The greater roadrunner (Geococcyx californianus (renkoekoek)) is a long-legged bird in the cuckoo family. The roadrunner is an opportunistic omnivore. Its diet normally consists of insects (such as grasshoppers, crickets, caterpillars, and beetles), small reptiles (such as lizards, collared lizards, and snakes, including rattlesnakes), rodents and small mammals, spiders (including tarantulas), scorpions, centipedes, snails, small birds (and nestlings), eggs, and fruits and seeds.
