Long-tailed Sylph

Um dos beija-flores mais vistosamente ornamentados, os machos do beija-flor-de-cauda-longa (Aglaiocercus kingii) possuem plumagem verde-iridescente e retrizes externas dramaticamente alongadas em forma de fita, atingindo até 22 cm — mais de três vezes o comprimento do corpo. Encontrado nas florestas nubladas andinas da Colômbia e Venezuela, habita florestas montanas úmidas entre 1.400 e 2.800 metros de altitude. Os machos realizam voos elaborados para atrair as fêmeas. Suas caudas extravagantes são um exemplo clássico de seleção sexual por preferência feminina.
