Wedge-tailed Hillstar Oreotrochilus adela


Treated as Near Threatened by BirdLife International, the Wedge-tailed Hillstar was formerly considered endemic to southern Bolivia, but has, like several other Bolivian ‘endemics’ recently been found in extreme northwestern Argentina. In common with other hillstars, both sexes possess greenish-brown upperparts. Males are further characterized by their green throat, black line down the central underparts bordered by chestnut, and rufous and black tail, whereas females are orange below with a gray-spotted throat pattern, and also possess white on some tail tips. Like other hillstars, the Wedge-tailed Hillstar is an inhabitant of relatively open high-altitude habitats, reaching up to 4000 m above sea level.
