Conservation
IUCN Red List status is Least Concern, due to their wide distribution and high adaptability to human-altered environments, though localized threats include road mortality and habitat destruction.
Physical Description
Features a patterned back with dark gray, brown, or black blotches over a lighter gray or tan background color. The head is relatively distinct from the neck with dark markings often forming a spear-point or dart shape on top. Scales are weakly keeled and the body is somewhat loaf-shaped in cross-section.
Size & Dimensions
This specimen appears to be a juvenile, roughly 10 to 15 inches in length. Adults typically reach lengths of 42 to 72 inches (106 to 183 cm), with exceptional individuals growing even larger.
Habitat
Found in a wide variety of habitats including deciduous forests, wooded hillsides, agricultural fields, swamp edges, and suburban areas. Highly adaptable and arboreal, often utilizing trees, rock outcrops, and abandoned structures.
Diet & Feeding
Diet consists primarily of small rodents, birds, bird eggs, and bats. They are capable constrictors, using constriction to subdue active prey, and are exceptionally skilled climbers capable of scaling vertical tree trunks and brick walls.
Reproduction
Oviparous, laying clutches ranging from 10 to 30 eggs typically in mid-summer within rotting logs, leaf litter, or loose soil. Incubation period lasts approximately 60 to 75 days.
Conservation Status
IUCN Red List status is Least Concern, due to their wide distribution and high adaptability to human-altered environments, though localized threats include road mortality and habitat destruction.
Cultural Significance
Highly beneficial to agriculture and human settlements due to their proficiency in controlling rodent populations. Frequently encountered around rural and suburban properties.
Notable Features
Juveniles of this species often display much brighter and more contrasting patterns than adults, which tend to darken or fade as they mature. They are also known for freezing when approached or kinking their bodies into a series of accordion-like curves.
