It inhabits the desert regions of Arizona, California, Colorado, New Mexico, Nevada, Utah, Texas, and Sonora; also New Mexico-border Chihuahua and the Colorado River region of Baja California. The Gambel's quail is named in honor of William Gambel, a 19th-century naturalist and explorer of the Southwestern United States.
