The Guianan Cock-of-the-rock (Rupicola rupicola) is a South American passerine about 30 cm (12 in) in length. The bright orange male has a prominent half-moon crest, which is used is competitive displays in lek gatherings to attract a female. Although the Guianan cock-of-the-rock sometimes munches on small vertebrates and insects, its diet is mainly composed of fruit –and a study found that up to 75% of the fruit eaten by this bright orange South American bird is either red or black coloured.
