Calliope Hummingbirds, Stellula calliope, are the smallest birds that breed regularly in North America. They breed and spend the summers in the western mountains from central British Columbia to Northern California and Utah and winter in Mexico. The adult male pictured here is readily identifiable by his streaked rose-magenta gorget and small size.
