The northern black racer (Coluber constrictor constrictor) is a subspecies of the eastern racer (Coluber constrictor), a nonvenomous snake in the family Colubridae. Their geographic range extends from southern Maine to northern Georgia and westward to central Kentucky and eastern Ohio. Their occupancy is dependent on the availability of large patches of open habitats.[4]
Geographic range
Coluber constrictor constrictor ranges from Georgia, Alabama, and Mississippi in the south, to central New York, Vermont, New Hampshire, and Maine in the north, to Tennessee , Kentucky, and eastern Ohio in the west. At the southern end of its range, it overlaps with Coluber constrictor priapus, the southern black racer, and at the westward end it overlaps with Coluber constrictor flaviventris, the eastern yellow-bellied racer.[5]
Habitat
Northern black racer are a terrestrial species and are found in open, grassy areas or in open forest adjacent to grassy areas. They prefer dryer habitats. They will inhabit urban and agricultural areas, barrier islands, and grasslands in mountains. The Northern black racer will seek refuge under objects like logs, rocks, and other debris during the night or on cool days.[6]
