Characteristics of the Copperhead Snake

In the eastern parts of the US, the copperhead snake is the most common venomous snake. Their Latin name is Agkistrodon contortrix.

Copperhead snakes are known for their unique and easily identifiable patterns of alternating bands of dark and light colors. Their bodies are adorned with hourglass, dumbbell, or saddlebag-shaped crossbands, set against a lighter brown, tan, salmon, or pinkish background. The copperhead’s heads lack any patterns, except for a pair of tiny dark dots on top.

These snakes have muscular, thick bodies with keeled scales and vertical pupils similar to cats.

When young, copperheads have bright yellow-tipped tails that they wiggle to attract prey, although this coloration fades by the time they reach three years old. While copperheads can reach lengths of up to 40 inches (1.05 meters), they typically measure between 2 and 3 feet long, with a lifespan of around 18 years.

Copperhead snake sounds

Copperhead snakes produce various sounds, although they are not known for vocalizing as much as some other snake species. Instead, they rely more on their body language and behavior to communicate. Here are some common sounds and communication methods associated with copperhead snakes:

  1. Hissing: When a copperhead feels threatened or disturbed, it may emit a low-pitched hissing sound. This hiss serves as a warning to potential predators or intruders to back off and leave the snake alone. The hiss is produced by expelling air forcefully through the snake’s glottis, a structure located at the base of its mouth.

  2. Rattling Tail: Although not as prominent as the rattlesnake’s rattle, some copperheads may vibrate their tails rapidly against the ground or leaves when agitated. This tail vibration can create a sound similar to a faint rattle. However, this behavior is not as pronounced or as easily recognizable as the rattling of true rattlesnakes.

  3. Body Posturing: Copperhead snakes may also communicate through their body postures. When threatened, they may flatten their bodies and coil into an S-shaped defensive posture. This display serves as a warning to potential threats to stay away.

It’s essential to note that copperhead snakes, like most venomous snakes, would rather avoid confrontation than engage in aggressive behavior. They will generally only use these communication methods when they feel cornered or in danger.

Behavior and diet

Behavior and diet


Copperhead snakes are fascinating creatures with a unique set of behaviors that make them stand out from other snakes. These venomous snakes are known to be expert hunters, often laying motionless for extended periods, waiting patiently for their prey to cross their path. With their camouflaged bodies and sharp senses, Copperheads are truly masters of stealth.

When threatened, Copperheads exhibit a unique defense mechanism by vibrating their tails, creating a rattling sound similar to that of a rattlesnake. This behavior is intended to deter potential predators and is often a warning sign to stay away.

Despite their solitary hunting habits, Copperheads are known to be semi-social snakes, often sharing communal dens during the winter months. They can often be found returning to the same den year after year, forming a tight-knit community of snakes.


What do copperhead snakes eat? This carnivorous species feeds on a variety of prey including baby cottontails, swamp rabbits, rats, mice, birds, snakes, lizards, baby turtles, frogs, toads, and insects, particularly grasshoppers and cicadas.

These skillful hunters are known for their ability to ambush their prey, waiting patiently until an unsuspecting victim wanders into their striking range.

Their diet mainly consists of small rodents, such as mice and voles, but they also enjoy feasting on insects, frogs, lizards, and salamanders. Adult Copperheads prefer mice, but they won’t pass up the opportunity to snack on small birds, other snakes, amphibians, and insects, especially the delicious cicadas. They are nocturnal and primarily forage during the night.

It’s amazing how this species has adapted to survive and thrive in its natural environment by having such a diverse and varied diet.

Copperhead Snake Bite

Copperhead Snake picture

Usually Copperheads will not bite. However, if you get too close, it can and will bite you to defend itself. The copperhead was responsible for approximately 37 percent of all venomous snake bites in the U.S. in 2001 (Lavonas E.J. et al., 2004)1, and most bites from the copperhead snake are in the eastern parts of the U.S., where they are more abundant.


