The curve-billed thrasher (Toxostoma curvirostre) is a medium-sized mimid native to most of Mexico and to the deserts of southwestern United States. It is a non-migratory species, and throughout most of its range it is the most common desert thrasher. 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 is grey-brown overall with a slightly curved bill, and is similar in appearance to the related Bendire's thrasher. It generally resides in desert regions of the United States and Mexico, but can inhabit areas predominately populated by humans. Wikipedia →
