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. Farther inland, Anna's may move seasonally to make best use of local resources; these movements may be more attuned to elevation than to latitude.
