The Indian peacock has iridescent blue and green plumage, mostly metallic blue and green, but the green peacock has green and bronze body feathers. In both species, females are a little smaller than males in terms of weight and wingspan, but males are significantly longer due to the “tail”, also known as a “train”. The peacock train consists not of tail quill feathers, but highly elongated upper tail coverts. These feathers are marked with eyespots, best seen when a peacock fans his tail.
