Greater Roadrunner

The Greater Roadrunner is a large, ground-dwelling member of the cuckoo family, instantly recognizable by its long legs, long tail, shaggy blue-and-black crest, and streaky brown-and-white plumage that provides excellent camouflage against desert soil and brush. Rather than flying, it prefers to run, and it is among the fastest running birds in North America, capable of reaching speeds of roughly 20 mph (32 km/h) on the ground.

Behind the eye, bare skin patches of blue and orange-red are exposed in a distinctive comma-shaped mark, most visible during courtship and territorial displays. Though capable of short, low flights, the roadrunner relies overwhelmingly on its legs to travel and hunt.

Key Field Marks

• Large size with a long neck, long legs, and an extremely long, dark, white-tipped tail often carried cocked upward
• Shaggy, spiky crest atop the head
• Streaky brown, black, and white plumage overall
• Bare blue-and-orange skin patch behind the eye
• Strong, slightly downcurved bill

Similar Species

No other bird in its range shares the Greater Roadrunner's combination of large size, ground-running habit, and shaggy crest. Its distinctive silhouette and behavior make misidentification unlikely once seen.

Greater Roadrunners inhabit open, arid, and semi-arid country across the southwestern United States and much of Mexico, including desert scrub, chaparral, mesquite grassland, and increasingly suburban and agricultural edges. They are non-migratory residents, defending permanent territories year-round.

The species has slowly expanded its range eastward in recent decades, benefiting from the spread of low, shrubby habitat and human development at the edges of its historic desert range.

Roadrunners are opportunistic, aggressive predators, taking a remarkably wide range of prey including lizards, snakes (including venomous species, which they dispatch by repeatedly slamming against the ground), large insects, scorpions, small mammals, and even other birds and nestlings. They forage by running rapidly across open ground and pouncing on prey.

The voice is a descending series of soft, dove-like coos, quite different from the rapid clattering bill sound (produced by rattling the mandibles together) used in other contexts. Pairs build a platform nest of sticks low in a cactus, shrub, or small tree, and both parents help incubate eggs and feed the young. Roadrunners also conserve energy by lowering their body temperature at night and basking with exposed dark skin patches on their back to rewarm quickly at sunrise.
