Anna's Hummingbirds in coastal California, Oregon, Washington, and Vancouver Island do not migrate at all, and a year-round feeder usually means year-round birds.

In Spring, the exciting annual North American hummingbird migration begins! These gorgeous birds travel from their winter homes in South or Central America and Mexico to the north.
