The purple-throated mountaingem (Lampornis calolaemus) is a species of hummingbird in tribe Lampornithini of subfamily Trochilinae. It is found in Costa Rica, Nicaragua, and Panama.

The purple-throated mountaingem is 10 to 11.5 cm (3.9 to 4.5 in) long and weighs 4.5 to 6 g (0.16 to 0.21 oz). Both sexes of all subspecies have a medium-length straight black bill, a white to pale buff stripe behind the eye, and a fairly long tail.
Adult males of the nominate subspecies L. c. calolaemus have a glittering emerald green to bluish green forehead and... Wikipedia →
