Metadata (Data about data or how the map was made)
This sparrow is common in shrub-steppe habitats in higher areas of the Columbia Basin and Okanogan valley. It is less common in the Methow valley, but local and uncommon in the hottests parts of the southern Columbia Basin. It is most abundant in tracts of sage brush. A small population still exists in Asotin County in remnant patches. This sparrow is a local and rare breeder elsewhere in isolated grassland habitats, such as in the Spokane valley (Spokane County) and Little Pend Oreille National Wildlife Refuge (Stevens County).
The core of this species is in steppe zones, within its current known breeding range. Grasslands shrub savanna, shrublands, and tree savanna were good habitats; not modeled in the Spokane valley or in Stevens County. Preference is given to patches with taller and denser shrubs where nests are placed in the shrub canopy. An experiment involving burned patches of sagebrush with complete shrub loss showed a dramatic decrease in Brewer's Sparrow numbers in the following two years, followed by an increase in the third year, when numbers were higher than in adjacent unburned patches.
