The White-vented Plumeleteer (Chalybura buffonii) is a species of hummingbird in the Trochilidae family.
It is found in Colombia, Ecuador, Panama, Peru, and Venezuela.
Its natural habitats are subtropical or tropical dry forests, subtropical or tropical moist lowland forests, and heavily degraded former forest.
A large hummingbird, the white-vented plumeleteer measures about 12 cm (4.7 in). The male has a metallic green body, dark wings and a blue-black tail. The namesake feature is a large patch of white undertail coverts. Bill is entirely black, as are the feet. He is easily confused with the similar bronze-tailed plumeleteer. The female is similar, but has an entirely white belly, chest and chin.[2]
