10 Facts About the Copperhead Snake

The Copperhead Snake (Agkistrodon contortrix) is one of the most common snake species in North America.

The Copperhead Snake (Agkistrodon contortrix) is one of the most common snake species in North America. Their venom is fairly weak, and the bites almost never end up fatal for people. Still, they bite frequently, so here are 10 facts about the Copperhead snake if you ever come across one.


As the name tells us, the head of the Copperhead is in vibrant copper-red color. Copperhead Snake is a pit viper, and another characteristic of that species is that they have a small pit between the eyes and the nostrils, which serves as a heat-sensor. They use that pit to detect warm-blooded animals before they strike.


Copperheads are considered to be medium-sized snakes, with their length being around 2 or 3 feet. Females are a bit longer than males, but males have longer tails. Their bodies are pretty thick and sturdy.

Head Shape

The head of a Copperhead snake is in the shape of a triangle. There is a noticeable ridge that separates the top of their heads from the eyes and nostrils. The pupil of a Copperhead is positioned vertically, and the color of the iris is mostly orange but can be in a reddish-brown shade.

Scaled Body Pattern

Like many of the other snakes, Copperheads also have scales over their bodies. This is the so-called ”dorsal pattern”, where every scale is in a shape of an hourglass, changing colors from dark and red shades of brown on the top, and more lighter-pinkish colors on the back. Those scales are typically more prominent on each of the snake sides, and they become more narrow as they come towards the center or the back of the snake.

Many other snakes that are not venomous have a very similar pattern, but remember, Copperhead is the only snake that has scales shaped like an hourglass! The head of an adult Copperhead snake, however, does not have the same scaled ornamentations.

Until they reach the adult stage, young Copperhead hatchlings body patterns are grayer than anything else, and the top of their tail is in very bright yellow or green shades.

Copperhead Territory

The Copperhead snakes can be found anywhere across the southern parts of New England, all the way up to the northern parts of Mexico. They are five distinct subspecies of the Copperhead, based on the location where they live. The ones that are considered to be spread out the most are the northern specimens, who occupy the territories of Alabama, Massachusetts, and Illinois.

They are mostly found in the woods, but they are quite capable of living in other types of ecosystems, meaning they can be found in more urban areas. They can survive in rock covered areas, deserts and canyons, and basically, any setting that has both sunlight and shade.

Copperhead’s Social Life

Copperheads most commonly do their prey hunting alone, so they are defined as a semi-social snake. However, they always hibernate within some sort of a snake community. They like to return to the same den every year.

Copperheads like to hunt during the daytime in spring or fall. Still, when the summer comes, they turn into night-loving animals and catch prey using their heat-sensor. They usually leave their den in the late spring and go searching for food. They come back to hibernation in early fall. Copperheads prefer humid and warm environments, and can sometimes climb trees when searching for prey.

The Hunter’s Way

Copperheads are, in essence, predators. They mostly sit and wait and catch small prey bursting out of a bush. When they engage in a battle with bigger prey, they first bite the animal and release it. They know the venom is going to kick in soon, so they track down the victim.

Like most of the snake species, the Copperheads eat their prey whole, utilizing the flexibility of their hinged jaws. Interestingly, Copperheads eat only up to 12 times a year.

The Young Hunter’s Alternative

Young Copperheads do not have the same strengths to tackle large prey as adults, so their diet consists mostly of smaller insects. The young ones are especially good at catching caterpillars. In hunt mode, a young Copperhead lays perfectly still, with only the very top of their tail moving and attracting animals like lizards or frogs. Once the prey comes close enough, they strike because they are born with the same set of fangs and the ability to inject venom.

Mating Season

The time when Copperheads engage in mating rituals is usually between February and May, and other rounds happen from August to October. To grab the female’s attention, male Copperheads fight between themselves in a body-shoving contest. A male that loses a fight is likely never to rechallenge another male.

Females can also engage in combat to find their partner, and they will always turn down the male that does not want to put on a fight with her. After the mating is done, the female has the ability to delay fertilization for a few months, storing the sperm until the hibernation period is over.

Ovoviviparous Species

After the mating, the eggs incubate within the female. The little Copperheads are born alive, and a female Copperhead can give birth up to 18 young ones. The venom found in hatchlings is strong as the one found in adults.
