Black-throated Sparrow

Scientific name: Amphispiza bilineata

Like most songbirds, male Black-throated Sparrows establish territories on their breeding ground. In an interesting twist, these territories are largest during territory establishment and courtship, and shrink once incubation of the eggs begins. In wetter years, Black-throated Sparrows may raise two broods.

Suppression of natural wildfires allows vegetation to become too thick for Black-throated Sparrows. When a fire eventually does take place, this thick vegetation burns so hot and so completely that the shrubs are destroyed. These habitat changes present conservation challenges for this species.
