Survival by Degrees: 389 Species on the Brink

Two-thirds of North American birds are at risk of extinction from global temperature rise and what you can do to help.

As the climate changes, so will the places birds need.

Audubon scientists took advantage of 140 million observations, recorded by birders and scientists, to describe where 604 North American bird species live today—an area known as their “range.” They then used the latest climate models to project how each species’s range will shift as climate change and other human impacts advance across the continent. See how climate change will impact California's birds.

The results are clear: Birds will be forced to relocate to find favorable homes. And they may not survive. 

Climate change is a serious threat to California birds. Highly and moderately vulnerable birds may lose more than half of their current range—the geographic area where they live—as they are forced to search for suitable habitat and climate conditions elsewhere. The birds that nest or spend the winter in your area are most vulnerable across their entire range. Some birds may lose range outside of your state, making the protection of their current habitat in your area even more important. 

Highly vulnerable birds include iconic California birds such as the California Quail, Allen’s Hummingbird, Nuttall's Woodpecker, Yellow-billed Magpie, Sharp-shinned Hawk, Cassin's Kingbird, Bushtit, Acorn Woodpecker, and many others. These are birds that all of us know well from our backyards and from our own experiences in California’s beautiful outdoors. 

Audubon California is addressing this challenge by protecting the habitats that we know birds will need now and into the future, and doing what we can to lessen the severity of global warming. We’ll do this work with a variety of partners on the ground and in the halls of the State Capitol and Washington, D.C. But we won’t be able to rise to this challenge without the involvement of California residents who care about birds. We need people not only to join us in this important work, but to also raise their voices to call for meaningful policy and legislative action on climate. TAKE ACTION>>
