The Scott's Oriole is almost completely confined to the Lower and Upper Sonoran Zones. This oriole breeds in the Lower Sonoran Zone from southern California, Nevada, Utah, western Colorado, central New Mexico and western Texas and south into Mexico, to Nuevo Leon, Vera Cruz, Puebla, and Lower California. Of these, Vera Cruz seems to be the least rich in Scott's Orioles, most likely due to its humid mountains. This bird's range is not changing at this point , however, with increasing climate change, the range will most likely move.
It winters in northwestern Mexico from Lower California, Sonora and Chihuahua, along the coast south to Oaxaca and in southern California. It is present year-round in the central and southern regions of Mexico. It is casually found throughout the western portion of the United States and also in Minnesota, Wisconsin, and Louisiana.
