The Guianan Red-Cotinga is a handsome cotinga of lowland forest canopy in the Guianas, southeastern Venezuela, and northeastern Brazil. Males call and display at dispersed leks of several individuals. During the display flight, they produce a whistle with their wings, followed by a vocal whistle. More commonly heard, however, is a whistled, three-note advertising call. Food is perhaps entirely fruit, obtained from perches or during aerial sallies. The Guianan Red-Cotinga apparently overlaps geographically with the closely related Black-necked Red-Cotinga (Phoenicircus nigricollis) along the lower Rio Tapajós. That species is similar, but is blacker above and differs in vocal characters.
