They have a deep red iris, a bill with an ivory-white or pale gray base and blackish gray tip, and black or dark gray legs and feet. Voice: The red-crested cotinga's song has been described as "a stuttered series of deep notes ending in a short croak: ke-ke-ke-kerrr" and as "a frog-like k-k-k-k-k-rrrréh". Its calls are "a deep chucking note and a deep, croaking, crek".
