Green-and-white Hummingbird

The green-and-white hummingbird is 10 to 11 cm (3.9 to 4.3 in) long. Males weigh about 6.0 g (0.21 oz) and females about 5.5 g (0.19 oz). Both sexes have a medium length straight bill with a blackish maxilla and a reddish mandible with a dark tip. Adult males have brilliant green to bronze-green upperparts and flanks. Their undersides are whitish from the chin to the undertail coverts with greenish spots on the sides of the chin and throat and sometimes some golden-green on the coverts. Their tail is grayish green to golden green. Adult females are very similar to males, but with a light cream chin and throat that are more heavily spotted. Juveniles are similar to adult females with the cream of the throat extending to the belly.

The green-and-white hummingbird is found on the east slope of the Peruvian Andes discontinuously from Huánuco Department south to Cuzco, including at Machu Picchu. It inhabits the edges and clearings of mature subtropical forest and also secondary forest between the elevations of 1,000 and 2,500 m (3,300 and 8,200 ft).

The white-bellied hummingbird forages for nectar at a variety of flowering plants, shrubs, and trees, though its diet is not known in detail. In addition to nectar it feeds on small arthropods.
