The Timberline Sparrow (Spizella breweri taverneri) is a taxonomically controversial American sparrow. Usually treated as a subspecies of Brewer's Sparrow, it is still considered a distinct species Spizella taverneri by many authorities. While the Timberline Sparrow recognizably differs in some details, there is little reproductive isolation between the taxa.
When it was still considered a good species, it was listed as Least Concern by the IUCN[1].
