Global Range
CE - 250-20,000 square km (about 100-8000 square miles) - CDE - BREEDING: southwestern Washington south through mountains to southern California and west-central Nevada. Populations fragmented within range (AOU 1983, Pearson 1997). NON-BREEDING: primarily from Durango and southern Nuevo Leon south to Oaxaca, from Chiapas to Guatemala, and southern Honduras to western Nicaragua (Pearson 1997). Rare and/or local in coastal California (from central California south) and in west-central Nicaragua and Costa Rica; accidental to western Panama (AOU 1983, Stiles and Skutch 1989, Pearson 1997). Highest densities in Central Volcanic Belt of Mexico (Howell and Webb 1995). MIGRATION: through Sonora, Chihuahua, San Luis Potosi, and rarely northern Baja California.
