Tiny hummingbird with a white rump band and rusty tail. Adult male is stunning, with a flowing, glittering green beard ending in white spots, an iridescent green face, and a small crest. Female and young male are much plainer than male, but they typically have a white throat with dark patch in the middle, and lack the buffy or rusty tones on the underparts shown by females of several similar species. Distinguished from female Peacock Coquette by lack of streaking on the throat. Inhabits humid lowland and foothill forest and is quite scarce in most of its range. It was previously considered to be a subspecies of Festive Coquette.
