As an outdoor enthusiast, knowing which creatures are common in your vicinity and the areas you plan to visit is critical for your safety. In particular, being aware of the snake species present can save you from unforeseen and dangerous encounters. One snake to be wary of is the Copperhead snake, which is common in the United States and around the Gulf of Mexico.

While their venom isn’t particularly potent, it’s still best to avoid tangling with a Copperhead since their bites can cause significant discomfort.

Copperhead Snakes: An Uninvited Encounter

Interestingly, Copperhead snakes are responsible for the majority of snake bites in the United States. Out of the 55,000 reported snake bites each year in the country, a significant proportion, about 5,000-8,000 cases, are attributed to Copperheads. That’s a notable number, highlighting the importance of knowing how to identify this snake and avoid uncomfortable encounters.

Unraveling the Copperhead Snake

Now, you might wonder where this snake got its name from. As per the information from the PennState Extension, the Copperhead earned its name due to its copper-red head. However, it’s essential to note that the term “copperhead” is sometimes used in a more generic or non-scientific sense to refer to other snake species, like the sharp-nosed vipers, Australian copperheads, and rat snakes, all known for their distinctive radiating Moccasins.

In contrast, the North American Copperhead species (Agkistrodon contortrix) belongs to the family of rattlesnakes and pit vipers.

Home Turf of the Copperhead Snake

Copperhead snakes inhabit a variety of natural habitats in North America, predominantly found in deciduous forests and woodlands, often nestled among rock outcroppings and ledges. You might also stumble upon them in swampy or lowland regions.

In the colder winter months, these snakes hibernate within limestone crevices and dens, often sharing space with Rattlesnakes and black rat snakes. Around the USA and the Gulf of Mexico, you might find these snakes concealed in coniferous forests.

Copperhead snakes, like other pit vipers, are known for their heat-sensing pits situated between the eyes and nostrils on both sides of their head. These pits help them detect minute changes in temperature, enabling them to strike their prey with remarkable accuracy.

Key Identifiers of a Copperhead Snake

Body size and length

Copperhead snakes are medium-sized, measuring between 6-9 meters in length. They have thick, muscular bodies covered with ridged scales. Interestingly, females are generally longer than males, who, in contrast, have longer tails.

Information from Virtual Nature Trail at Penn State New Kingston page further reveals that female copperheads have longer lengths than males. The latter have longer tails.



The head of a Copperhead is somewhat arrow-shaped or triangular and can be distinguished from the neck. It has a unique ridge between the nostril and the eye on the top of its head. As Rick Curren from Scaly Adventures describes, its head color is “really coppery.”

Copperheads display a consistent color pattern. They have hourglass patterns alongside tan and brown markings. Newly born juveniles sport a greenish-yellow hue.


Copperheads possess vertical pupils, similar to a cat’s, and their irises are usually reddish-brown, tan, or orange. Young copperheads, on the other hand, tend to have more greyish eyes.

Eating Habits of Copperheads

Copperhead snakes are skilled ambush predators. Their diet includes mice, lizards, birds, and insects, which they swiftly attack and inject with venom. This venom damages the red blood cells of their prey, leading to oxygen deprivation and ultimately death.

Juvenile Copperheads primarily feed on insects like caterpillars, using their yellow-green tails to attract and capture their prey.

Behavioral Traits

Copperheads are known to bite when threatened, particularly when disturbed during their relaxation or hunting periods. They exhibit a characteristic behavior of rapidly vibrating their tails while releasing a strong smell when alarmed.

These snakes are often spotted during warm, humid nights post-rainfall. They are usually active during the daytime in spring and fall, becoming primarily nocturnal in the summer. Although they mostly reside on the ground, Copperheads can climb bushes and trees in search of prey.

They’re also adept swimmers and are known to bask in the sun. Their primary defense mechanism is camouflage.

Identifying a Copperhead Snake: Key Features

To swiftly identify a Copperhead snake, look for these distinguishing features:

  1. A triangular and plain copper-colored head without any markings.
  2. The presence of hourglass markings on its body.

Essential Tips

If you happen to cross paths with a Copperhead, it’s best to leave it undisturbed. They are known to become aggressive when agitated, and their bite, though not usually fatal, can cause considerable pain.

It’s especially advisable to steer clear of these snakes during their mating season when heightened hormonal activity can make them even more aggressive.

Copperhead Snake Reproduction and Development

Both male and female Copperheads reach sexual maturity at about four years when they’re typically around two feet long. The mating seasons fall between February and May, and then again from August to October.

The duration of their mating can vary from 3.5 hours to 8.5 hours, depending on the female’s receptiveness.

The Copperhead Bite: What to Expect

Copperhead snakes are known to strike without warning when they feel threatened. Their venom causes temporary damage to the affected area. While not typically lethal to humans, the venom can cause significant pain, and medical attention should be sought promptly, especially when children, older people, or immune-compromised individuals are bitten.
