Conservation
Listed as Least Concern on the IUCN Red List. Populations are generally stable, though localized declines occur due to habitat fragmentation, road mortality, and intentional killing.
Physical Description
Predominantly dark brown to glossy black coloration with faint blotches or remnants of a patterned juvenile phase visible on the sides and back. The head is distinct from the neck, eyes feature round pupils, and the scales are weakly keeled with a somewhat flattened ventral body profile.
Size & Dimensions
The specimen shown is likely a subadult or small adult measuring approximately 3 to 4 feet. Typical adults range from 42 to 72 inches (107 to 183 cm), with maximum recorded lengths approaching 84 inches.
Habitat
Inhabits a wide variety of habitats including deciduous and coniferous forests, rocky hillsides, farmland, swamps, and suburban areas. Highly adept at climbing trees and structures, often found near barns or abandoned buildings.
Diet & Feeding
Diet consists primarily of rodents, small mammals, birds, and bird eggs. They are agile climbers that frequently raid bird nests and employ constriction to subdue active prey before ingestion.
Reproduction
Oviparous species that typically breeds in the spring. Females lay clutches ranging from 6 to 30 eggs in rotting logs, mulch piles, or underground cavities during mid-summer, with incubation lasting around 60 to 65 days.
Conservation Status
Listed as Least Concern on the IUCN Red List. Populations are generally stable, though localized declines occur due to habitat fragmentation, road mortality, and intentional killing.
Cultural Significance
Highly beneficial to agriculture and human settlements due to their exceptional proficiency in controlling rodent populations, earning them favor among farmers and naturalists.
Notable Features
Exceptional climbing ability facilitated by specialized belly scales that provide traction on vertical surfaces, along with the behavior of kinking the body into an accordion shape when threatened.
