The Allen's Hummingbird is a bird that Californians know and love. It appears at their backyard feeders, and throughout our open landscapes. It is a western bird, enjoying more than half of its breeding range in California. Audubon research projects that it will lose as much as 90% of its climate suitable breeding range in North America. In California, this is projected to mean a loss of more than 60% of its climate suitability range in California.

The map below illustrates the changes in breeding season climate suitability in California for the Allen's Hummingbird both now, and projected in 2050:
