Spends most of its time on the ground, running or hopping through grass, but isn't as reclusive as some sparrows. Males sing from elevated perches. Found in mixed-sparrow flocks with Savannah Sparrows, Grasshopper Sparrows, Brewer's Sparrows, and Lark Buntings outside of the breeding season.
- Habitat
Found in open grassy areas including prairie, weedy fields, sagebrush steppe, meadows, pastures, and roadsides. Tends to avoid areas with taller grass and wetter areas.
