Yellow-billed Cotinga is one of the three “white” cotingas in the genus Carpodectes and is endemic to southwestern Costa Rica and adjacent western Panama. The male closely resembles the mostly white male Snowy Cotinga (Carpodectes nitidus) of the Caribbean slope (Honduras, Costa Rica and Panama), but differs by having a yellow bill and a slightly grayer crown. The females of the two species also are very similar: they are gray above, white below, with distinct white wingbars and edging to the flight feathers and a rather bold white eyering on a plain gray face. The two species mainly differ in bill coloration, with Yellow-billed having a yellow base to the bill. Yellow-billed Cotinga is a bird of two habitats, using mangroves for nesting, foraging and roosting, and lowland evergreen forests for foraging. It is unlikely to overlap in range with Snowy Cotinga, which favors tall forest and forest edge in the Caribbean lowlands. Yellow-billed Cotinga is IUCN Endangered with a small declining population and restricted range, benefiting from habitat protection and restoration in public and private protected areas.
