The black-chinned hummingbird (Archilochus alexandri) is a hummingbird occupying a broad range of habitats from deserts to mountain forests and urban areas in the western United States, southern British Columbia, and Mexico. It is migratory, wintering as far south as Mexico. In sunlight, an iridescent purple gorget forming a ring below the black chin feathers is a male characteristic. When in flight and hovering, its wings make a low-pitched humming sound.
The hybrid between the black-chinned hummingbird and Anna's hummingbird is called "Trochilus" violajugulum. The black-chinned hummingbird is also known to hybridize with Anna's, Lucifer, broad-tailed, and Costa's hummingbirds.
The black-chinned hummingbird is 8.25 cm (3.25 in) long. Adults are metallic green above and white-gray below with green flanks. Their bill is long, straight and slender. The adult male has a black face and chin, a glossy purple gorget (when accurately exposed to sunlight) and a dark forked tail. The female has a dark rounded tail with white tips and no throat patch. Juvenile plumage is similar to that of adult females, but with buff margins on the dorsal feathers. Juvenile... Wikipedia →

Rare
Under 5% of wildlife watchers report a Black-chinned Hummingbird sighting in Rocky Mountain National Park on a given day, based on 106 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 122nd most-seen of the 223 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.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Black-chinned Hummingbird in Rocky Mountain National Park on a given day, so our monthly data shows no clear season.
Between 6 and 9 am
Across all the parks we cover, that three-hour window holds the most Black-chinned Hummingbird sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
10th of 13
Of the 13 parks where we can rate Black-chinned Hummingbird sightings, Rocky Mountain National Park ranks 10th at under 5%. The best odds are in Zion National Park (United States, about 20%), Grand Canyon National Park (United States, about 10%) and Big Bend National Park (United States, about 10%).
Same family: Trochilidae
The closest relatives of the Black-chinned Hummingbird that you can see in Rocky Mountain National Park (family Trochilidae, Hummingbirds) are Broad-tailed Hummingbird (about 50%) and Rufous Hummingbird (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Black-chinned Hummingbird is recorded against all the birds logged in Rocky Mountain National Park (106 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.
