The Peacock, commonly male Indian Peafowl, 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 Peacock one of the largest flying birds in the world. The train is formed by 100-150 highly specialized upper tail-coverts. Each of these feathers sports an ornamental oculus, or eyespot, 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 celli to their best advantage.
