Fairly large hummingbird of brushy woodland, edge and semiopen areas with flowering trees, mainly in drier habitats in southwestern Mexico and neighboring Guatemala. Feeds mainly at middle to upper levels in trees. Combination of bright white underparts (throat sometimes stained yellow by pollen) and bright red bill with black tip are distinctive. Male and female similar, but male has a more coppery, less greenish tail. The crown is deep green, unlike similar Violet-crowned Hummingbird, which occurs to the north of Green-fronted.
