From the pheasant family of birds, peacocks are the male version of the group known as peafowl (the females are called peahens), and are famous for their large courting display of billowing tail feathers covered in blue-green "eyes."
INDIAN PEACOCKS
The peacocks of the species display the famous tail plumage used in courting rituals and have bright, blue heads and crest colorings. The bright coloring and large tail feathers are used to attract peahens and size up against other peacocks.
GREEN PEACOCKS
Green peacocks are similar to Indian peacocks in that they have large, brightly colored trains and use the feathers in courting rituals. The heads and crests of green peacocks are a deep green color rather than blue, making them distinguishable from Indian peacocks
