Occurs from southern California, Arizona, New Mexico, and west Texas south into northern and central Mexico, especially in the Sonoran and Chihuahuan Desert regions. Prefers dense desert scrub with mesquite, catclaw acacia, cholla, and other thorny shrubs, as well as riparian thickets along washes and arroyos.

Named for its bright rufous crissum (undertail coverts), the crissal thrasher is more often heard than seen as it skulks in dense thorny thickets. It uses its long, decurved bill to sweep aside leaf litter and probe soil for prey. Pairs defend year-round territories and often stay together across seasons.
Temperament
secretive and territorial
Flight Pattern
short rapid wingbeats with low, direct flights between cover
Social Behavior
Typically observed as solitary birds or in mated pairs that maintain year-round territories. Monogamous pairs nest low in thorny shrubs, building bulky stick nests. Clutches are usually 2–4 eggs, and both parents participate in care.
Migratory Pattern
Resident
Song Description
A rich, mellow, and varied series of whistles and phrases, often delivered from a concealed perch within dense shrubs. Also gives sharp chaks and harsh scolds when alarmed.
