Conservation
IUCN Red List status is Least Concern, though localized populations face threats from habitat fragmentation, road mortality, and intentional killing.
Physical Description
Displays a pattern of dark brown to black blotches running along a lighter brownish or greyish dorsal background. The head is relatively distinct from the neck, and the scales are weakly keeled.
Size & Dimensions
Estimated specimen length is approximately 4 feet. Typical adult size ranges from 3.5 to 6 feet, with maximum lengths exceeding 7 feet.
Habitat
Highly adaptable, inhabiting deciduous forests, rocky wooded hillsides, agricultural fields, swamp margins, and suburban areas. They are accomplished climbers and often found near human structures.
Diet & Feeding
Diet consists primarily of rodents, small mammals, birds, and bird eggs. They are active hunters and constriction specialists that dispatch prey by wrapping around it.
Reproduction
Oviparous species, females typically lay clutches ranging from 12 to 20 eggs in mid-summer within decaying vegetation, hollow logs, or loose soil.
Look-alikes
Frequently confused with other rat snakes in the Pantherophis complex, eastern racers, and occasionally various large watersnakes or milksnakes depending on geographic region.
Conservation Status
IUCN Red List status is Least Concern, though localized populations face threats from habitat fragmentation, road mortality, and intentional killing.
Cultural Significance
Highly beneficial ecologically for controlling rodent populations around farms and human habitations, though they are sometimes mistakenly feared due to misidentification.
Notable Features
Exceptional climbing ability allowing them to scale vertical brick walls and tall trees easily, and a defensive behavior of freezing or vibrating the tail to mimic rattlesnakes.
