Overview
Sometimes informally called the 'copperhead rattlesnake,' this species is actually a true copperhead, a pit viper closely related to rattlesnakes and cottonmouths but lacking a rattle. It is one of the most commonly encountered snakes in the eastern United States, often found in suburban woodlands and gardens.
Copperheads rely heavily on camouflage and often hold still rather than fleeing.
How to identify it
- Coppery tan to pinkish-brown body with darker hourglass or saddle-shaped crossbands
- Broad, triangular, coppery-colored head distinct from the neck
- Vertical pupils and visible heat-sensing pits
- No rattle on the tail, distinguishing it from true rattlesnakes
- Distinguished from young cottonmouths and other patterned snakes by the hourglass-shaped bands, narrower in the middle
Habitat & range
Found in deciduous forests, rocky hillsides, wetland edges, and increasingly suburban areas across the eastern and central United States, often near woodpiles, rock outcrops, and leaf litter.
Behavior, diet & reproduction
Primarily nocturnal in warm months, more diurnal in cooler weather. Feeds on rodents, insects, amphibians, and small reptiles. Relies heavily on camouflage, often remaining motionless rather than fleeing when approached. Ovoviviparous, giving birth to live young in late summer or fall.
