Do Bison Attack Humans? Understanding the Risks!

Do Bison Attack Humans? Bison can attack humans, especially when they feel threatened or are provoked by close proximity.

Bison, often referred to as American buffalo, are iconic symbols of the American West.

These magnificent creatures, with their towering size and distinctive appearance, draw visitors from around the world to observe them in their natural habitats, particularly in national parks such as Yellowstone and Grand Teton.

However, while they may seem docile from a distance, bison are wild animals with unpredictable behavior.

This blog post delves into whether bison attack humans, the reasons behind such attacks, real-life incidents, and how to ensure your safety when encountering these powerful animals.

What Are Bison?

Definition and Overview

Bison are North America’s largest land mammals and belong to the Bovidae family, the same family as domestic cattle. [Do Bison Attack Humans?]

They have massive bodies covered with shaggy, dark brown fur, a large shoulder hump, and a pair of curved horns that they use for defense and fighting.

Bison can weigh up to 2,000 pounds (900 kg) and can stand up to 6 feet (1.8 meters) tall at the shoulders.

Despite their size, they are surprisingly agile, capable of running up to 35 miles per hour (56 km/h) and jumping up to 6 feet (1.8 meters) vertically.

Habitat and Distribution

Historically, millions of bison roamed the Great Plains of North America, from Canada to Mexico. However, due to extensive hunting and habitat loss in the 19th century, their numbers dwindled to near extinction.

Today, conservation efforts have helped bison populations recover, and they are now commonly found in protected areas, such as Yellowstone National Park, which houses the largest free-roaming herd.

Other regions include the Wind Cave National Park, Badlands National Park, and private reserves. [Do Bison Attack Humans?]

Bison play a critical ecological role in these areas by grazing and shaping the landscape, promoting the growth of native plants, and providing a food source for predators and scavengers.

They are also culturally significant to many Native American tribes, symbolizing strength, resilience, and the sacred.

Bison Behavior

Bison are generally peaceful, grazing animals that spend much of their time feeding on grasses and sedges.

However, their behavior can change instantly if they feel threatened or cornered. Unlike predatory animals, bison do not have to rely on aggressive hunting behaviors, but they possess strong territorial instincts and a need to protect themselves and their young.

This makes them unpredictable, especially during the calving season or when bulls are in the rut (mating season).

During the rut, which typically occurs from July to September, male bison (bulls) can become particularly aggressive as they compete for dominance and the right to mate with females.

Bulls are known to engage in fierce battles, charging at each other with their massive heads and horns. [Do Bison Attack Humans?]

When humans enter their space during this period, they may mistakenly perceive them as a threat or competitor, leading to a potential attack.

Reasons for Bison Attacks

Several factors can lead to bison attacks on humans. Understanding these triggers can help visitors take necessary precautions:

1. Close Proximity: Bison have a flight zone, an area around them that they consider their safety buffer. If a human or vehicle enters this zone, the bison may react defensively, either by fleeing or charging.
2. Protecting Calves: During the spring and early summer, female bison (cows) are particularly protective of their calves. Even seemingly calm cows can become aggressive if they perceive a threat to their young.
3. Loud Noises or Sudden Movements: Bison can startle easily, especially if approached suddenly or surrounded by loud noises. These sudden disturbances can provoke a defensive or aggressive reaction.
4. Being Provoked: Ignorance or curiosity can lead some visitors to provoke bison by approaching too closely for photographs or trying to feed them, which can quickly turn dangerous.
5. Unfamiliar Scents and Items: Items like food, brightly colored clothing, or unfamiliar scents can attract bison’s attention. If they approach out of curiosity and feel threatened, they might attack.

Statistics on Bison Attacks

Bison-related injuries are more common than those involving other large animals in North American parks, such as bears or wolves. [Do Bison Attack Humans?]

In Yellowstone National Park, for example, bison have injured more people than any other animal, with an average of one or two incidents each year.

While the number may seem small, it is significant considering the potential severity of these encounters. Most attacks occur when people get too close, underestimating the animal’s strength and speed.

Types of Bison Attacks

Bison attacks usually involve charging at high speeds, goring with their horns, or trampling with their massive bodies.

