Mexican Violetear Colibri thalassinus

Rather large, overall bright green hummingbird of highlands. Favors pine-oak forest and edge, especially overgrown clearings and roadsides with dense flower banks. Fairly common and is especially conspicuous when singing. Song is a jerky, metallic, chipping song given tirelessly from an exposed twig at middle to upper levels in trees. When feeding often stays fairly well hidden within flowers. Note overall deep green plumage with dark violet cheek and breast patches, and broad dark tail band.
