The primary flight feathers are bright chestnut. Its brown eye is surrounded by bare bluish gray skin. The legs are pale blue. Voice: The rufous-headed chachalaca is most vocal from before dawn into the early morning. Its principal call is a "raucous, repeated 'kwak-ar-ar-ar', 'cha-cha-kaw' or shriller 'kra-kra-kra'", and is usually initiated by the male. Pairs give several calls "including a soft cooing or clucking, harsh 'cow', and fast, repeated 'kawuck'."
