Found only in southwestern Mexico, Green-fronted Hummingbird inhabits arid scrub, pine oak forests, oak scrub, thorn forests, riparian woodlands, and partially open areas. Following the breeding season, some birds move to lower elevations. Year-round, Green-fronted Hummingbirds collect nectar from flowers at middle to upper levels and hawk for insects. Both males and females are all white below. Males have coppery tails that range from bronzy to more purplish while females tend to show less copper and more greenish gold in the tail.
