The Black-throated Sparrow is well adapted to its desert habitat. Studies have shown that this bird 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 water holes. After it rains, these sparrows gather into small flocks and feed on vegetation and insects, which provides all the moisture they need.
