Lampornis

Mountaingems are a genus of hummingbirds, Lampornis, which inhabit mountainous regions from the south-western United States to the Isthmus of Panama.

These are medium-sized to large (10–13 cm) hummingbirds with shortish slightly curved black bills. The males typically have green upperparts and a brightly coloured throat, which is a dull colour in the female. The females of some species also may differ significantly from the males in other plumage features.
