Migrant: Calliope Hummingbird
Scientific Name: Selasphorus calliope
Conservation Status: Least Concern (Population stable)
The Calliope Hummingbirds travel around 5,000 miles each year in a big oval from the breeding to wintering grounds.
They migrate north along the Pacific Coast in the spring, but return to the wintering grounds in Mexico via an inland route along the Rocky Mountains.
They are the smallest long-distance migrant in the world.
