Calliope Hummingbird


IUCN Conservation Status: Least Concern

The Calliope Hummingbird is the smallest bird in North America north of Mexico. Despite its small stature, it breeds in the chilly mountain environments of the northwestern United States. The male’s magenta burst of rays at its throat make it a standout from other hummingbirds. Tiny but tough, these birds are the smallest long-distance avian migrant in the world, spending winters in Mexico and a few small pockets of the southern U.S.
