The Brewer’s Sparrow (Spizella breweri breweri) breeds in only fourteen confirmed sites in British Columbia. Breeding and non-breeding occurrences are restricted to the Southern Interior Ecoprovince. Most of the known breeding sites are restricted to four ecosections (Northern Okanogan Basin, Southern Okanogan Basin, Okanagan Range, and Thompson Basin). This subspecies’ prime breeding habitat occurs in sagebrush-grassland communities. Suitable habitat is limited and threatened. Conservation of this sparrow depends on maintaining large areas of moderately dense sagebrush for breeding habitat. No known breeding sites are formally protected. The Brewer’s Sparrow should be considered Threatened and at risk of becoming Endangered within the next five years. A re-evaluation of the subspecies should be done at that time.
