Here’s a diagram, available on the Audubon site , that compares its 2000 range with its anticipated 2080 range: Only 1 percent of the bird’s breeding range remains stable between 2000 and 2080 if global warming continues on its current course. Chestnut-collared Longspur is one of those. Black Rosy-Finch. Brown-headed Nuthatch.
