The roadrunners (genus Geococcyx), also known as chaparral birds or chaparral cocks, are two species of fast-running ground cuckoos with long tails and crests. They are found in the southwestern and south-central United States, Mexico and Central America,[2][3] usually in the desert. Although capable of flight, roadrunners generally run away from predators. On the ground, some have been measured at 32 km/h (20 mph).
