The Curve-billed Thrasher (Toxostoma curvirostre) is native primarily to the southwestern United States and northern and central Mexico. Its geographical range includes parts of Arizona, New Mexico, Texas, and the Mexican states of Sonora, Chihuahua, Coahuila, and as far south as Puebla and Hidalgo.

The Curve-billed Thrasher typically inhabits arid and semi-arid regions, often characterized by desert scrub, thorn scrub, and desert grasslands. It thrives in environments with cacti, such as saguaro and prickly pear, as well as mesquite and other desert shrubs. The climate in these areas is generally hot and dry with limited rainfall.

This bird species is well adapted to desert environments, feeding on a varied diet that includes insects, small invertebrates, fruits, and seeds. Its robust curved bill is adapted for digging into the ground to uncover food. The Curve-billed Thrasher is known for its ability to survive on minimal water, obtaining necessary moisture from its diet. It occupies a crucial role in its ecosystem by contributing to seed dispersion and controlling insect populations.
