![]() Their prey is made up of lizards, frogs, baby turtles, small snakes, and the nestlings of ground dwelling birds or mammals. When preparing to shed they often seek seclusion beneath ground-surface debris. Open fields, meadows, yards, and other such habitats. When amidst dead leaves and grasses this produces a sound somewhat similar to that of a disturbed rattlesnake ![]() As would befit snakes with such hunting techniques, the eyes are large and vision is acute When defensive, racers often shake or vibrate their tail. Aptly named, these fast snakes often hunt by “periscoping,” their head held well above the grasses or weeds in which they are searching for their prey of lizards, frogs, baby turtles, small snakes, and the nestlings of ground dwelling birds or mammals. Additionally, the hatchlings are lighter than the adults and usually strongly patterned with darker dorsal saddles or crossbands. ![]() The resulting offspring may mature into differently colored adults. ![]() Where ranges abut or overlap, the various subspecies of this snake often interbreed. Scales are smooth, in 17 rows to and beyond midbody, and 15 rows posteriorly. Hatchlings are lighter than the adults and are strongly patterned with darker dorsal saddles. Adult at 4 to 5 feet in length, occasionally a bit longer. This snake differs from the southern black racer only in internal characteristics.

If you see a northern black racer, MassWildlife encourages you to report your sighting using Heritage Hub, /heritagehub. 2,250 m.)

The complete story of the study, along with more black racer facts, can be found in the No. At the conclusion of the study, the snakes were recaptured, had their transmitters removed and were released, and in one case, with tragic results. The group documented home range, nesting and hibernation sites, and the vegetation communities the racers occupied. BW tracked the movements of each racer for almost a year as they moved around the island. With these threats in mind, and lack of baseline data on the species, BiodiversityWorks (BW), a non-profit headquartered on Martha’s Vineyard focused on wildlife conservation through research and monitoring, embarked on a five-year study to document racer distribution on the island, their movements, and habitat use across different landscapes.įour racers were captured using funnel traps-and named Audrey, Katama, Scooter, and Liatris-and each was implanted with a radio transmitter by a volunteer veterinarian. The Massachusetts State Wildlife Action Plan ranks the black racer as common across the state, but it is of concern because little is known about their current abundance and distribution. As with many other species, black racers are at risk from habitat loss and fragmentation, and anecdotal information indicates the species is declining in our region. Sadly, encounters with black racers are declining in New England. Seeing a five-foot long northern black racer ( Coluber constrictor) hunting in a meadow or climbing a shrub can be a memorable wildlife encounter where responses range from wonder to heart-stopping fear.
