Probably closest to S. fulvescens, and perhaps also close to S. occidentalis. Has at times been considered conspecific with S. fulvescens, but bigger than nearby populations of latter and with different vocalizations. Occasionally hybridizes with S. occidentalis#R#R. In recent study of species’ genetic structure#R, Mexican sartorii found to be separated from remaining taxa of present species by S. fulvescens, suggesting that it is a species-level taxon; has therefore been elevated to species rank by some, this treatment supported by vocal differences#R, although further evidence desirable; may be closer to S. fulvescens than to other taxa currently included within S. varia#R. Races georgica and helveola sometimes synonymized with nominate#R. Four subspecies currently recognized.
