Global Range
G - 200,000-2,500,000 square km (about 80,000-1,000,000 square miles) - G - Nesting range extends from southeastern Alaska and northwestern and central British Columbia (including Queen Charlotte and Vancouver islands) south to southwestern California (generally west of Cascades and Sierra Nevada) and mountains of northern and southern Baja California (AOU 1998, Lowther 2000). Range in southeastern British Columbia, Alberta, and north-central and northeastern Washington is uncertain and in need of further study. Winter range is mainly along Pacific coast lowlands of Mexico (0-1,500 meters elevation) from southern Baja California and northwestermn Mexico (southern Sonora) south to Oaxaca west of the Isthmus of Tehuantepec, rarely north to California and Arizona (Howell and Webb,1995, AOU 1998, Lowther 2000).<br><br>The <i>insulicola </i>group is resident in the Channel Islands off southern California (AOU 1989).<br><br>Coded range extent refers to nesting range.
