Black-throated Sparrows (Passeriformes: Emberizidae: Amphispiza bilineata) are relatively easy to identify thanks to their bold facial markings and, unsurprisingly, black throats. These small birds inhabit desert scrublands of the western US and Mexico. They have a high tolerance for heat and can go for some time without drinking water. During dry periods they can get the water they need from the insects and seeds they eat.
These birds begin mating in February and nest throughout the spring and summer, raising two broods per year. After building nests low to the ground in shrubs and cacti, the females typically lay three or four eggs per brood. Adults spend a great deal of nesting season scouring the ground for insects to feed themselves and their chicks.
