Closely related to S. chrysoparia, S. virens, S. townsendi and S. nigrescens; probably the sister-species of S. townsendi, and they have occasionally been considered conspecific. Hybridizes frequently with latter species (producing fertile young); has hybridized also with S. nigrescens. Monotypic.

Distribution:

W USA from coastal mountains of W Washington S to C & S California (including Sierra Nevada). Migrates to non-breeding grounds mainly from N Mexico S to N Nicaragua, casually S to Costa Rica and W Panama; also in smaller numbers to coastal S California.
