Colorful Puffleg

The colorful puffleg is about 8 to 9 cm (3.1 to 3.5 in) long. It has a straight blackish bill. The male has dark shining green upperparts with a glittering green forehead. It has an iridescent green gorget and upper breast, a glittering indigo blue belly, and glittering red and copper undertail coverts. The tail is forked; it is dark bronzy green above and shining golden bronzy green below. The female has mostly white underparts with green dots on the sides of the throat and the breast and reddish bronze spots on the flanks and the sides of the belly. Voice: As of early 2022, Cornell University's Macaulay Library had no recordings of colorful puffleg vocalization, and Xeno-canto had only three. What is thought to be its song is "a repeated single metallic short note 'tsit'".
