About the White-bellied Mountain-gem

The white-bellied mountaingem or white-bellied mountain-gem (Lampornis hemileucus) is a species of hummingbird in tribe Lampornithini of subfamily Trochilinae. It is found in Costa Rica and Panama. The white-bellied mountaingem is monotypic. There is some evidence that it does not belong in genus Lampornis.

The white-bellied mountaingem is 10 to 11 cm (3.9 to 4.3 in) long. Males weigh about 6.2 g (0.22 oz) and females 5.1 g (0.18 oz). Both sexes have a medium-length black bill, a long white stripe behind the eye, and pinkish feet. Adult males' face and crown are glittering green, much of the rest of the upperparts bronzy green, and the uppertail coverts bronzy. The tail is also bronzy, with dusky gray bands near the end of the outer feathers. The gorget is blue-violet and the rest of the underparts white with green speckles along the sides. Adult females are similar, but the face and crown are less glittering and the throat is white with green speckles. Juveniles of both sexes have rusty fringes on the green feathers; males have a dull bronze gorget.
