Conservation
Evaluated as Least Concern on the IUCN Red List. Faces threats primarily from habitat fragmentation, vehicular mortality on roads, and direct persecution by humans due to fear.
Physical Description
Displays a light gray to tan background coloration with darker blotches or saddles along the back, which can darken into brownish or blackish tones depending on the regional variation. The head is relatively distinct from the neck, and the body possesses weakly keeled scales with a somewhat flattened ventral appearance allowing for exceptional climbing ability.
Size & Dimensions
The specimen shown is estimated to be a sub-adult or adult around 4 to 5 feet long. Typical adult size ranges from 3.5 to 6 feet, with maximum recorded lengths exceeding 7 feet.
Habitat
Inhabits a wide variety of habitats including deciduous forests, rocky hillsides, agricultural fields, swamp margins, and suburban areas. Highly adaptable, frequently found climbing trees or utilizing human-made structures such as old barns, fences, and outbuildings.
Diet & Feeding
Predominantly feeds on small mammals such as mice, rats, and voles, as well as birds and their eggs. Utilizes constriction to subdue active prey and is an agile climber capable of locating prey in elevated locations.
Reproduction
Oviparous species that typically mates in the spring. Females deposit clutches ranging from 10 to 20 or more eggs in hidden, humid locations such as rotting logs, leaf litter, or beneath flat rocks during mid-summer.
Look-alikes
Frequently confused with other large colubrids such as the Eastern Milksnake, Foxsnake, or Racer, but can be distinguished by its blotched pattern, scale texture, and tendency to kink its body into an accordion shape when threatened.
Conservation Status
Evaluated as Least Concern on the IUCN Red List. Faces threats primarily from habitat fragmentation, vehicular mortality on roads, and direct persecution by humans due to fear.
Cultural Significance
Plays a vital ecological role in regulating rodent populations in both natural ecosystems and agricultural areas, making them highly beneficial neighbors to farmers and landowners.
Notable Features
Known for the 'accordion' defensive posture visible in the image, where the snake folds its body into a series of tight S-shaped curves to break up its outline, and an ability to scale vertical surfaces with ease.
