The green-breasted mountaingem or green-breasted mountain-gem (Lampornis sybillae) is a species of hummingbird in tribe Lampornithini of subfamily Trochilinae. It is found in Honduras and Nicaragua. The green-breasted mountaingem has sometimes been considered conspecific with its close relative the green-throated mountaingem (Lampornis viridipallens) or may form a superspecies with it. It is monotypic.
The green-breasted mountaingem is about 10 to 11 cm (3.9 to 4.3 in) long and weighs about 4 to 7 g (0.14 to 0.25 oz); males are larger than females. It has a medium-length straight black bill. Adults of both sexes have deep metallic grass green upperparts with some bronze on the rump and black uppertail coverts. They have a white stripe that curves down behind the eye and deep metallic grass green cheeks with a thin white stripe below them.
Adult males' underparts are also mostly metallic grass green, with white or grayish white margins on the feathers. Their lower belly, vent area, and leg tufts are white. Their inner undertail coverts are green with white edges and the outer ones dusky gray with wide white edges. Their central tail feathers... Wikipedia →

Possible
About 30% of wildlife watchers report a Green-breasted Mountain-gem sighting in La Tigra National Park on a given day, based on 122 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 20th most-seen of the 176 birds we can rate there. Over three days the chance rises to about 60%, and over a week to about 90%, if each day is a fresh chance.
February
In that month about 60% of wildlife watchers report a Green-breasted Mountain-gem in La Tigra National Park on a given day, against about 10% in March and June–September, the lowest months. That is one of La Tigra National Park's driest months, with about 25 mm of rain against 260 mm in June.
Between 7 and 10 am
Across all the parks we cover, that three-hour window holds the most Green-breasted Mountain-gem sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Only La Tigra National Park, in our data
La Tigra National Park is the only park on Wallace's Line with enough records to rate Green-breasted Mountain-gem sightings: about 30% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Green-breasted Mountain-gem is recorded against all the birds logged in La Tigra National Park (122 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.
