The cocks-of-the-rock, which compose the genus Rupicola, are large cotingid birds native to South America. The Andean cock-of-the-rock and the smaller Guianan cock-of-the-rock exhibit sexual dimorphism: the males are bright orange or red with a prominent fan-shaped crests; the females are overall brownish with hints of the bright colours of the males. Females build nests on rocky cliffs or large boulders, and raise the young on their own. The Guianan cock of the rock has a red eye – the Andean has a white eye.
