Allen's hummingbird (Selasphorus sasin) is a species of hummingbird that breeds in the western United States. It is one of seven species in the genus Selasphorus. Allen's hummingbird is a small bird, with mature adults reaching only 3 to 3.5 in (76 to 89 mm) in length and weighing approximately 2 to 4 grams in weight. They are known for their vibrant colors and energetic behaviors, making them a popular subject for birdwatchers and nature enthusiasts. The male has a green back and forehead, with rust-colored (rufous) flanks, rump, and tail. The male's throat is an iridescent orange-red. The male hummingbirds make use of their elaborate colors to impress the females, which is crucial for mating season. The female and immature Allen's hummingbirds are similarly colored, but lack the iridescent throat patch, instead having a series of speckles on their throats. Females are mostly green, featuring rufous color only on the tail, which also has white tips. Immature Allen's hummingbirds are so similar to the female rufous hummingbird, the two are almost indistinguishable in the field.

Possible
About 30% of wildlife watchers report an Allen's Hummingbird sighting in Channel Islands National Park on a given day, based on 1,497 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 38th most-seen of the 276 birds we can rate there. Over three days the chance rises to about 60%, and over a week to about 90%, if each day is a fresh chance.

Those are among Channel Islands National Park's wettest months, with about 60 mm of rain a month against almost none in July.
Between 7 and 10 am
Across all the parks we cover, that three-hour window holds the most Allen's 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.

GBIF citizen-science records
It is estimated from how often the Allen's Hummingbird is recorded against all the birds logged in Channel Islands National Park (1,497 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.
