The green-fronted hummingbird (Ramosomyia viridifrons) is a species of hummingbird in the "emeralds", tribe Trochilini of subfamily Trochilinae. It is found in Mexico and possibly Guatemala. The green-fronted hummingbird was formerly placed in the genus Amazilia. A molecular phylogenetic study published in 2014 found that Amazilia was polyphyletic. In the revised classification to create monophyletic genera, the green-fronted hummingbird was one of three species moved to the resurrected genus Leucolia by some taxonomic systems. However, a study published in 2021 showed that Leucolia was not available because of the principle of priority. The authors proposed the new genus Ramosomyia and in mid-2022 it was adopted by the North American Classification Committee of the American Ornithological Society (AOS) and the International Ornithological Committee (IOC). As of that date the Clements taxonomy retains the species in Leucolia and BirdLife International's Handbook of the Birds of the World (HBW) in the earlier Amazilia. Wikipedia →

With luck
About 10% of wildlife watchers report a Green-fronted Hummingbird sighting in Cañón del Sumidero National Park on a given day, based on 65 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 129th most-seen of the 243 birds we can rate there. Over three days the chance rises to about 20%, and over a week to about 40%, if each day is a fresh chance.
March–April, June–August and October–November
In those months about 10% of wildlife watchers report a Green-fronted Hummingbird in Cañón del Sumidero National Park on a given day, against under 5% in May, September and December–February, the lowest months.
Between 7 and 10 am
Across all the parks we cover, that three-hour window holds the most Green-fronted Hummingbird 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 Cañón del Sumidero National Park, in our data
Cañón del Sumidero National Park is the only park on Wallace's Line with enough records to rate Green-fronted Hummingbird sightings: about 10% of wildlife watchers there report one on a given day.
Same family: Trochilidae
The closest relatives of the Green-fronted Hummingbird that you can see in Cañón del Sumidero National Park (family Trochilidae, Hummingbirds) are Canivet's Emerald (about 40%), Berylline Hummingbird (about 30%) and Ruby-throated Hummingbird (about 20%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Green-fronted Hummingbird is recorded against all the birds logged in Cañón del Sumidero National Park (65 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.
