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.
The lack of a notch in the second rectrix is considered an important field mark to distinguish... Wikipedia →

GBIF citizen-science records
It is estimated from how often the Allen's Hummingbird is recorded against all the birds logged in Los Angeles (77,258 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.
