Bear on the Prowl<br />

The black bear felt hungry. He sniffed the<br />

morning air. Food smells were coming from a<br />

campsite at the edge of the forest. The bear<br />

began to stride toward the tempting smell.<br />

A locked cooler full of food sat on the ground.<br />

But the bear strained for only a moment to open it.<br />

One swipe with his massive paw, and the top<br />

popped right off. The bear began to eat.<br />

Suddenly, two hikers walked into their<br />

campsite. Lunging at them, the bear also let out<br />

a deep growl. The hikers wheeled around and<br />

ran away.<br />

<strong>Bears</strong> will eat berries, leaves, fish, honey, and other<br />

things they can find in the woods.<br />

<strong>Bears</strong> raid campsites for food.<br />

But then the scared hikers stopped running<br />

and froze. The bear stopped, too. The bear did not<br />

want to hurt the hikers. He just wanted to scare<br />

them away from his food. Then the bear went back<br />

to finish his meal.<br />

When a black bear runs towards a person and<br />

stops short, it is called a bluff charge. That means<br />

the bear does not want a fight. It wants to be left<br />

alone. But people often do not know this. They are<br />

picturing bears as a bigger danger than they really<br />

are. The result is a dangerous situation for both<br />

people and bears.<br />

Getting close to a bear in the wild makes most<br />

people frantic with fear. There are good reasons.<br />

<strong>Bears</strong> can easily hurt or kill a person. But black<br />

bear attacks are rare. In fact, most black bears are<br />

afraid of people. When they see a person, they<br />

usually run away.<br />

But sometimes bears do attack people.<br />

Usually attacks happen because people do not<br />

know how to behave in bear country. And<br />

frightened people sometimes kill bears. So it’s<br />

smart to learn more about these animals.<br />

<strong>Bears</strong> are attracted to food left at campsites.<br />

Getting to Know <strong>Black</strong> <strong>Bears</strong><br />

<strong>Black</strong> bears are the smallest bears in North<br />

America. They usually weigh about 150 to 500<br />

pounds. Grizzly bears and polar bears are much<br />

bigger. They can be as much as 1,500 pounds.<br />

Thousands of years ago, even larger animals<br />

lived on Earth. There were short-faced bears,<br />

saber-toothed cats, and others. <strong>Black</strong> bears were<br />

too small to fight these big animals.<br />

Many of these large animals lived on the<br />

grassy plains. So black bears stayed in the woods.<br />

Curved claws helped them climb trees to escape<br />

danger. <strong>Black</strong> bears learned to eat plant foods since<br />

larger animals took most of the prey. Because of<br />

this history, black bears are still shy today. They<br />

would rather run away from danger than fight.<br />

5


<strong>Black</strong> bears still live in forests. Cubs, or baby<br />

bears, romp on the forest floor while their mother<br />

looks for food. Cubs learn to climb trees very early.<br />

They are safe there among the branches.<br />

<strong>Black</strong> bears can be found from Canada<br />

to northern Mexico. They live in dozens of<br />

northern states.<br />

On the East Coast, most black bears are<br />

actually black. Farther west, some black bears<br />

are brown, cinnamon colored, white, or even<br />

bluish gray.<br />

<strong>Black</strong> bears with<br />

white fur are<br />

sometimes called<br />

spirit bears.<br />

6


Beekeepers use wire fences to keep bears away.<br />

<strong>Black</strong> bears have a good sense of smell. This<br />

helps them find food in the forest. Some favorites<br />

are nuts, berries, roots, and grasses.<br />

Another common food for black bears is insects.<br />

<strong>Bears</strong> often break open rotten logs to find the tasty<br />

grubs inside. When bears raid a beehive, they gobble<br />

down the honey. But bears also eat the bees.<br />

When they can get it, black bears eat meat and<br />

fish. <strong>Black</strong> bears will eat almost anything.<br />

7


In the fall, bears will walk for miles to find as<br />

much food as possible. At this time of year, a bear<br />

may eat 20,000 calories every day. That’s about as<br />

much as 42 hamburgers!<br />

All that food turns into a thick layer of fat.<br />

During the winter, the bear lives off the fat. The<br />

bear crawls into a den to sleep. In very cold places,<br />

the bear may stay in its den without eating or<br />

drinking for seven months.<br />

Most of a black bear’s food comes from plants.<br />

8


<strong>Bears</strong> and People<br />

<strong>Bears</strong> eat all kinds of food. Unfortunately,<br />

that includes the foods people eat. When bears<br />

get used to getting food from people, it means<br />

big trouble for the bears.<br />

People have hunted and killed bears for<br />

hundreds of years. Sometimes farmers kill bears<br />

that eat crops or kill farm animals. Other times,<br />

people hunt bears for sport or simply out of fear.<br />

Years ago, black bears were completely wiped<br />

out in many places.<br />

Today, more and more people have moved<br />

into bear country. People have built houses in<br />

the woods. Campers have shouldered backpacks<br />

full of food and hiked into the wilderness. <strong>Bears</strong><br />

quickly sniff out people’s garbage, pet food, and<br />

even birdfeeders. Once a bear sees people as a<br />

food source, it will return again and again.<br />

9


<strong>Bears</strong> search people’s rubbish for food.<br />

<strong>Bears</strong> that get food from people often lose their<br />

natural fear of humans. Instead of bounding away,<br />

they come looking for a meal. That is when a black<br />

bear becomes dangerous. It may break into cars,<br />

homes, or tents looking for food. Some bears start<br />

attacking people. Checking a bear’s violent<br />

behavior once it starts is very hard.<br />

<strong>Bears</strong> that attack people are often shot and<br />

killed. <strong>Bears</strong> that spend time near people also walk<br />

across roads. Cars occasionally hit them.<br />

10


It’s good to know what to do if you find<br />

yourself in bear country. How can you help keep<br />

black bears safe How can you keep yourself safe<br />

Here are some tips.<br />

• Leave them alone.<br />

• Don’t give them food.<br />

• Keep food and garbage in<br />

bear-proof containers.<br />

• Travel in groups.<br />

• Make noise to scare bears away.<br />

Today, park rangers teach families about bears<br />

before the families go camping in the woods.<br />

The Real Teddy Bear<br />

President Theodore “Teddy” Roosevelt<br />

loved the woods. He often went hunting. One<br />

day, Roosevelt saw a young black bear. Because<br />

the bear was so small, he refused to shoot it.<br />

Newspapers everywhere reported the story.<br />

Soon, a new toy was created. It was a little<br />

stuffed bear. It was named after the popular<br />

President. People loved the teddy bear and<br />

began to learn about real bears.<br />

Visitors go to Yellowstone National Park to see the bears.<br />

Don’t Feed the <strong>Bears</strong><br />

For many years, visitors to Yellowstone National<br />

Park loved to feed the black bears that lived there.<br />

Feeding the bears made a fun picture. <strong>Bears</strong> ate<br />

candy bars, chips, or whatever people fed them.<br />

But many people were hurt. <strong>Bears</strong> often bit or<br />

scratched. Some bears became violent “problem<br />

bears.” Hundreds of bears were either shipped to<br />

zoos or killed. Today, park bears are left alone to<br />

find their own natural foods.<br />

13


Good News<br />

The good news is that today black bears are<br />

doing well. Scientists say that there are 700,000<br />

or more black bears. Bear numbers are growing<br />

in many places.<br />

But people’s numbers are growing, too. We<br />

must protect land for black bears and learn how<br />

to live peacefully with them. These important<br />

animals need our help to stay safe.<br />

<strong>Black</strong> bears need lots of forestland to survive.<br />
