Black-thighed Puffleg

An Andean puffleg hummingbird named for the males' distinctive velvety black thighs contrasting with the characteristic white leg feather puffs, black-thighed pufflegs inhabit humid montane forest and forest edges in Ecuador and Colombia at elevations of 1,500–3,500 meters. Males display glittering green plumage with a violet-blue tail. Listed as Near Threatened due to deforestation of the Andean cloud forest, with populations declining as the specialized high-altitude forest habitat is cleared for agriculture.
