![]() oaxaca, the Mexican racer, has isolated populations in New Mexico, but its main range is from south Texas to Veracruz. etheridgei, the tan racer inhabits Louisiana and Texas. anthicus, ranges from south Arkansas to Louisiana, also eastern Texas. The western yellow-bellied racer is found west of the Rocky Mountains, from southern California and Nevada through through western Colorado, Oregon, and Washington and into southern British Columbia. flaviventris, is found from extreme southern Saskatchewan southeast through Montana, western North Dakota, east to Iowa and south to Texas. latrunculus, the blackmask racer, occurs in southeastern Louisiana and adjacent Mississippi. helvigularis, occurs only in the lower Chipola and Appalachicola River valleys in Georgia and Florida. paludicola, is found only in southern Florida. It also occurs on some of the Florida Keys. priapus, the southern black racer, ranges from southern Indiana and Illinois and southeastern North Carolina to central Florida and southern Arkansas. foxii, is found from Michigan, Wisconson, and Minnesota south to Ohio, Indiana, and Illinois. Different racer subpopulations include: The northern black racer, Coluber constrictor constrictor, ranges from southern Maine and central New York south to northern Georgia and Alabama. It was funded as part of a larger State Wildlife Grant to survey and inventory amphibians and reptiles of the Wildlife Management Areas of Oklahoma: T-35-P-1.Racers occur from southern Canada to Guatemala, with considerable individual and local variation in regions where two or more subspecies intergrade (Conant and Collins, 1998).

Their small teeth cause minimal bleeding and they are nonvenomous. If grabbed, eastern racers bite immediately. Typically when these snakes “race” off, they crawl into the center of shrubs or under surface objects and seemingly disappear. Look in open areas, fields, or along edges of unpaved roads. The only other snake that moves this rapidly is the coachwhip, which is much larger. They are frequently seen on roads during morning or late afternoon and when approached, they “race” away. These are among the easiest snakes to find and observe, especially during spring. The belly is usually yellow with rows of dark spots extending along most of the belly. They also have a series of smaller blotches along the lateral surfaces of the body. Juvenile eastern racers have distinct regular blotches along the dorsal surface rather than irregular cross-markings. The two species can be distinguished by differences in dorsal and ventral color patterns. Juveniles can be confused with coachwhip juveniles. Both adults and juveniles are nervous, active snakes and usually bite immediately when handled. The background color is gray and a series of irregular dark brown blotches extend from behind the head to the tail. ![]() Juveniles differ considerably from adults. The top half will be black and the bottom half will be cream or white. Adults can be distinguished easily from other snakes in the area by keying in on the head and neck region. ![]() There are no stripes, cross bands, or blotches. The eastern yellow-bellied racer can be found statewide except the Coastal Plain region of Oklahoma and the eastern quarter of the state. Background color of the body of adults is black in eastern Oklahoma. The eastern racer can be distinguished from all other snakes in the region by a combination of smooth scales, cream to yellow belly with no marks, moderate size, and a divided anal scale.
