- Source: Timberline sparrow
The timberline sparrow (Spizella breweri taverneri) is a taxonomically controversial American sparrow. Usually treated as a subspecies of Brewer's sparrow, it is considered a distinct species Spizella taverneri by some authorities. While the timberline sparrow recognizably differs in some details, there is little reproductive isolation between the taxa.
When it was still considered a species, it was listed as being of least concern by the IUCN.
