The Curve-billed Thrasher is normally a bird of the arid Southwest, and only rarely ranges outside of that region. They are extremely rare visitors to South Dakota. They are less shy than some of the other Thrashers, and are even a common sight in residential areas of the Southwest, provided their favorite breeding site, cholla cacti, are available. Of the large thrashers of the arid Southwest, the Curve-billed is the most common and well known.
Habitat
Found in desert habitats of the Sonoran desert, although it avoids the driest of locations with little or no vegetation. Also found in arid brushlands of the Southwestern U.S., and in suburban areas.
Diet
Insects and berries. Also feeds on the seeds of prickly-pear and saguaro cactus.
Behavior
Primarily forages along the ground, digging in the soil with its beak, turning over rocks, or chasing insects.
Breeding
Non-breeder in South Dakota. In range, the nest is a large cup of twigs, grasses, feathers, and other material, usually built in a cactus such as a cholla cactus, or sometimes in a shrub or small tree. The female lays between 2 and 4 eggs, and both parents help to incubate them. Upon hatching, both parents help to feed the young. They will often raise more than one brood per breeding season.
Song
Repeated clear warbling phrases.
Migration
A permanent resident of the southwestern United States and Mexico, they rarely wander outside of their normal range.
