The broad-billed hummingbird (Cynanthus latirostris) is a small hummingbird that resides in Mexico and the southwestern United States. Males and females have different features (see sexual dimorphism). The juveniles resemble the female adult more than the male adult. The broad-billed hummingbird is a bright green bird. The broad, red bill in both sexes and the male's blue gorget are useful for identification. The bird is also known for its other common names – the Colibrí Pico Ancho in Spanish and Colibri circé in French. It is more active during the day and less active during the night (see diurnality).
There are around 360 described species of hummingbirds that can be further categorized into nine different clades. The Cynanthus genus falls under the emerald clade of hummingbirds. The emerald clade formed between 10 and 15 million years ago and has the largest diversity of species. The broad-billed hummingbird was formally described in 1827 by William Swainson based on specimens collected by William Bullock in México. Swainson coined the binomial name Cynanthus latirostris. Swainson specified the type locality as "Table land ?" where he included a question mark. This... Wikipedia →

Rare
Under 5% of wildlife watchers report a Broad-billed Hummingbird sighting in El Vizcaíno Biosphere Reserve on a given day, based on 13 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 202nd most-seen of the 237 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.
October
In that month about 10% of wildlife watchers report a Broad-billed Hummingbird in El Vizcaíno Biosphere Reserve on a given day, against under 5% in November to September, the lowest months.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Broad-billed 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 parks where we can rate Broad-billed Hummingbird sightings, El Vizcaíno Biosphere Reserve ranks 4th at under 5%. The best odds are in Cumbres de Monterrey National Park (Mexico, about 20%), Saguaro National Park (United States, about 20%) and Reserva de la Biosfera Mariposa Monarca (Mexico, under 5%).

GBIF citizen-science records
It is estimated from how often the Broad-billed Hummingbird is recorded against all the birds logged in El Vizcaíno Biosphere Reserve (13 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.
