Peafowl include two Asiatic species (the blue or Indian peafowl originally of India and Sri Lanka and the green peafowl of Burma, Indochina, and Java) and one African species (the Congo peacock native only to the Congo Basin) of bird in the genus Pavo and Afropavo of the phasianidae family, the pheasants and their allies, known for the male's piercing call and, among the Asiatic species, his extravagant eye-spotted tail covert feathers which he displays as part of a courtship ritual. The male is properly called a peacock, the female a peahen, and the immature offspring peachicks. The adult female green peahen is coloured similarly to the male, whilst that of the Indian and African varieties is dull grey and/or brown. Peachicks of both sexes vary in colour between yellow and tawny usually with patches of darker brown or light tan and "dirty white" ivory.In common with other members of the galliformes, peacocks possess metatarsal spurs or "thorns" on their legs used during intraspecific territorial fights.
