The violet-crowned hummingbird (Ramosomyia violiceps) is a hummingbird in the "emeralds", tribe Trochilini of subfamily Trochilinae. It is found in Mexico and the southwestern United States. The violet-crowned 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 violet-crowned 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 and the International Ornithological Committee. As of that date the Clements taxonomy retains the species in Leucolia and BirdLife International's Handbook of the Birds of the World in the earlier Amazilia.

Rare
Under 5% of wildlife watchers report a Violet-crowned Hummingbird sighting in Mexico City on a given day, based on 179 verified sightings from GBIF citizen-science data. It is the 186th most-seen of the 332 birds we can rate there. Over three days the chance rises to under 5%, and over a week to about 10%, if each day is a fresh chance.
May and June
In those months about 10% of wildlife watchers report a Violet-crowned Hummingbird in Mexico City on a given day, against under 5% in July to April, the lowest months. Those are among Mexico City's wettest months, with about 95 mm of rain a month against 5 mm in December.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Violet-crowned 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.
4th of 4
Of the 4 cities where we can rate Violet-crowned Hummingbird sightings, Mexico City ranks 4th at under 5%. The best odds are in Guadalajara (México, about 60%), Puebla (México, about 40%) and León (México, about 40%).
Same family: Trochilidae
The closest relatives of the Violet-crowned Hummingbird that you can see in Mexico City (family Trochilidae, Hummingbirds) are Berylline Hummingbird (about 60%), Broad-billed Hummingbird (about 50%) and White-eared Hummingbird (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Violet-crowned Hummingbird is recorded against all the birds logged in Mexico City (179 verified sightings), 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.
