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.
Although not currently the focus of intensive management, the Gray Vireo is uncommon and local throughout its limited breeding range in the Four Corners region of the U.S. It breeds only in pinyon-juniper environments in arid and rocky foothills, and it is eagerly sought by birdwatchers. Audubon’s climate model projects an almost complete shift in climate space for this habitat specialist, with only 3% of the current range remaining suitable by 2080, even though the climate space may increase greatly. It is an open question if this species would be able to take advantage of the new, and far-flung, summer regions.
