Roadrunner

Greater Roadrunners measure 61 cm (2 feet) in length, about half of which is tail. They have long, wobbly legs and a slender, pointed bill. The upper body is mostly brown with black streaks and sometimes pink spots. The neck and upper breast are white or pale brown with dark brown streaks, and the belly is white. A crest of brown feathers sticks up on the head, and a bare patch of orange and blue skin lies behind each eye; the blue is replaced by white in adult males (except the blue adjacent to the eye), and the orange (to the rear) is often hidden by feathers.

This bird walks around rapidly, running down prey. It mainly feeds on insects, fruit and seeds with the addition of small reptiles, small rodents, spiders, scorpions, centipedes, millipedes, small birds, their eggs, and carrion, including roadkills. It kills larger prey with a blow from the beak—hitting the base of the neck of small mammals—or by holding it in the beak and beating it against a rock. Two roadrunners sometimes attack a relatively big snake cooperatively.
Although capable of weak flight, it spends most of its time on the ground, and can run at speeds of up to 20 miles per hour (32 km/h). Cases where roadrunners have run as fast as 26 miles per hour (42 km/h) have been reported. This is the fastest running speed ever clocked for a flying bird, although it is not as fast as the flightless Ostrich.