The venom from a copperhead snake bite is toxic, and bites are painful. Medical treatment may not be necessary, but I will recommend visiting a doctor anyway. However, bites are very seldom fatal, and in fact, it is one of the least venomous snakes in the USA. Most people bitten by copperheads do not get antivenin because it is not necessary.

It may, however, cause serious damage to your tissue and leave scars. Also, there is always a risk of catching secondary infection from bacteria in the snake’s mouth.

Therefore, there is no point in trying to handle them unless you have some formal training in doing so, regardless if it bites or not.

Behavior Prior to a Bite

When the copperhead is disturbed, it will shake its tail to warn intruders. Sometimes it strikes out after trespassers. If its fangs accidentally penetrate skin, it will probably only inject a smaller dose of venom. See it as a warning rather than an attack, but do not agitate it further. It is not aggressive, but it will bite if threatened.

Striking & Heat Sensitive Pits

Copperheads can strike at a distance of 1/3 to 1/2 of their own bodylength. Copperheads have alternating light and dark bands, as do many other snakes, but the darker bands in the copperhead are unique as they are wide at the bottom of the snake and narrow toward the back. They have heat sensitive pits between their eyes and nostrils that helpthem track down prey.

Aggressive if You Touch

Usually found in rocky areas near water, copperheads prefer rodents but do take frogs and insects when needed. As the guy in the video explains, the venom is not that dangerous, and most people manage without antivenom. Be aware, if you mess with them, they can be rather aggressive.


Copperheads live in many different types of habitats, but they prefer staying close to water and rocky areas. Its density in wooded or suburban areas also indicates that it is a generalist regarding habitat.

When a copperhead is afraid, it lies completely still. Therefore, you may often encounter many dead copperhead snakes on roads, where they are killed due to their habit of freezing.

In nature it is often an advantage to remain motionless and wait for a threat to pass by. Such evolutionary reminiscences are a disadvantage in traffic.

Life Cycle of Copperhead Snakes

Life Cycle of Copperhead Snakes

The life cycle of Copperhead snakes is a fascinating and intricate process! Breeding season usually occurs between the end of July and September, during which males compete for the attention of females with their vibrant colors and mating rituals. Once a female has chosen a mate, she will lay her eggs or give birth to live young, depending on the subspecies.

The female Copperhead gives birth to between 3-14 baby snakes, which are about 7-9 inches long and already have venom glands. The babies are born with a yellow or green-tipped tail that they use to lure prey. Copperhead mothers do not stick around to care for their young, leaving the babies to fend for themselves from the moment of birth.

After birth, the young Copperheads must quickly learn to hunt and avoid predators, as they are vulnerable to being eaten by larger animals such as birds, mammals, and other snakes. They also have to navigate the harsh winter months, where they overwinter in dens with other snake species such as rattlesnakes and rat snakes.

As they mature, Copperheads reach sexual maturity at around 2-3 years of age and can live up to 18 years in the wild. They continue the cycle of breeding and giving birth to young, ensuring the survival of their species for generations to come. It’s amazing how these skilled hunters have adapted and evolved to survive and thrive in their natural environment!

Conservation status and human interaction

Threats and dangers to Copperhead snakes

The amazing copperhead snake faces many threats and dangers in its natural habitat, from predators to human encroachment.

The majestic bird of prey, including owls and hawks, are the copperhead’s primary predators, swooping down from above to catch them by surprise. However, the danger doesn’t stop there; copperheads also have to contend with other creatures such as opossums, raccoons, and even other snakes that may prey upon them.

Sadly, the biggest threat to copperhead snakes comes from human activity. Habitat loss due to urbanization, farming, and logging is putting their populations at risk, and they are also at risk of being hit by cars while crossing roads.

Additionally, some humans fear copperheads and may kill them on sight, leading to unnecessary fatalities. It is important that we take steps to protect these beautiful snakes and ensure their continued survival in the wild.

