Purple-Throated Mountain-Gem, Costa Rica

The purple-throated mountaingem (Lampornis calolaemus) is a hummingbird which breeds in the mountains of southern Nicaragua, northern Costa Rica and western Panama. This bird inhabits forested areas in hilly terrain, and is found at altitudes from 800 to 2,500 m (2,600 to 8,200 ft).

It is replaced in southern Costa Rica by its close relatives, the white-throated and gray-tailed mountaingems, with which it is sometimes considered conspecific. These three species form a closely related group that evolved some 3.5 million years ago and has diversified since.
