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 species is the oriole found commonly in riparian areas (especially willows and cottonwoods) of the western U.S. It hybridizes with the Baltimore Oriole on the Great Plains, and the two were once considered the same species, “Northern Oriole.” The summer range is projected by Audubon’s climate model to be mostly stable and possibly increase, but much of the new climate space far from the rest of the species’ range—in the southeastern U.S.—seems unlikely to be colonized. The model’s winter projection for wintering birds in the United States shows only 5% stable by 2080, but most Bullock’s Orioles winter in central and southern Mexico, outside the range of the model.
