Anna’s Hummingbird is the most widespread hummingbird on North America’s Pacific slope. This adaptable bird species often lives in human habitats. During courtship, a male Anna’s Hummingbird stakes out territory over a flower patch with a rich nectar supply. A female Anna’s Hummingbird enters the male’s territory, mates and then leaves to build a nest. Unlike similar hummingbirds, Anna’s Hummingbird is not migratory.
