The two Asiatic species are the blue or Indian peafowl originally from the Indian subcontinent , and the green peafowl from Southeast Asia. The Congo peafowl , native only to the Congo Basin , is not a true peafowl. Male peafowl are known for their piercing calls and their extravagant plumage. The latter is especially prominent in the Asiatic species, which have an eye-spotted "tail" or "train" of covert feathers , which they display as part of a courtship ritual.
