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.
This classic “LBJ,” or “little brown job,” is one of the world’s most accomplished migrants. The Gray-cheeked Thrush winters in Amazonia, and many breeders penetrate well into the Russian Far East. The Audubon climate model’s focus is on the North American nesting population, showing a general shift northward of the species’ already far-northern breeding range. Areas of suitable climate for this thrush are projected to decline by about 30 percent in Canada and Alaska, as available land area is simply pushed right to the shores of the Arctic Ocean. Additionally of concern, only 33% of the current range is predicted to be climate stable. Of interest is the possibility that this diminutive but powerful flier may be able to infiltrate new areas of suitable habitat in Greenland and Russia.
