Conservation
Listed as Least Concern by the IUCN Red List due to its wide distribution, large overall population, and high adaptability to human-modified environments.
Physical Description
Displays a dark brown to nearly black background coloration with faint or fading blotches visible along the back. The scales are weakly keeled, and the body exhibits a somewhat loaf-shaped cross-section. Head is slightly distinct from the neck.
Size & Dimensions
Estimated specimen length is approximately 4 to 5 feet (120 to 150 cm). Typical adult size ranges from 3.5 to 6 feet (106 to 183 cm), with maximum recorded lengths approaching 7 feet.
Habitat
Inhabits a wide variety of habitats including deciduous and coniferous forests, rocky wooded hillsides, agricultural fields, swamp margins, and suburban areas. Highly adaptable and frequently utilizes elevated perches such as trees and old barns.
Diet & Feeding
Preys primarily on small mammals such as mice, rats, and voles, as well as birds, bird eggs, and occasionally bats. Employs constriction to subdue active prey and is an agile climber capable of locating nests in trees.
Reproduction
Oviparous species that mates in the spring (April to June). Females deposit clutches typically ranging from 10 to 20 eggs in hidden, humid locations such as rotting logs, compost heaps, or underground burrows during mid-summer.
Conservation Status
Listed as Least Concern by the IUCN Red List due to its wide distribution, large overall population, and high adaptability to human-modified environments.
Cultural Significance
Valued ecologically as a natural form of pest control, significantly reducing rodent populations around agricultural and residential areas. Often encountered around rural properties.
Notable Features
Noted for exceptional climbing ability, often found high up in trees or rafters. When startled, they may freeze, kink their bodies into a series of accordion-like S-shapes, or emit a strong-smelling musk.
