Feeding

Black-throated sparrows eat seeds in the winter and insects in the breeding season. They eat a lot of bugs, but also grasses and herbs. To help digestion, some people take gravel. This bird is usually seen scavenging for insects on the ground.

Habitat

The black-throated sparrow prefers a desolate, sparse landscape. Habitats include creosote bushes and scrub in hot, dry desert uplands. These sparrows prefer steeply sloping or flat terrain. They prefer alluvial fans and hill slopes with exposed rock and gravel pavement.

Behavior

Black-throated sparrows migrate. During the winter, they remain in the southern breeding range. In the winter, they are often seen with white-crowned and Brewer’s sparrows. During some seasons, this species lacks access to water. It gets water from insects and seeds it eats. This adaptation, along with its high heat tolerance, makes it the ideal desert sparrow. Except in the summer when they mate, they are flocking birds.
