The black-throated sparrow is a small American sparrow primarily found in the southwestern United States and Mexico. 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. It has a loose nest of grass twigs and plant fibers carefully hidden in brush 6 to 18 inches above the ground. Three or four white or pale blue eggs are laid. It mostly eats seeds and insects. In general, probably eats more seeds in winter, more insects in summer. Also feeds on fresh green shoots, other green vegetation, and ripe berries and fruits when available.
