Curve-billed Thrasher

The Curve-billed Thrasher is a common desert songbird found across the southwestern United States and much of Mexico, recognized by its long, distinctly down-curved bill used for probing soil and leaf litter. It is a familiar resident of desert scrub, especially areas with abundant cholla and other cacti used for nesting.

Flight feathers: grayish-brown, fairly broad and rounded at the tips, adapted for short bursts of flight rather than long-distance travel. Tail feathers: long and graduated, grayish-brown, sometimes with faint pale tips on the outer feathers. Body feathers: grayish-brown overall with faint, diffuse spotting on the breast that is less distinct than in some other thrashers. The orange-yellow eye is a useful accompanying field mark. Compared to the California Thrasher, Curve-billed Thrasher feathers are paler grayish-brown rather than dark chocolate brown, and the bill curvature is less extreme.

Sexes look alike. Adults are grayish-brown above and below, with faint, blurry spotting on the breast, pale wing bars formed by whitish tips on the greater coverts, and an orange to yellow eye. Juveniles show duller plumage with less distinct spotting and a darker eye that lightens with age. There is no strong seasonal plumage variation.

Curve-billed Thrashers inhabit desert scrub, thorn scrub, and cactus-rich habitats across the southwestern United States and much of Mexico, often found in areas with cholla cactus used for nesting and cover. The species is generally non-migratory, remaining resident year-round within its range.

This thrasher forages mainly on the ground, using its curved bill to flip aside soil, leaf litter, and debris in search of insects and other invertebrates, and also takes plant material seasonally. It builds a bulky twig nest, often within the protective spines of cholla or other cacti. Its calls include a sharp, whistled 'whit-wheet' contact call, and its song is a long series of varied, often repeated musical phrases.
