AUDUBON • March 7, 2021
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. The results are clear: Birds will be forced to relocate to find favorable homes. And they may not survive.
