Anna's Hummingbirds: Characteristics, Habitat, Metabolism, Mating, Reproduction, Nesting, Chicks

Anna's hummingbirds are some of the most amazing hummingbirds. They live in North America and do not migrate south for the winter. They breed not only in sunny California and warm Arizona but also in Washington state and Vancouver, Canada. And they visit Alaska for the winter. Anna's hummingbirds seem like flying jewels of iridescent reddish-pink crown and throat in the male and throat in the female. The male is the only North American hummingbird with a radiant reddish-pink crown. The female is distinguished from other female hummingbirds in North America by the purplish-pink color on the throat, though this is not always the case with Anna's females. Hummingbirds have unique metabolism and bone and muscle structures. They have a fantastic wing beat rate, heart rate, respiration rate, and resting metabolic rate. Anna's male breaks the record for fastest bird relative to size. Enjoy this video while you learn about Anna's hummingbirds: colors, size, song and calls, diet, metabolism, courtship, and nesting.
