Conservation
Listed as Least Concern on the IUCN Red List due to its wide distribution, large population size, and adaptability to human-modified environments, though facing local threats from habitat fragmentation and road mortality.
Physical Description
Juvenile specimen displaying a patterned series of dark rectangular or saddle-like blotches along a lighter grey or whitish dorsum, with smaller alternating dark spots along the flanks, a slender body shape, and weakly keeled dorsal scales.
Size & Dimensions
The visible specimen is a juvenile approximately 25 to 30 centimeters in length. Typical adult size ranges from 100 to 180 centimeters, with maximum recorded lengths approaching 210 centimeters.
Habitat
Prefers wooded regions, rocky hillsides, swamp edges, agricultural fields, and suburban environments, utilizing elevated arboreal areas as well as subterranean retreats and tree cavities.
Diet & Feeding
Diet consists primarily of small rodents, birds, bird eggs, and occasionally lizards. Juveniles frequently consume small lizards, frogs, and mice, employing an active foraging strategy and constriction to subdue prey.
Reproduction
Oviparous species that typically mates in late spring. Females deposit clutches ranging from 6 to 30 eggs in rotting logs, leaf litter, or underground burrows during mid-summer, with incubation lasting approximately two months.
Look-alikes
Frequently confused with Eastern Milksnakes (Lampropeltis triangulum) and juvenile North American Racers (Coluber constrictor). Distinguished by scale keeling, subtle differences in head patterning, and rectangular blotches rather than rounded saddles.
Conservation Status
Listed as Least Concern on the IUCN Red List due to its wide distribution, large population size, and adaptability to human-modified environments, though facing local threats from habitat fragmentation and road mortality.
Cultural Significance
Highly beneficial ecologically for controlling rodent populations around agricultural and residential properties, frequently found in proximity to human habitations and barns.
Notable Features
Exhibits exceptional climbing ability, allowing both juveniles and adults to ascend vertical tree trunks, brick walls, and rafters with ease using specialized belly scales.
