Cool Facts: The song is a series of two opening notes followed by a buzz or trill, or sometimes several. Black-throated Sparrows are often found in mixed flocks of White-crowned Sparrows and Brewer's Sparrows in the winter. The Black-throated Sparrow is the king of the desert-adapted sparrows as it can satisfy all its water requirements from the seeds and insects it eats. It will, however, take advantage of spring water if available.

The Black-throated Sparrow establishes a large territory it defends during nest construction and egg laying. Once incubation starts, males are less responsive to intruders and their territory boundary shrinks.
