Breeding Range Map
The green area shows the predicted habitats for breeding only. The habitats were identified using 1991 satellite imagery, Breeding Bird Atlas (BBA), other datasets and experts throughout the state, as part of the Washington Gap Analysis Project. Habitats used during non-breeding months and migratory rest-stops were not mapped.

The Lark Sparrow is uncommon in shrubby or grassy habitats of eastern Washington below the lower treeline. Preferred habitat is shrub savanna, where shrubs are present but scarce, and grasses dominate, especially Cheatgrass (Bromus tectorum). The presence of basalt may also be important. In northeastern Washington, it is found in agricultural areas of the Ponderosa Pine zone.

Steppe, Ponderosa Pine, and Oak zones were core. Bare ground, sparse vegetation, grassland, shrub savanna, shrublands, and tree savanna were good habitats in all zones. Agricultural fields (except orchards) were good habitats in the Oak and Ponderosa Pine. Though widespread, this species is uncommon throughout its range.zones.

Washington breeders represent the western subspecies C. g. strigatus.
