Black-throated sparrow
The black-throated sparrow (Amphispiza bilineata) is a small New World sparrow primarily found in the southwestern United States and Mexico. It is the only member of the genus Amphispiza; the five-striped sparrow, formerly also classified in Amphispiza, is now thought to be in the monotypic genus Amphispizopsis. It is sometimes referred to as the desert sparrow, due to its preferred habitat of arid desert hillsides and scrub. This name usually refers to the desert sparrow of Africa and Asia. Description

The black-throated sparrow is pale gray above, with a distinctive black and white head pattern. Immature birds are similar but lack a black throat. Its call is high and bell-like, and its song is a fairly simple, mechanical tinkling. It feeds primarily on insects and seeds, and travels in small groups, though larger groups may accumulate around sources of water in the desert. It has a loose nest of grass twigs and plant fibers carefully hidden in brush  above the ground. Three or four white or pale blue eggs are laid. References