Unlike predatory attacks, bison do not aim to kill but rather to neutralize the threat. However, their size, speed, and power mean that even a brief encounter can cause severe injuries, such as:

• Goring Injuries: Caused by the sharp horns of the bison, resulting in deep wounds, punctures, and internal injuries. [Do Bison Attack Humans?]
• Trampling Injuries: Result from being knocked down and trampled by a charging bison, leading to broken bones, concussions, or other life-threatening injuries.
• Throwing or Tossing: In some cases, bison have been known to toss people into the air with their horns, which can result in severe trauma from the fall.

Severity of Injuries

The injuries resulting from bison attacks can be severe and, in some cases, fatal. Victims often suffer broken bones, lacerations, internal injuries, and concussions.

Emergency medical care is usually required to treat these injuries, and recovery can be long and painful.

Comparison with Other Animal Attacks

Compared to other large mammals, such as bears or moose, bison attacks can be just as dangerous.

However, they differ in that bison are herbivores and do not attack to prey on humans. Instead, they attack to defend themselves, their territory, or their young.

While bear attacks often involve predatory behavior, bison attacks are generally defensive. [Do Bison Attack Humans?]

This difference is crucial for understanding how to prevent and respond to encounters with these animals.

Real-Life Incidents of Bison Attacks

Numerous real-life incidents illustrate the potential danger of bison encounters:

• Incident at Yellowstone in 2015: A 43-year-old woman was gored by a bison while trying to take a selfie too close to the animal. She suffered serious injuries but survived. This incident highlights the dangers of getting too close for photographs.
• Incident at Custer State Park in 2020: A biker in South Dakota was thrown from her motorcycle after a bison charged at her. She suffered injuries but survived. The incident was caused by the biker inadvertently getting too close to a herd.
• Incident in 2021: A 9-year-old girl was tossed into the air by a bison in Yellowstone National Park after a group of visitors approached the animal too closely. Fortunately, she survived with minor injuries, but the incident serves as a stark reminder of the need for caution around wildlife.

How to Avoid Bison Attacks?

Keep a Safe Distance

The National Park Service advises visitors to stay at least 25 yards (about 23 meters) away from bison at all times.

This distance allows the animals to feel secure and reduces the likelihood of them perceiving humans as a threat. [Do Bison Attack Humans?]

In some cases, 50 yards may be more appropriate, especially if the bison are in large groups or with young calves.

Avoid Provocation

Provoking bison, intentionally or unintentionally, can lead to aggressive behavior. Do not approach them for selfies, try to feed them, or attempt to interact with them.

It is crucial to remember that bison are not domesticated animals, and any attempts to treat them as such can be dangerous.

Stay on Designated Paths

Staying on marked trails and paths helps ensure a safe distance from bison. These trails are often designed to provide safe viewing opportunities while keeping humans out of the animals’ immediate space. Venturing off the path can increase the likelihood of a surprise encounter.

Observe Bison Behavior

Understanding bison body language can help visitors identify when an animal is becoming agitated. Signs of agitation include pawing at the ground, snorting, flicking their tail, or lowering their head.

If you see these signs, it’s best to slowly back away and give the bison plenty of space to feel safe. [Do Bison Attack Humans?]

What to Do If a Bison Charges?

Remain Calm and Move Away Slowly

If a bison charges, the best response is to remain calm and not run. Running may trigger a chase response. Instead, back away slowly, maintaining eye contact without making sudden movements.

Use Natural Barriers

Use trees, rocks, or other large objects as barriers between yourself and the bison. These natural obstacles can provide a buffer and prevent the bison from reaching you directly. Bison are less likely to pursue a charge if a substantial barrier is in place.

Lie Flat if Knocked Down

If knocked down by a bison, lie flat on your stomach with your legs apart. Protect your head and neck with your arms. This position reduces the likelihood of further injury from trampling.

Final Verdict

Bison are one of North America’s most iconic and fascinating creatures, but they demand respect and caution from those who wish to observe them in the wild.

While bison do not typically seek out humans to attack, they can become highly dangerous if provoked, startled, or threatened. [Do Bison Attack Humans?]

By following safety guidelines, maintaining a safe distance, and understanding bison behavior, visitors can safely enjoy these majestic animals from afar.
