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). 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. The blue racer, C. c. foxii, is found from Michigan, Wisconson, and Minnesota south to Ohio, Indiana, and Illinois. C. c. priapus, the southern black racer, ranges from southern Indiana and Illinois and southeastern North Carolina to central Florida and southern Arkansas. It also occurs on some of the Florida Keys. The Everglades Racer, C. c. paludicola, is found only in southern Florida. The brownchin racer, C. c. helvigularis, occurs only in the lower Chipola and Appalachicola River valleys in Georgia and Florida. C. c. latrunculus, the blackmask racer, occurs in southeastern Louisiana and adjacent Mississippi. The eastern yellow-bellied racer, C. c. flaviventris, is found from extreme southern Saskatchewan southeast through Montana, western North Dakota, east to Iowa and south to 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. The buttermilk racer, C. c. anthicus, ranges from south Arkansas to Louisiana, also eastern Texas. C. c. etheridgei, the tan racer inhabits Louisiana and Texas. C. c. oaxaca, the Mexican racer, has isolated populations in New Mexico, but its main range is from south Texas to Veracruz.
