The male (peacock) Indian Peafowl has iridescent blue-green or green colored plumage. The peacock tail (“train”) is not the tail quill feathers but the highly elongated upper tail coverts. The “eyes” are best seen when the peacock fans its tail. Both species have a crest atop the head. The female (peahen) Indian Peafowl has a mixture of dull green, brown, and grey in her plumage. She lacks the long upper tail coverts of the male but has a crest. The female can also display her plumage to ward off female competition or signal danger to her young.
