Black-Throated Gray Warbler

Setophaga nigrescens

The Black-Throated Gray Warbler breeds in western North America, its range extending from southwestern British Columbia along the Pacific coast south to southern California, and the mountains of northern Baja California (Mexico). The breeding range extends east to include the Great Basin, and the southwestern Rocky Mountain states. They spend winters mostly in Mexico.

Formerly classified as a member of Dendroica (wood warbler), the genus of many new world warblers was changed in 2011, when geneticists weighed in with results of ongoing studies of avian genomes. The new genus for this bird is Setophaga (moth eater).

No subspecies for this bird have been officially recognised.
