Black-and-gold Cotinga

The black-and-gold cotinga is 25 to 28 cm (9.8 to 11 in) long. The sexes are strongly sexually dimorphic. Adult males are entirely black but for a large golden yellow patch on the wing's flight feathers (remiges). They have a reddish brown iris, a bright orange bill with a slight hook on the end, and dark brown legs and feet. Females are overall dull olive-green which is yellower on the edges of the flight feathers and belly. They much resemble the monomorphic grey-winged cotinga (L. condita) and their ranges overlap. Their bill is a duller orange than the male's. Voice: The black-and-gold cotinga's song is a "curious high, sharp, eerie suuuuuwíii, increasing in strength upslurred midway". Two or more males alternate vocalizing from treetops, producing a continuous sound that carries a long distance.
