 The curve-billed thrasher (Toxostoma curvirostre) is a medium-sized mimid that is a member of the genus Toxostoma, native to the southwestern United States and much of Mexico. Referred to as the default desert bird, it is a non-migratory species. Several subspecies have been classified since 1827, though there is no consensus on the number. Allopatric speciation is believed to have played a major role in the variations of the curve-billed. It shares striking similarities in appearance with another Toxostoma member, Bendire's thrasher. Nevertheless, it is recognized for its grey color and sickle-shaped bill. It generally resides in desert regions of the United States and Mexico, but can inhabit areas predominately populated by humans.
