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.
In summer, arid hillsides (especially those covered by scrubby oaks and mountain mahogany) in the interior West are home to this cheery species. Audubon's climate model projects an 86 percent loss of current summer range, with a diffusion northward towards potential new areas. Much of the “new” area is already currently occupied by the species, so perhaps the model’s estimates are a bit generous. The species currently winters in interior southern Mexico, and the model makes no predictions about the winter situation.
