Regional Differences
Curve-billed Thrashers from the Sonoran Desert (known as the palmeri group) have grayer chests with very indistinct spots and dull wingbars, whereas the curvirostre group of the Chihuahuan Desert has more distinct spots on a paler breast, with whitish wingbars and more white in the outer tail feathers.
