Which North American desert is home to the saguaro cactus and roadrunner?

The North American desert known for its saguaro cactus and roadrunner is the Sonoran Desert. It occupies parts of the southwestern United States and northwestern Mexico, including Arizona, California, Sonora, Baja California, and Baja California Sur.

The Sonoran is a hot desert, but it is not uniformly dry throughout the year. Many areas receive two seasonal rainfall periods, helping support a richer variety of plants than the neighboring Mojave or Great Basin deserts. The iconic saguaro, Carnegiea gigantea, is native to the Sonoran region and can store large amounts of water in its pleated stem.

Saguaros provide food, nesting sites, and shelter for desert wildlife. Gila woodpeckers and gilded flickers excavate cavities in their trunks, and elf owls may later use the abandoned holes. Greater roadrunners hunt insects, lizards, snakes, and small mammals across the desert landscape. The Sonoran is often confused with the Mojave or Chihuahuan deserts, but its subtropical warmth, distinctive rainfall pattern, and saguaro-rich vegetation make it a separate desert ecosystem.
