Conservation
Least Concern according to the IUCN Red List, though local populations face pressures from habitat fragmentation, road mortality, and intentional killing due to human fear.
Physical Description
Displays dark blotches along a lighter background, sometimes appearing heavily melanistic or dark-colored as an adult. Head is somewhat distinct from the neck with large eyes and round pupils. Scales are weakly keeled, and the body is moderately robust with a slightly flattened belly profile for climbing.
Size & Dimensions
Estimated specimen length is approximately 3 to 4 feet. Adults typically range from 3.5 to 6 feet (105 to 180 cm) in total length, with maximum records approaching 7 feet.
Habitat
Inhabits a wide range of environments including deciduous and mixed forests, rocky wooded hillsides, agricultural fields, and suburban areas. Known for exceptional climbing ability, frequently found in trees, old barns, and attics.
Diet & Feeding
Preys primarily on small rodents, birds, bird eggs, and bats. Employs an active foraging and climbing strategy, subduing larger prey through constriction and smaller prey directly.
Reproduction
Oviparous, typically mating in the spring and laying clutches of 10 to 20 eggs in decaying wood, leaf litter, or underground cavities during summer. Eggs hatch after approximately 2 months.
Conservation Status
Least Concern according to the IUCN Red List, though local populations face pressures from habitat fragmentation, road mortality, and intentional killing due to human fear.
Cultural Significance
Highly beneficial ecologically for controlling rodent populations around agricultural and residential areas, often serving as a natural pest control agent.
Notable Features
Exhibits a behavior of kinking its body into an accordion-like S-shape and freezing or vibrating its tail when cornered, and possesses specialized belly scales that aid in vertical climbing on rough surfaces.
