  in courtship rituals. Birds of both sexes have a crest of upright feathers on the crown of their heads. Male birds are called peacocks, and females are peahens. Males mate with multiple females, and they perform dramatic displays of their train, fanning it into a semicircle while vibrating the feathers to produce a rustling sound. They are highly vocal, particularly during the breeding season, emitting loud, distinctive calls that serve to attract mates and signal territorial presence. Breeding occurs in the warmer months, typically from spring through summer. Females lay 3 to 6 eggs in shallow ground nests, which they incubate for about 27 to 30 days. After hatching, the chicks are capable of walking and feeding within hours, and are reared solely by the female.
