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 Reserva de la Biosfera Mariposa Monarca on a given day, based on 12 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 86th most-seen of the 103 birds we can rate there. Over three days the chance rises to about 10%, and over a week to about 30%, if each day is a fresh chance.
January and February
In those months about 10% of wildlife watchers report a Broad-billed Hummingbird in Reserva de la Biosfera Mariposa Monarca on a given day, against under 5% in March, May and October–December, the lowest months. Those are among Reserva de la Biosfera Mariposa Monarca's driest months, with about 25 mm of rain a month against 270 mm in July. April and June–September have too few records to rate.
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.
3rd of 4
Of the 4 parks where we can rate Broad-billed Hummingbird sightings, Reserva de la Biosfera Mariposa Monarca ranks 3rd at under 5%. The best odds are in Cumbres de Monterrey National Park (Mexico, about 20%) and Saguaro National Park (United States, about 20%).
Same family: Trochilidae
The closest relatives of the Broad-billed Hummingbird that you can see in Reserva de la Biosfera Mariposa Monarca (family Trochilidae, Hummingbirds) are White-eared Hummingbird (about 80%), Mexican Violetear (about 50%) and Rivoli's Hummingbird (about 40%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Broad-billed Hummingbird is recorded against all the birds logged in Reserva de la Biosfera Mariposa Monarca (12 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.
