Cassin’s Sparrow

Peucaea cassinii

The Cassin’s Sparrow is a year-round resident in southeastern Arizona, southern New Mexico, most of western and central Texas, and much of northern Mexico. In spring and summer some will migrate north into eastern Colorado, and western Kansas and Nebraska. They prefer arid brushy grasslands. In the breeding season, the males perform an aerial display called “Skylarking”, where they fly to great heights and float down on stiffened wings, singing the all the while.

The population of these birds varies widely in some regions from year to year. The absence or abundance of rainfall is believed to affect the seasonal population.
