Conservation
IUCN Red List status is Least Concern. Populations are generally stable, though local threats include habitat fragmentation, road mortality, and intentional killing.
Physical Description
The specimen shows dark grey to black coloration with faint lighter blotches or white interstitial skin visible between scales. The scales are moderately keeled, giving a textured appearance. The head is broad and distinct from the neck, with round pupils.
Size & Dimensions
Estimated length of this specimen is approximately 3.5 to 4 feet. Typical adults reach lengths of 3.5 to 6 feet (42 to 72 inches), with record lengths exceeding 7 feet.
Habitat
Inhabits a wide variety of habitats including deciduous forests, rocky wooded hillsides, agricultural fields, and suburban areas. Frequently utilizes trees and rocky outcrops, typically found from sea level up to moderate elevations.
Diet & Feeding
Diet consists primarily of rodents, small mammals, birds, and bird eggs. They are active foragers and skilled climbers that use constriction to subdue their prey.
Reproduction
Oviparous species that typically breeds in the spring. Females lay clutches ranging from 10 to 30 eggs in rotting logs, under rocks, or in loose soil during the summer months, with incubation lasting around 60 to 65 days.
Look-alikes
Frequently confused with other ratsnake species such as the Eastern Ratsnake (Pantherophis quadrivittatus) and Black Racer (Coluber constrictor). Racers can be distinguished by their smooth scales and lack of patterned or light-speckled interstitial skin.
Conservation Status
IUCN Red List status is Least Concern. Populations are generally stable, though local threats include habitat fragmentation, road mortality, and intentional killing.
Cultural Significance
Highly beneficial to agriculture and human settlements due to their proficiency in controlling rodent populations, serving an important ecological role as natural pest regulators.
Notable Features
Exhibits exceptional climbing agility, capable of scaling vertical brick walls and mature trees with ease. Often freezes when approached or kinks its body into an accordion-like pattern.
