The species spends winters in southern Mexico, Central America (as far south as Costa Rica), and in the West Indies.

From March through May they migrate north, some through the eastern two thirds of Texas, some apparently through Cuba and Florida, and some apparently directly across the Gulf of Mexico.ufous Hummingbird Migration -- In spring Rufous Hummingbirds migrate up the Pacific coast, passing through California from February to May.
