Roadrunners are fast-running birds belonging to the family Cuculidae. They are primarily found in the deserts and arid regions of the southwestern United States and Mexico. Known for their distinctive long legs, a long tail, and a unique crest on their head, these birds can reach speeds of up to 20 miles per hour. They are often seen running along the ground rather than flying. These birds are omnivorous, feeding on insects, small mammals, and reptiles. Their diet includes creatures like lizards and grasshoppers. Roadrunners are also known for their unique mating rituals, which involve elaborate displays and vocalizations.