Conservation efforts

Conservation efforts for Copperhead snakes are essential to preserving this species and maintaining a healthy ecosystem. Sadly, countless Copperheads and other snakes are killed each year while crossing roads during the breeding season or while traveling to and from den sites. This is where organizations like the Amphibian Foundation’s Copperhead Rescue & Advocacy Program step in to help.

Their mission is two-fold. First, they rescue Copperheads from beheadings and other horrible deaths that result from human encounters. It’s crucial to remember that most snake bites occur when someone is trying to kill the snake. Second, they educate people about the ecological value and significance of Copperheads, helping people get to know their neighborhood snakes in Atlanta. The foundation inspires people to live in harmony with wildlife, including snakes.

The foundation also engages people on the benefits of snakes in general for a healthy ecosystem. Often, the snake that was killed by someone who thought it was a Copperhead was not a Copperhead at all. By educating people about the different types of snakes in their area, the foundation can help prevent unnecessary harm to snakes and maintain a balance in the natural world.

Tips for safe interaction with Copperhead snakes

  1. Keep a safe distance: When you encounter a Copperhead, keep a safe distance and observe from a distance. Do not approach the snake or attempt to handle it.

  2. Wear protective clothing: If you’re planning to explore areas where Copperheads may be present, wear long pants, boots, and gloves to protect yourself from potential bites.

  3. Be aware of your surroundings: Be cautious when hiking, camping, or exploring in areas where Copperheads may be present. Be mindful of where you step and where you place your hands.

  4. Keep your pets on a leash: If you’re out walking your dog, keep them on a leash and avoid areas where snakes may be present.

  5. Educate yourself: Learn about the behavior and habitat of Copperheads to better understand how to interact safely with them. Remember, most snake bites occur when people try to kill or handle snakes.


Do copperheads have rattles?

No, copperhead snakes do not have rattles. Copperheads belong to the pit viper family, which includes rattlesnakes and cottonmouths, but they lack the characteristic rattles found in rattlesnakes. Instead, copperheads can be identified by their distinct coloration and pattern.

How fast is a copperhead snake?

Copperhead snakes can move at a speed of up to 2 to 3 miles per hour (3 to 5 kilometers per hour) when they feel threatened or are trying to escape from potential dangers. While this speed may not be considered fast compared to some other animals, it is generally sufficient for them to move away and seek cover when they feel threatened.

Are copperheads aggressive?

Copperheads are generally not aggressive snakes. They prefer to avoid confrontation and will only become defensive when they feel threatened or cornered. Like most snakes, they would rather retreat and hide than engage in aggressive behavior. However, if they feel threatened, they may hiss or strike as a defensive response. 

What do copperheads do for the environment?

The copperhead snake controls rodent, frog, and insect populations. This is crucial because unchecked populations can harm plants and other wildlife. Copperheads, which eat rodents, reduce tick-borne diseases like Lyme disease. These creatures indicate a healthy ecosystem. Their role in the food web is vital to environmental health.

Are copperhead snakes federally protected?

Despite their ecological significance, copperhead snakes are not federally protected. However, they are considered state-endangered in Iowa and Massachusetts, and have a NatureServe conservation ranking of G5-Secure and IUCN Red List category as Least Concern.

Is a copperhead deadlier than a rattlesnake?

Copperheads and rattlesnakes both have venomous bites that can be dangerous to humans, but the potency of their venom can vary depending on the species and other factors. While copperheads are not usually considered as deadly as rattlesnakes, it’s important to treat any snakebite seriously and seek medical attention as soon as possible. Remember, prevention is the best defense when it comes to avoiding snake bites!

In Conclude

The copperhead snake is an incredible species that plays a vital role in our ecosystem’s balance. Although they have potent venom, they only bite in self-defense. It’s essential to respect their boundaries and learn how to interact safely with them in their natural habitat. By understanding these fascinating creatures, we can gain a deeper appreciation for the intricate interconnectedness of the biosphere.
