Oreotrochilus adela (Wedge-tailed Hillstar)

Wikipedia Abstract

The wedge-tailed hillstar (Oreotrochilus adela) is a species of hummingbird in the Trochilidae family. This sexually dimorphic species is found in scrub and woodland at altitudes of 2,600 to 4,000 metres (8,500 to 13,100 ft) in the Andes of Bolivia and far north-western border region of Argentina. It is threatened by habitat loss. Uniquely among the hillstars, the flanks of the male are deep chestnut, while the underparts of the female are orange-buff.
