Probably closely related to S. pusilla, with which it shares many similarities in song and habitat, and S. wortheni, to which it is very similar in general appearance; mitochondrial DNA indicates that present species and S. pusilla are sister-taxa (S. wortheni may be closer to S. breweri). Present species is the only member of genus that exhibits sexual plumage dimorphism. Race caurina often synonymized with cana. Four subspecies generally recognized.

Subspecies and Distribution
  • S. a. caurina A. H. Miller, 1929 – coast ranges of WC California from Contra Costa County S to San Benito County, occasionally N to S Oregon, in W USA; non-breeding range poorly known (one record from Santa Cruz I, in California).
  • S. a. cana Coues, 1866 – inner coastal mountains of C & SW California (from Monterey County S on W slopes of S Sierra Nevada) and extreme NW Mexico (N Baja California); non-breeding Baja California Sur.
  • S. a. evura Coues, 1866 – SE California, S Nevada, SW Utah, C & SE Arizona, C & S New Mexico, W Texas and extreme N Mexico (NE Sonora); non-breeding range poorly known.
  • S. a. atrogularis (Cabanis, 1851) – C plateau of Mexico from Durango, S Coahuila and W Nuevo León S to C Oaxaca.
