Green-fronted Hummingbird

About the Green-fronted Hummingbird

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.

The IOC and HBW assign two subspecies to the green-fronted hummingbird, the nominate R. v. viridifrons and R. v. villadai. AOS and Clements... Wikipedia →
