High Quality Content by WIKIPEDIA articles! The Sage Sparrow (Amphispiza belli) is a medium-sized sparrow of the western United States and northwestern Mexico. Sage Sparrows are indeed often tied to sagebrush habitats, although they can also be found in brushy stands of saltbush, chamise, and other low shrubs of the arid Interior West. The most widespread population (subspecies nevadensis) breeds in the interior of the Western United States (between the Rocky Mountains and the coastal ranges such as the Cascades). It winters in the Mexican-border states and northern Sonora and Chihuahua.
