Rufous Hummingbirds live in the western half of North America. They are long-distance migrants, with some individuals breeding in Alaska and spending the winter down in Mexico. Considering the small size of these birds, this is one of the longest migratory journeys of any bird in the world. Rufous Hummingbirds are known to have excellent memories, especially for location. Birds may return to the same backyard year after year, pinpointing the exact location of a previously known nectar feeder.
