Peafowl is a common name for three species of birds in the genera Pavo and Afropavo of the Phasianidae family, the pheasants and their allies. The Male peafowl is referred to as peacocks and female peafowl as peahens. The two Asiatic species are the blue or Indian peafowl originally of the Indian subcontinent, and the green peafowl of Southeast Asia; the one African species is the Congo peafowl, native only to the Congo Basin. The Male peafowl is known for their piercing calls and their extravagant plumage. The latter is especially prominent in the Asiatic species, which have an eye-spotted "tail" and "train" of covert feathers, which they display as part of a courtship ritual.
Peafowl is an omnivore and eats mostly plant parts, flower petals, seed heads, insects and other arthropods, reptiles, and amphibians. the wild peafowl looks for their food scratching around in leaf litter either early in the morning or at dusk. They retreat to the shade and security of the woods for the hottest portion of the day. These birds are not picky and will eat almost anything they can fit in their beak and digest. They actively hunt insects like ants, crickets and termites; millipedes; and other arthropods and small mammals. The Indian peafowl also eats big and little snakes.
Domesticated peafowl may also eat bread and cracked grain such as oats and corn, cheese, cooked rice and sometimes cat food. It has been noticed by keepers that peafowl enjoys protein-rich food including larvae that infest granaries, different kinds of meat and fruit, as well as vegetables including dark leafy greens, broccoli, carrots, beans, beets, and peas and a tarantula. In that episode, a pair of Ornithomimus were looking for apples and peafowl to release. One caught an apple but he liked the taste. Then they encounter and are scared off by a Gigantopithecus.
Then Allen released the peacocks into the aviary.
