Since the 1970s, ornamental plants in residential areas along the Pacific coast and inland deserts provided expanded nectar and nesting sites, allowing the species to expand its breeding range to northern coastal regions without migrating. Year-round residence of Anna's hummingbirds in the Pacific Northwest is an example of ecological release dependent on acclimation to colder winter temperatures, introduced plants, and human provision of nectar feeders during winter.
These birds feed on nectar from flowers using a long extendable tongue. They also consume small insects and other arthropods caught in flight or gleaned from vegetation. Anna's hummingbird was formally described and illustrated in 1829 by the French naturalist René Lesson in his Histoire naturelle des Oiseaux-Mouches from a specimen that... Wikipedia →

Likely
About 40% of wildlife watchers report an Anna's Hummingbird sighting in Joshua Tree National Park on a given day, based on 1,107 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 16th most-seen of the 141 birds we can rate there. Over three days the chance rises to about 70%, and over a week to over 90%, if each day is a fresh chance.
September
In that month about 60% of wildlife watchers report an Anna's Hummingbird in Joshua Tree National Park on a given day, against about 20% in June and July, the lowest months.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Anna's 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.
Among the best
Of the 15 parks where we can rate Anna's Hummingbird sightings, Joshua Tree National Park ranks 3rd at about 40%, level with the leaders once rounded. The best odds are in Channel Islands National Park (United States, about 40%) and Sequoia and Kings Canyon National Parks (United States, about 40%). All parks ranked.
GBIF citizen-science records
It is estimated from how often the Anna's Hummingbird is recorded against all the birds logged in Joshua Tree National Park (1,107 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.
