Distribution of the White-throated Mountain-gem
eBird range map for White-throated Mountain-gem

Generated from eBird observations (Year-Round, 1900-present)

Distribution in the Americas

White-throated Mountain-gem occurs from southern Costa Rica (Cordillera Talamanca) to western Panama (western Chiriquí), from 1500 m to timberline (Ridgely and Gwynne 1989, Stiles and Skutch 1989, Angehr and Dean 2010, Garrigues and Dean 2014, eBird 2016).

White-throated Mountain-gem is considered to be resident, but, at least in Costa Rica, it descends a few hundred m after breeding (Stiles and Skutch 1989).

Distribution outside the Americas

White-throated Mountain-gem is endemic to southern Central America.


Found in oak forest, borders, and shrub clearing in highlands of western Chiriquí and Talamanca Cordillera (Ridgely & Gwynne 1989, Stiles & Skutch 1989, Garrigues & Dean 2014). This species is also observed in gardens, at small human settlements, near or right at the edge of the forest.

Historical changes

Although none have been reported, the range might have contracted somewhat due to deforestation of the pristine forests of the highlands for the advance of the agricultural frontier and coffee plantations.

Fossil history

None reported.
