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.

GBIF citizen-science records
It is estimated from how often the Purple-throated Mountain-gem is recorded against all the birds logged in San José (17 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
