Indian Peacock

About

The male Indian Peafowl, commonly known as the peacock, is one of the most recognizable birds in the world. These large, brightly colored birds have a distinctive crest and an unmistakable ornamental train. The train (1.4-1.6 meters in length) accounts for more than 60% of their total body length (2.3 meters). Combined with a large wingspan (1.4-1.6 meters), this train makes the male peafowl one of the largest flying birds in the world. The train is formed by 100-150 highly specialized uppertail-coverts. Each of these feathers sports an ornamental ocellus, or eye-spot, and has long disintegrated barbs, giving the feathers a loose, fluffy appearance. When displaying to a female, the peacock erects this train into a spectacular fan, displaying the ocelli to their best advantage.

The more subtly colored female Peafowl is mostly brown above with a white belly. Her ornamentation is limited to a prominent crest and green neck feathers. Though females (2.75-4.0 kg) weigh nearly as much as the males (4.0-6.0 kg), they rarely exceed 1.0 meter in total body length.


National Insignia
The Indian peacock,Pavo cristatus (Linnaeus), the national bird of India, is a colourful, swan-sized bird, with a fan-shaped crest of feathers, a white patch under the eye and a long, slender neck.

The peacock is widely found in the Indian sub-continent from the south and east of the Indus river, Jammu and Kashmir, east Assam, south Mizoram and the whole of the Indian peninsula. The peacock enjoys immense protection. It is fully protected under the Indian Wildlife Protection) Act, 1972.
