~~White-throated Mountaingem Hummingbird by Chris Jimenez Nature Photo~~
White-throated Mountain-gem - (Lampornis castaneoventris) is a hummingbird which breeds in the mountains of western Panama. It is replaced in southern Costa Rica by a distinct subspecies, the Gray-tailed Mountaingem, L. castaneoventris cinereicauda, which is very close to becoming a distinct species (García-Moreno et al., 2006). Another very close relative, the Purple-throated Mountaingem, is found sympatrically.
