Range

Discussion

This handsome sparrow of the arid Southwest is well named. Its old name, "Desert Sparrow," is also apt, for despite its vivid markings, it is often difficult to detect among the rocks and scrub, especially when not moving about. However, it may be observed when it mounts a bush or rock to sing its pleasant song. The Black-throated Sparrow is well adapted to the extremes of its habitat. Studies have shown that it has a great tolerance for heat and drought. During the hot months of late summer and early fall it maintains itself on dry seeds and drinks regularly at water holes. After the rains, these sparrows scatter into small flocks and feed on vegetation and insects, from which they derive all the moisture they need. They raise their young in the dry upland desert.

Nesting

Four white eggs in a loosely built nest of bark strips, grass, and stems, lined with wool, hair, or feathers, and placed in a thorny bush.
