Green-breasted Mountaingem

The green-breasted mountaingem is about 10 to 11 cm (3.9 to 4.3 in) long and weighs about 4 to 7 g (0.14 to 0.25 oz); males are larger than females. It has a medium-length straight black bill. Adults of both sexes have deep metallic grass green upperparts with some bronze on the rump and black uppertail coverts. They have a white stripe that curves down behind the eye and deep metallic grass green cheeks with a thin white stripe below them. Adult males' underparts are also mostly metallic grass green, with white or grayish white margins on the feathers. Voice: The green-breasted mountaingem's song is "a soft, scratchy warble...often with a trill at the end". Males usually sing from hidden perches, though sometimes in the open or in flight. Both sexes give "short, buzzy 'shrrrt' calls" while feeding.
