Conservation
Least Concern (IUCN); however, they are frequently killed by humans who mistake them for venomous copperheads or rattlesnakes.
Physical Description
Stout-bodied with smooth, shiny scales. Features a gray to tan ground color with rows of reddish-brown or chocolate-brown blotches outlined in black. A characteristic 'V' or 'Y' shaped light mark is often present on the back of the head/neck.
Size & Dimensions
The specimen appears to be an adult approximately 24-36 inches (60-91 cm) in length. Typical species range is 24 to 52 inches (61-132 cm).
Habitat
Found in a wide variety of habitats including fields, woodlands, rocky hillsides, and farm outbuildings. They are common in anthropogenically altered environments and are often found under cover like logs or boards.
Diet & Feeding
Active foragers that utilize constriction. Their diet is diverse, consisting of rodents, birds, eggs, and other snakes (including venomous species).
Reproduction
Oviparous (egg-laying). Females lay clutches of 2 to 17 eggs in early summer, tucked into rotting logs, leaf litter, or compost pails, which hatch in late summer.
Look-alikes
Commonly confused with the Eastern Copperhead (Agkistrodon contortrix), which has hourglass-shaped bands and keeled scales, and the Northern Watersnake (Nerodia sipedon), which is much more robust with keeled scales.
Conservation Status
Least Concern (IUCN); however, they are frequently killed by humans who mistake them for venomous copperheads or rattlesnakes.
Cultural Significance
Named 'milksnakes' due to an old folk myth that they would sneak into barns to suck milk from cows; in reality, they are attracted to barns for the abundance of rodent prey.
Notable Features
Their smooth, glossy scales and vivid blotched pattern make them one of the more visually striking snakes in the Northeast. They are highly beneficial to farmers for natural rodent control.
