Sagebrush Sparrow
The sagebrush sparrow (''Artemisiospiza nevadensis'') is a medium-sized sparrow of the western United States and northwestern Mexico. It used to be placed in the genus ''Amphispiza'', but evidence from 2007 and 2009 suggested it be placed in its own genus.Klicka and Spellman, 2007; DaCosta et al., 2009 Habitat Sagebrush 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 species 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. The habitat of sagebrush sparrows is frequently threatened by bush encroachment or the invasion of herbaceous plants. Population Although sagebrush sparrow numbers are generally strong, significant declines in sagebrush habitat in the west could be expected to decrease popu ...

Bell's Sparrow
Bell's sparrow (''Artemisiospiza belli'') is a medium-sized sparrow of the western United States and northwestern Mexico. It used to be placed in the genus ''Amphispiza'', but recent evidence suggested it be placed in its own genus. Four populations are resident to the west: subspecies ''canescens'' breeds in south-central California, the dark nominate subspecies ''belli'' in the California Coast Ranges and part of the western slope of the Sierra Nevada south to about 29°N in Baja California, the equally dark subspecies ''clementeae'' limited to San Clemente Island, and subspecies ''cinerea'' in western Baja California from 29°N to 26°45′N. The AOU now considers Bell's sparrow a separate species, formerly grouped with the sagebrush sparrow, and together previously known as the sage sparrow. Characteristics Bell's sparrow is difficult to separate in the field from the sagebrush sparrow. Both species measure about long and weigh approximately . In general, with Bell's S ...
