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. The purple-throated mountaingem's taxonomy is somewhat unsettled.

Others have kept the purple-throated separate but lumped the other two as a single species. These three species form a closely related group that evolved some 3.5 million years ago and has diversified since.
The purple-throated mountaingem is 10 to 11.5 cm (3.9 to 4.5 in) long and weighs 4.5 to 6 g (0.16 to 0.21 oz). Both sexes of all subspecies have a medium-length straight black bill, a white to pale buff stripe behind the eye, and a fairly long tail.
Adult males of the nominate subspecies L. c. calolaemus have a glittering emerald green to bluish green forehead and... Wikipedia →

Likely
About 50% of wildlife watchers report a Purple-throated Mountain-gem sighting in Monteverde Cloud Forest Reserve on a given day, based on 8,369 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 6th most-seen of the 412 birds we can rate there. Over three days the chance rises to about 90%, and over a week to over 90%, if each day is a fresh chance.
April–July and December–February
In those months about 60% of wildlife watchers report a Purple-throated Mountain-gem in Monteverde Cloud Forest Reserve on a given day, against about 40% in September and October, the lowest months.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most Purple-throated Mountain-gem sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Yes
Of the 11 parks where we can rate Purple-throated Mountain-gem sightings, Monteverde Cloud Forest Reserve has the highest daily chance: about 50%. Next come Poás Volcano National Park (Costa Rica, about 20%) and Braulio Carrillo National Park (Costa Rica, about 20%).
GBIF citizen-science records
It is estimated from how often the Purple-throated Mountain-gem is recorded against all the birds logged in Monteverde Cloud Forest Reserve (8,369 verified sightings from 2019 to 2026), 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.
