Peacocks are large, colorful pheasants (typically blue and green) known for their iridescent tails.
These tail feathers, or coverts, spread out in a distinctive train that is more than 60 percent of the bird’s total body length and boast colorful “eye” markings of blue, gold, red, and other hues. The large train is used in mating rituals and courtship displays. It can be arched into a magnificent fan that reaches across the bird’s back and touches the ground on either side. Females are believed to choose their mates according to the size, color, and quality of these outrageous feather trains. The Peacocks brilliant ‘train’ contains over 200 shimmering feathers, each one decorated with eyespots. The male Indian Peacock has iridescent colouring of blue and green on its head, neck and breast. Their long ‘trains’ are not the tail quill feathers but elongated upper tail feather coverts. The train is bronze and green and has a series of ‘eyes’ which are more prominent when the tail is fanned. The male Indian Peafowls actual tail feathers are short and grey in colour and can only be seen from behind when the tail is extended and fully fanned. The males display their beautiful fanned trains as part of their courtship behaviour to the Peahens. During molting season, the males shed their train feathers and their grey quill feathers are more obvious.
