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 “sagebrush sea” seems so dull from the interstate or from 35,000 feet. Yet it is one of the most exquisitely adapted habitats in the U.S. Several bird species are more or less restricted to sagebrush during the breeding season, this one foremost among them. Sagebrush—a complex of plant species, actually—is already at risk from fire, overgrazing, and biological invasion. Climate change is expected to put further stress on the system. Unfortunately, but not surprisingly, Audubon's climate model forecasts major losses of suitable climate space during the Sage Thrasher’s summer season. Substantial gains in winter—at which time this thrasher is more of a generalist—may be expected.
