==Behaviour==
 
==Behaviour==
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.
