The purple-backed sunbeam is a bird species in the family Trochilidae. It is found only in Peru.
Region
Andes Mountains
Typical Environment
Endemic to northwestern Peru in the inter-Andean valleys of the Marañón drainage. It occupies arid to semi-humid montane scrub, open woodland, ravines, and edges of upper Andean forests. The species often forages along slopes with flowering shrubs and small trees, and may utilize Eucalyptus groves where native nectar sources are sparse. It is sensitive to habitat conversion, overgrazing, and fire, which reduce the availability of key flowering plants.

The Purple-backed Sunbeam is a Peruvian hummingbird restricted to a small stretch of inter-Andean valleys. Its mantle flashes a rich violet-purple when struck by direct sunlight, giving the species its name. It has adapted to feed at both native Andean shrubs and introduced Eucalyptus blossoms, which can provide important nectar in altered landscapes. Habitat loss and degradation remain its primary threats.
