The White-throated Mountain-gemLampornis castaneoventris, is a hummingbird which breeds in the mountains of western Panama. The shortish black bill is slightly curved. The adult male has bronze-green upperparts and underparts except for a brilliant green crown, white throat and blue tail. The female lacks the bright crown and throat, and has rich cinnamon underparts.
These were photographed at the Savegre Mountain Resort, Costa Rica.
