Perhaps most closely related to Z. atricapilla, with which it hybridizes; hybrids with Z. albicollis and Melospiza melodia also recorded. Coastal races pugetensis and nuttalli are somewhat divergent morphologically, vocally, in breeding habitat, and in migration distance; however, song of race oriantha is rather close to these two, and deeper analysis of characters separating or uniting these taxa is needed. In Canada, race gambelii intergrades with oriantha in SE British Columbia and with nominate in N Manitoba. Proposed race aphaea (described from Idaho, presumably on migration) included in nominate. Five subspecies currently recognized.

Subspecies and Distribution
  • Z. l. gambelii (Nuttall, 1840) – Alaska and W Canada (E to Nunavut and N Manitoba, S to S British Columbia, SW Alberta and N Saskatchewan; non-breeding quarters in S British Columbia and W USA (E to NE Kansas, S to California) and Mexico (S to Nayarit, Aguascalientes and San Luis Potosí).
  • Z. l. leucophrys (J. R. Forster, 1772) – C & E Canada from N Manitoba and N Ontario E through N & NC Quebec to N Labrador and N Newfoundland; winters in S & SE USA (S from Kansas, Missouri, Kentucky and North Carolina) and N Mexico (S to Sonora).
  • Z. l. pugetensis Grinnell, 1928 – extreme SW Canada (SW British Columbia) S along US coast to NW California; non-breeding S to SW California.
  • Z. l. nuttalli Ridgway, 1899 – coastal & C California (from Mendocino County S to Santa Barbara County).
  • Z. l. oriantha Oberholser, 1932 – mountains of SW Canada (SE British Columbia, S Alberta and extreme SW Saskatchewan) and W USA (N Idaho S through SC Oregon to C & E California and SC Nevada, E to Wyoming, Utah, Colorado, CE Arizona and N New Mexico); non-breeding SW USA (S California and S Arizona E to C Texas) and Mexico (S to S Baja California, Jalisco, Michoacán, Querétaro, San Luis Potosí and Nuevo León).
