Description: A large gray or blue snake with smooth scales. The head is usually darker than the body, though the chin and throat are white. The belly is light blue or white. Young racers are grayish, with a pattern of darker blotches and spots. Adult length: 4 to 6 feet.

Habitat and Habits: Racers inhabit a variety of places, including open woods, meadows, hedge rows, marshes, and weedy lake edges. They are alert, active snakes that may climb into low bushes to escape enemies. These snakes feed on rodents, frogs, smaller snakes, birds, and insects. Although they will bite if cornered or grabbed, racers are not venomous.

Reproduction: Females lay 6 to 25 eggs in rotting wood or underground during June and July. The young racers hatch in late summer and, as noted above, are colored differently than the adults.

Range and Status: Racers have been found through most of the Lower Peninsula (except the northernmost sections) and the southern tip of the Upper Peninsula. Once common, their numbers have fallen in many places. Needless persecution by humans as well as habitat loss are probable factors in this decline.
