Where you might see them
Rufous Hummingbirds breed further north than any other hummingbirds. Their location in the US varies by season. They can be found in California during the spring, the Pacific Northwest and Alaska in the summer, and the Rocky Mountains in the fall.
Rufous Hummingbirds are feisty. They will attack other hummingbirds, including those large then them, at flowers and feeders.
