Conservation
IUCN Red List status is Least Concern. Populations are generally stable, though local threats include habitat fragmentation and road mortality.
Physical Description
Displays a striking juvenile pattern of dark grey or black blotches over a lighter grey or whitish background color. The head typically features distinct dark markings, and the body has weakly keeled scales with a slender profile.
Size & Dimensions
This individual appears to be a juvenile measuring approximately 30 to 45 cm in length. Adults typically grow to between 100 and 183 cm.
Habitat
Found in a wide variety of habitats including deciduous forests, rocky wooded hillsides, agricultural fields, and suburban areas. They are semi-arboreal and frequently ascend trees.
Diet & Feeding
Primarily feeds on small rodents, birds, and bird eggs. Juveniles often consume lizards and small frogs. They are active foragers that subdue prey using constriction.
Reproduction
Oviparous, laying clutches ranging from 6 to 30 eggs typically in mid-summer within rotting logs, under rocks, or in loose soil. Incubation lasts about two months.
Look-alikes
Frequently confused with other rat snake species (like Pantherophis alleghaniensis or Pantherophis guttatus) and occasionally juvenile racers (Coluber constrictor), which lack the distinctive saddle blotches as they mature.
Conservation Status
IUCN Red List status is Least Concern. Populations are generally stable, though local threats include habitat fragmentation and road mortality.
Cultural Significance
Valued in agricultural settings and rural areas as natural pest control due to their efficiency in managing rodent populations.
Notable Features
Known for their exceptional climbing ability, often found vertically on brick walls or high up in trees. When threatened, they may kink their bodies into a series of accordion-like S-shapes.
