A male Anna's Hummingbird photographed in our backyard. My Flickr friend Keith from Hull, England called them little flying jewels which is a very apt description. This hummer is the partner of the female in my previous photo.
Calypte anna
Anna's hummingbirds are found along the western coast of North America, from southern Canada to northern Baja California, and inland to southern and central Arizona, extreme southern Nevada and southeastern Utah, and western Texas. They tend to be permanent residents within their range, and are very territorial. However, birds have been spotted far outside their range in such places as southern Alaska, Saskatchewan, New York, Florida, Louisiana, and Newfoundland.
While the species was originally restricted to the chaparral of California and Baja California, their range expanded north to Oregon, Washington, and British Columbia, and east to Arizona in the 1960s and 70s. This rapid expansion can be attributed to the widespread planting of non-native species, such as eucalyptus, as well as the use of bird feeders, in combination with the species' natural tendency for extensive postbreeding dispersal.
Anna's hummingbirds have the northernmost year-round range of any hummingbird. During cold temperatures, Anna's hummingbirds gradually gain weight during the day as they convert sugar to fat. In addition, hummingbirds with inadequate stores of body fat or insufficient plumage are able to survive periods of subfreezing weather by lowering their metabolic rate and entering a state of torpor.
The population of Anna's hummingbirds is an estimated 1.5 million, which appears to be stable, and they are not considered an endangered species. In 2017, Anna's hummingbird was named the official bird of the city of Vancouver, British Columbia, Canada where it resides year round through winter.
