Editing Brewer's sparrow (section)

==Ecology and status==
These birds [[bird migration|migrate]] to the [[southwestern United States]] south to central [[Mexico]]. These birds forage primarily in shrubs or in low vegetation, but also on the ground. They mainly eat insects in summer with seeds becoming a more important part of the diet at other times of the year. They usually forage in flocks outside of the breeding season, sometimes with other sparrows. The female typically lays three to four eggs (up to five) in a [[cup nest]] in low shrubs.

Brewer's sparrow has decreased in some parts of its range. Causes are not well understood, but it is suspected that the decline is due at least in part to destruction of sagebrush habitat. Additional information on resource use and limitation during the wintering season is desperately needed. When the timberline sparrow was still considered a good species, Brewer's sparrow was classified as [[near threatened]] by the [[IUCN]]. However, as only entire species are evaluated for the [[IUCN Red List]], following the merger the entire population of ''S. breweri'' is classified as species of [[least concern]].<ref>[[BirdLife International]] (2008) [http://www.birdlife.org/datazone/species/index.html?action=SpcHTMDetails.asp&sid=32364&m=0 Brewer's Sparrow Species Factsheet], [http://www.birdlife.org/action/science/species/global_species_programme/whats_new.html 2008 IUCN Redlist status changes] {{webarchive |url=https://web.archive.org/web/20080914000000/http://www.birdlife.org/action/science/species/global_species_programme/whats_new.html |date=September 14, 2008 }}.</ref>
