Don't confuse with the Cactus Wren. Gives a harsh, rapid, unmusical "chur-chur-chur" song like an old car that won't start, not the roadrunner's descending series of dovelike coos.

Where you'll hear it

Year-round resident from California’s Central Valley, Nevada, Utah, and Colorado south through Texas and most of Mexico, with highest densities in the Sonoran and Chihuahuan Deserts.

Arid and semi-arid landscapes including desert scrub, chaparral, mesquite flats, open grasslands with scattered shrubs, and edges of agricultural fields; often seen darting across roads and dry washes.

Mostly sedentary; pairs defend territories all year. Some juveniles disperse short distances after fledging. Breeding peaks March–June with a possible second nest in wet years.

How to recognize it by sight

The Greater Roadrunner is a large, long-legged cuckoo built for speed on the ground. With a shaggy crest, streaked brown-and-buff plumage, and an outsized balancing tail, this desert icon can run about 15 mph and may sprint faster while chasing lizards, snakes, and insects.
