In the fall, copperheads return to their dens for winter hibernation.
The northern copperhead can be found almost anywhere, but it is most often encountered on rocky hillsides or wooded mountainous areas. Copperheadsare the most active from April to October, through the daylight hours. Theybecome nocturnal when the weather gets warmer. They remain in the area of hibernation for sometime after emergence.
A copperhead's diet consists of rodents, frogs, insects, and lizards. The northern copperhead is reluctant to strike unless it is provoked. The bites arenot severe when medical treatment is performed.
