Green-throated Mountaingem

The green-throated mountaingem is 11 to 12 cm (4.3 to 4.7 in) long and weighs about 5.4 g (0.19 oz). Both sexes of all subspecies have a straight black bill, a white stripe behind the eye above a dark cheek, and a slightly forked tail. Adult males of the nominate subspecies have green upperparts with a bronzy rump and bluish black uppertail coverts. Their central tail feathers are black and the rest pale gray. Their throat is white with bluish green spots, their breast white, their belly grayish with green spots on the sides and flanks, and their undertail coverts dusky gray. Voice: What is thought to be the green-throated mountaingem's song is "a complex warble of squeaky notes and buzzy, gurgling trills, 'tsee-tsee-glr-tsee-glr-tsee-glugluglugluglu-glr-glr-tsee'." Its calls include "a hard, buzzy 'zzrrt', a short 'tsik' and high-pitched thin 'see'."
