Conservation
IUCN Red List status is Least Concern. Main threats include habitat fragmentation, road mortality, and intentional killing due to fear or misunderstanding.
Physical Description
Features a dark brown to blackish dorsal pattern with irregular blotches or saddles of lighter brown, yellowish, or olive tones. The belly is typically checkered or mottled with white, grey, and black. Body is relatively slender with a somewhat flattened appearance to the underside (loaf-shaped cross-section) aiding in climbing.
Size & Dimensions
Estimated length of this specimen is approximately 3 to 4 feet. Typical adults range from 42 to 72 inches (106 to 183 cm), with maximum recorded lengths approaching 84 inches.
Habitat
Highly adaptable, inhabiting deciduous and coniferous forests, rocky hillsides, swamp edges, and agricultural areas. Often found near human habitations, barns, and outbuildings, utilizing crevices, hollow trees, and foundations for shelter.
Diet & Feeding
Preys primarily on small mammals such as mice, rats, voles, as well as birds, bird eggs, and occasionally bats. Utilizes constriction to subdue active prey and is an agile climber capable of scaling vertical tree trunks and building walls.
Reproduction
Oviparous, laying clutches ranging from 12 to 20 or more eggs in early summer (June to July) within decaying logs, leaf litter, or loose soil. Eggs incubate for about 2 months before hatching in late summer or early autumn.
Conservation Status
IUCN Red List status is Least Concern. Main threats include habitat fragmentation, road mortality, and intentional killing due to fear or misunderstanding.
Cultural Significance
Provides substantial ecological value as a natural pest control agent by keeping rodent populations in check around agricultural and residential areas.
Notable Features
Exhibits exceptional climbing agility and the ability to freeze or kink its body into an accordion-like wavy pattern when startled, serving as a form of camouflage in leaf litter.
