Plain and often confusing hummingbird found along lower to middle slopes of the Andes. Note its limited range in the eastern Andes of Colombia and the Andes of Venezuela. Plumage is mostly green with rusty-brown rump and tail. Its name is deceptive as the belly is typically brown or buff, not green. Similar to Rufous-tailed Hummingbird, but bill is darker and less red, and rump and tail are browner and less rufous. Inhabits forest edge, clearings, and plantations. Birds found in the Tepui region are now considered a separate species, Copper-tailed Hummingbird.
