The darker the color, the more favorable the climate conditions are for survival. The outlined areas represent approximate current range for each season. More on reading these maps.
The Gray-crowned Rosy-Finch is a variable species that breeds in varied (but always open and treeless) habitats. Some highly migratory populations nest on alpine tundra, while other resident populations nest on rocky shorelines on islands in the Bering Sea. Audubon's climate model projects a substantial decline of 69% in suitable climate space for wintering and a major shift in current range; only 13% of it is stable. Because of its relatively inaccessible breeding range and the scarcity of summer data, the model makes no projections for that season; but as with other mountaintop birds, there is reason for concern as the climate warms.
