* Argus, king of Argos, had one hundred eyes, of which two only were asleep at one time. Juno put the eyes of Argus on the tail of the Peacock, a bird sacred to her divinity.
Tail of twelve feathers, mid pair elongated. Most typical form of Pheasant wing where first primary is shortest and tenth longest. Secondary quills largely developed, marked with ocelli, and longer than primaries in both sexes. Sides of face, throat, and foreneck naked. Short hairy occipital crest. No spurs. These birds never live in pairs, the female visiting the male.
