The Black-throated Sparrow, Amphispiza bilineata, is a small sparrow of the bird family Emberizidae. It is found in arid desert scrub in the southwestern United States. It is sometimes referred to as the Desert Sparrow because of its preferred habitat.
This bird reaches a length of about 4.5 to 5.5 inches, and is pale gray above, with a distinctive black and white head pattern. Its call is high and bell-like, and its song is a fairly simple mechanical tinkling. Its diet consists mainly of insects and seeds. They travel in small groups, though larger groups may accumulate around sources of desert water.
