Conservation
Listed as Least Concern on the IUCN Red List. They are locally common and adaptable to human-modified habitats, though they face mortality from vehicular traffic and intentional persecution.
Physical Description
Features a pattern of dark brown or black blotches on a lighter gray, brown, or yellowish-gray background. The head is relatively distinct from the neck with large eyes, and the body may have a slightly loaf-shaped cross-section. Scales are weakly keeled.
Size & Dimensions
This specimen appears to be a juvenile measuring approximately 30 to 45 cm in length. Adults typically range from 107 to 183 cm, with some individuals growing even larger.
Habitat
Inhabits a wide variety of environments including deciduous forests, agricultural fields, wooded hillsides, rocky outcrops, and suburban areas with mature trees or outbuildings. Highly adaptable and capable of climbing trees and vertical structures.
Diet & Feeding
Diet consists primarily of rodents, birds, bird eggs, and occasionally small reptiles. They are adept climbers and active foragers that use constriction to subdue active prey.
Reproduction
Oviparous species that typically breeds in the spring. Females lay clutches ranging from 6 to 30 eggs in rotting logs, under rocks, or in loose soil during early summer, with incubation lasting around two months.
Look-alikes
Frequently confused with Eastern Milksnakes, Foxsnakes, and copperheads due to the blotched pattern. Unlike venomous pit vipers, they lack facial pits and have rounded pupils.
Conservation Status
Listed as Least Concern on the IUCN Red List. They are locally common and adaptable to human-modified habitats, though they face mortality from vehicular traffic and intentional persecution.
Cultural Significance
Highly beneficial to human agriculture and human settlements due to their role in controlling rodent populations, though they are frequently misidentified and killed out of fear.
Notable Features
Known for exceptional climbing ability, often found scaling brick walls, trees, and rafters. When startled, they may freeze in a wavy or kinked posture to break up their outline.
