The Plum-throated Cotinga is a spectacularly-colored member of the genus Cotinga that ranges throughout western Amazonia, including eastern Ecuador and southeastern Colombia, south through eastern Peru and western Brazil to northern Bolivia. Males in the genus Cotinga are characteristically bright blue, and the stunning male Plum-throated is uniformly turquoise blue with black primaries, and a “plum-colored” purple throat. This species overlaps in range with the similar Spangled Cotinga (Cotinga cayana), but differs by males lacking the extensive black scalloping on the wings and back that is present in Spangled. Eye color in both sexes is yellow (compared to dark in Spangled), which is useful in discerning the very similar-plumaged females. Plum-throated is also found more in the canopy of varzea forest, or along the edge of oxbow lakes, while Spangled is typically restricted to the canopy of terra firme forest. Amazingly, not known to vocalize, but males emit a “whistling sound” from the wings in flight.
