Peafowl are three Asiatic species of flying bird in the genus Pavo of the pheasant family, Phasianidae, best known for the male's extravagant eye-spotted tail, which it displays as part of courtship. The male is called a peacock, the female a peahen, and the offspring peachicks. The male (peacock) Indian Peafowl has iridescent blue-green or green colored plumage. The peacock tail ("train") is not the tail quill feathers but the highly elongated upper tail covert feathers. The "eyes" are best seen when the peacock fans its tail. Like a cupped hand behind the ear, the erect tail-fan of the male helps direct sound to the ears. Both species have a crest atop the head.
