The Guianan cock-of-the-rock (Rupicola rupicola) generic and specific names are derived from the Latin words rupes "rock" or "cliff", and cola "inhabiting", which express its habit of nesting on rock walls.
The Guianan cock-of-the-rock's large fan-like crest almost completely obscures a male cock-of-the-rock’s bill. The crest is formed by two rows of feathers that meet to form a semicircle. It lives across the forested region of northeastern South America. Its diet consists mostly of fruit, but they sometimes feast on small snakes and lizards. Males are mostly intensely orange. In the Andean species, males have grey and black wing feathers and a black tail. Guianan males have orange and black wings and tail, with long fringes on some of the orange feathers. Females are chestnut-brown (in Andeans) or smoky-brown with greyish heads (in Guianans). The Guianan cock-of-the-rock lives in humid forests of South America, too, but its distribution is more northerly, including parts of French Guiana, Guyana, Suriname, Venezuela, northern Brazil, and western Colombia.
