Conservation
IUCN Red List status is Least Concern, due to its broad distribution, high adaptability to human-altered environments, and generally stable populations across its natural range.
Physical Description
The specimen displays a dark, nearly black or dark grey dorsal coloration with faint remnants of blotching visible under certain lights. The head is somewhat distinct from the neck with light labial scales, and the body appears moderately slender to robust with keeled dorsal scales typical of the genus.
Size & Dimensions
Estimated length of the visible specimen is approximately 120 cm. Typical adult size for the species ranges from 100 to 180 cm, with maximum recorded lengths exceeding 200 cm.
Habitat
Found in a wide variety of habitats including deciduous forests, agricultural edges, rocky hillsides, and suburban areas. Highly adaptable, frequently utilizing barns, abandoned structures, and forest floors with abundant leaf litter and cover.
Diet & Feeding
Diet consists primarily of rodents, small mammals, birds, and bird eggs. Hunts both actively and by ambush, utilizing constriction to subdue prey before ingestion.
Reproduction
Oviparous species. Females typically lay clutches ranging from 10 to 20 eggs in mid-summer within rotting logs, leaf piles, or loose soil, where incubation occurs naturally without parental brooding.
Look-alikes
Frequently confused with the Eastern Milksnake, Black Racer, and other ratsnake species within its range. Distinguished primarily by scale texture (weakly keeled vs smooth in racers), pattern details, and head scale configurations.
Conservation Status
IUCN Red List status is Least Concern, due to its broad distribution, high adaptability to human-altered environments, and generally stable populations across its natural range.
Cultural Significance
Highly beneficial to human environments due to its role in controlling rodent populations around agricultural and residential areas. Often referred to colloquially as a farm snake.
Notable Features
Noted for exceptional climbing ability, often found ascending vertical brick walls, trees, and rafters in search of prey or resting sites. Capable of freezing in place or kinking its body into an accordion shape when threatened.
