Racer is the name of a group of harmless, fast-moving snakes of the United States. Racers usually measure about 3½ feet (107 centimeters) long, but they sometimes grow nearly 6 feet (1.8 meters) long. Racers often climb trees to reach birds' nests, and eat the eggs and young birds. They also eat insects, frogs, small mammals such as mice, and other snakes. Some people believe racers kill large rattlesnakes, but racers never attack other snakes of their own size. When cornered, they defend themselves by biting. But they prefer to run away. Varieties There are several varieties of racers. The '' Northern Black Racer '' is found from southern Maine to central Alabama . The skin of its back is glossy and slaty-black. The belly of the northern black racer is bluish-gray, and the chin and throat are white. A bluish variety of racer, called the '' Blue Racer ,'' is found between the Great Lakes and the Ohio River. A mottled variety of racer found in Louisiana is known as the '' Buttermilk Snake ''. Racers live chiefly in the eastern United States. Varieties found west of the Mississippi Valley have tan to olive coloration on their backs. Racers are members of the common snake family, Colubridae . The scientific name for the northern black racer is ''Coluber constrictor constrictor''. Racer can refer to several genera of snakes, encompassing some 27 distinct species:
