Range and Habitat
Anna's Hummingbird: Resident from northern California southward; spends winters regularly from British Columbia south to Arizona. Preferred habitats include chaparral, brushy oak woodlands, and gardens.
The Anna's Hummingbird can primarily be found in the United States, Mexico and Canada. Despite the fact that it is native to only three countries, its range is massive, reaching nearly half a million square kilometers. The population of this bird species is at 1.5 million individual birds. The population of this bird at this time seems to be fairly stable and presents no immediate concerns for population decrease. As a result, Anna's Hummingbird has been downgraded from the Lower Risk rating which it was given in 1988 and currently has a Least Concern rating.
Anna's Hummingbirds consume more insects than any other North American hummingbird.
Increased planting of ornamental, flowering plants, due to development in California over the past fifty years, has allowed these birds to greatly expand their breeding range.
Their hearts beat at 1260 beats per minute.
A group of hummingbirds has many collective nouns, including a "bouquet", "glittering", " hover", "shimmer", and "tune" of hummingbirds.
