Conservation
IUCN Status: Least Concern. Populations are stable, though threatened by habitat fragmentation and persecution by humans.
Physical Description
Distinctive 'hourglass' or saddle-shaped crossbands that are thinner on the spine and wider on the sides. Background color is tan, copper, or gray. Triangular head, vertical pupils (cat-like), and heat-sensing pits between eyes and nostrils.
Size & Dimensions
Typical adults range from 24 to 36 inches (61 to 91 cm). Maximum recorded length is approximately 53 inches (135 cm). This specimen appears to be an adult.
Habitat
Generalist predator found in deciduous forests, rocky hillsides, swamp edges, and suburban woodlots. Prefers terrestrial microhabitats with heavy leaf litter for camouflage.
Diet & Feeding
Opportunistic carnivore. Consumes small rodents, frogs, lizards, birds, and large insects (such as cicadas). Uses an 'ambush and strike' strategy, injecting venom and then tracking the trail.
Reproduction
Ovoviviparous (gives birth to live young). Typical litter size is 2 to 10 young, usually born in late summer or early fall. Juveniles have bright sulfur-yellow tail tips.
Look-alikes
Commonly confused with North American Watersnakes (Nerodia spp.), which have dark bands that are widest at the top (saddle shape reversed) and round pupils, and Eastern Milk Snakes which have different patterning.
Conservation Status
IUCN Status: Least Concern. Populations are stable, though threatened by habitat fragmentation and persecution by humans.
Cultural Significance
Often subject to human fear and misunderstanding; ecologically vital for controlling rodent populations and maintaining the balance of forest floor ecosystems.
Notable Features
The copperhead is famous for its 'Hershey Kiss' pattern when viewed from the side and its incredible cryptic coloration that makes it nearly invisible in leaf litter.
