Conservation
IUCN Red List status is Least Concern, though localized populations face threats from habitat fragmentation, road mortality, and intentional killing.
Physical Description
Features a light grey or tan background color with distinct dark brown or reddish-brown blotches along the back and smaller alternating spots on the sides. The head shows a typical light-colored 'Y' or 'V' shaped marking near the neck. Scales are smooth and glossy.
Size & Dimensions
The specimen shown is likely a juvenile or subadult, approximately 12 to 18 inches in length. Adults typically range from 24 to 50 inches.
Habitat
Inhabits a wide variety of habitats including deciduous and coniferous forests, fields, agricultural lands, rocky hillsides, and suburban areas, typically ranging from sea level to moderate elevations.
Diet & Feeding
Preys primarily on small rodents, lizards, birds, and occasionally other snakes. Hunts actively or waits in ambush, subduing prey via constriction.
Reproduction
Oviparous, laying clutches typically ranging from 6 to 18 eggs in rotting logs, under rocks, or in loose soil during early summer.
Look-alikes
Frequently confused with copperheads or other rat snakes due to the blotched dorsal pattern, but can be distinguished by the smooth scales, round pupils, and distinct head markings.
Conservation Status
IUCN Red List status is Least Concern, though localized populations face threats from habitat fragmentation, road mortality, and intentional killing.
Cultural Significance
Often encountered near human habitations and old barns where rodents are plentiful; historically subject to the old folk myth that they milk cows, which is entirely false.
Notable Features
Known for its docile nature when handled, though it may vibrate its tail and strike defensively if cornered or threatened.
