Black-thighed Puffleg

Um beija-flor puffleg andino que recebe seu nome pelas coxas pretas aveludadas dos machos, que contrastam com os característicos tufos brancos de penas nas patas, os puffleg-de-coxa-preta habitam florestas montanas úmidas e bordas de floresta no Equador e na Colômbia em altitudes de 1.500 a 3.500 metros. Os machos exibem plumagem verde brilhante com cauda violeta-azul. Classificado como Quase Ameaçado devido ao desmatamento da floresta nublada andina, com populações em declínio à medida que o habitat especializado de alta altitude é desmatado para uso agrícola.
