Complete answer:
The Indian peacock, Pavo cristatus, is a colourful, swan-sized bird with a fan-shaped crest of feathers, a white patch beneath the eye, and a long, thin neck. It is India's national bird. The Indian peafowl (Pavo cristatus) is a peafowl species native to the Indian subcontinent. It is also known as the common peafowl and blue peafowl.
It has been adopted in a number of other countries. Sexual dimorphism is noticeable in Indian peafowl. The peacock has a brightly coloured crest of spatula-tipped wire-like feathers and is best recognised for its long train of extended upper-tail covert feathers with colourful eyespots. During courtship, these stiff feathers are lifted into a fan and quivered in a show.
Peacocks are capable of flight despite the length and bulk of their covert feathers. During courtship, these stiff feathers are lifted into a fan and quivered in a show. Peahens lack the train and have a drab brown plumage with a white face and iridescent green lower neck. The Indian peafowl forages for berries and grains on the ground in open woodland or on cultivated land, but they also hunt on snakes, lizards, and small rodents. Their powerful calls make them easy to spot in the jungle, and they frequently signal the presence of a predator like a tiger.
