In the spring, Rufous Hummingbirds journey from Mexico to the northwest U.S., some as far north as Alaska! That’s almost 1,000 miles one way for a bird measuring just under four inches beak to tail, making this the longest migration of any bird relative to body length. Not long after arriving, they bulk up on nectar and bugs for the scenic return trip over the Rocky Mountains.
