Pavo cristatus
The blue peacock has spectacular colours. The male’s plumage is particularly bright. The head, neck and breast are blue-green and purple with a metallic sheen. There is a bare patch around the eyes, and a crest of feathers, with barbs at their tips, embellishes the crown. The fairly large beak is light brown as is the iris. The back feathers are golden green with bronze edges. The feathers above the tail ranging from 100 to 150 are much longer and form the peacock’s train. These feathers can reach 1.5 metres in length. They have long metallic green barbs with blue and bronze hues, forming a mark, near the tip, evocative of an eye and known as an eyespot, the bright blue centre of which is surrounded by brown, golden yellow and purple concentric rings. The peahen is smaller than the peacock. It has no train and its plumage is not as bright.
It is found in forests and along rivers, as well as along the edges of clearings in hot and humid regions; in the mountains in southern India, it inhabits tropical humid forests where trees and bushes are sparse, up to an altitude of 2,000 metres.
The period of reproduction lasts throughout the spring. The peahen lays 4 or 5 eggs and the incubation period lasts from 28 to 30 days.
