ID tip
The black-thighed puffleg is about 10 cm (3.9 in) long. It has a straight blackish bill. Males are mostly shining golden green overall, sometimes with black highlights, and has glittering malachite green upper- and undertail coverts. Their leg puffs are black and the tail is forked and black. Females are similar but have white underparts with green spots, and their leg puffs are a mix of black and grayish white. The female also has a blue tinge to the forehead. Juveniles resemble females. Voice: The black-thighed puffleg's only described vocalization is "a short buzzy trill 'tzzrr', repeated at irregular intervals". It is given both from a perch and while hovering, and is very different than the sounds of other Eriocnemis pufflegs.
