Yes, black bears are dangerous even if they don’t mean to be. Bears spend most of their time looking for food or eating whatever food they find. If you happen upon their territory, they may feel threatened and try to attack.

There is a higher risk of being attacked by a bear if you reside in or near an area where bears frequently forage. As a part of their natural preparations, bears should be avoided by hikers, hunters, and anybody else who comes into bear territory. Also, be sure to keep pets away from these areas too.

Fatal Black Bear Attacks

There is generally an average of one fatal black bear attack every year in North America. Most attacks take place in more rural areas such as Canadian woods, Alaska, or national parks. Below is a number of fatal black bear attacks by year in North America since 2010:

  • 2021: 2 Fatal Attacks (Alberta, Colorado)
  • 2020: 3 Fatal Atacks (North Carolina, Saskatchewan, Ontario)

One hundred and seventy-five pounds is the average weight of an adult female black bear; four hundred pounds is the average weight of an adult male bear (also called a “boar”). Black bears stand between five and seven feet tall when erect and three to four feet tall while standing on all fours.

Are Black Bears Territorial?

Black Bear Population by State
Black bears are not territorial, as they do not typically frequent the same spot. They like to move or hunt and will travel anywhere there is food nearby.


Bears are not territorial, even if they are guarding a food source or a companion while they are present. They don’t patrol or protect a specific area from other bears. Bears have some personal space, although various animals will intrude on each other’s living area at various times.

If black bears know there is food nearby, they are more likely to return to the same spot daily. They do not, on the other hand, return to the same location unless there are compelling reasons to do so. They’ll move over their enormous areas in search of food and mates if you don’t give them a reason to stay in your region.

What Do Black Bears Eat?

Bears do not eat humans in general since humans are not their primary source of food. In part due to black bears’ proximity to larger population centers, they average about a fatal attack every year in North America. While they produce more fatalities than polar bears, polar bears are more aggressive but live in more remote areas. The bear that most commonly attacks humans is the brown bear, which is generally larger than black bears and has a smaller range that includes the western United States.

How Strong Is A Black Bear?

The black bear is a powerful animal with sharp teeth that can easily tear through flesh.


Bears are without a doubt among the most powerful animals on the earth, and they have long been both loved and feared. Due to their massive body, acute sense of smell, speed, and biting force, they are among the most powerful animals on the planet.

The biting strength of a black bear is 975 pounds per square inch, it can run up to thirty miles per hour, and its front claws are shorter, measuring less than 2 inches in length. The claws are more curled and pointed than those of a grizzly bear. The teeth of a black bear may effortlessly shred and tear flesh without any problem. An adult black bear tooth is on average about 2.5″ from top to bottom and 0.75″ wide in the middle.

Are Black Bears Very Aggressive?

Black bears are timid animals who want to be alone and are not aggressive unless they feel threatened.


Black bears are typically not aggressive and the fear that “all bears want to attack people,” is not a healthy or safe way of thinking. There needs to be a balance. Black bears are kind, timid animals for the most part but thinking they are cuddle and friendly and attempting to approach or agitate their habitat is not safe by any means.

How Do You Deal With A Black Bear Encounter?

If you happen upon a black bear, never approach or run away. Instead, make yourself look as large as possible and make loud noises to scare it away.

If you happen to encounter a black bear, face the bear straight from a standing position. Never approach or run away from him. By spreading your arms or wearing a coat, you can appear as large as possible. Yell, bash pots and pans, or use other noisemakers to create as much noise as possible. Most likely, this will startle the bear and it will take off.

What Are The Different Ways To Survive A Black Bear Attack?

If a bear does ever attack you, the best thing to do is play dead. Box the bear’s nose and eyes if it tries to bite you.

If you travel to a region where bear encounters are common, bear spray should always be carried. Keep the bear spray in a holster or front pocket because you’ll only have a few seconds to use it. Don’t tease or taunt the bear, don’t try to be stealthy, don’t flee or make any abrupt moves.

It is believed that if a bear gets close enough to make contact, the best thing is to drop to the ground and pretend to be dead. Box the bear’s snout or eyes if it claws at you or tries to bite you. Obviously, avoiding any bear interaction is the best and most recommended option, adults, or cubs.
