The red-billed emerald (Chlorostilbon gibsoni) is a species of hummingbird in the "emeralds", tribe Trochilini of subfamily Trochilinae. It is found in Colombia and Venezuela. The red-billed emerald was originally described as a species and later treated as a subspecies of the blue-tailed emerald (Chlorostilbon mellisugus). Since the early 2000s, most taxonomist have again treated it as a species in its own right. It has also at times been considered conspecific with the western emerald (C. melanorhynchus).
The red-billed emerald is 7.6 to 9 cm (3.0 to 3.5 in) long and weighs about 2.8 g (0.099 oz). The males of all three subspecies have a straight bill with a mostly red mandible. The females' mandibles are red at the base. The bills are about 1.3 cm (0.51 in) long. Males of the nominate subspecies have dark bronze-green upperparts and a deeply forked blue-black tail. Their faces and underparts are glittering green to golden green. Nominate females are shining green above and plain gray below with... Wikipedia →

Rare
Under 5% of wildlife watchers report a Red-billed Emerald sighting in Tayrona National Natural Park on a given day, based on 38 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 161st most-seen of the 285 birds we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
March and October
In those months about 10% of wildlife watchers report a Red-billed Emerald in Tayrona National Natural Park on a given day, against under 5% in April–September and November–February, the lowest months.
Between 7 and 10 am
Across all the parks we cover, that three-hour window holds the most Red-billed Emerald 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 2 parks where we can rate Red-billed Emerald sightings, Tayrona National Natural Park has the highest daily chance: under 5%. Next come Los Nevados National Natural Park (Colombia, under 5%).
GBIF citizen-science records
It is estimated from how often the Red-billed Emerald is recorded against all the birds logged in Tayrona National Natural Park (38 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.
