Before I came to Cody, Wyoming; the first thing that always popped into my head about Yellowstone was Yogi Bear. For those who are unaware of the character, Yogi Bear was a cartoon grizzly bear from the 1960s. Yogi lived in a national park, called Jellystone, and was always causing trouble for the rangers as he tried to steal “pic-a-nic baskets.”
Now what does this have to do with Yellowstone? Well, Jellystone was based on Yellowstone, and Yogi Bear’s antics of trying to get human food was based on grizzly bear behaviors of eating human food.
The grizzly bear is one of the most sought-after animals in Yellowstone National Park by tourists. Visitors on many of my tours through the Draper Natural History Museum talk about how they hope to see a bear before they leave, specifically a grizzly. And I’m in the same boat. I am from California, an area once famed for their grizzly bears, but that now has barely any. So, I too hope to see one before my time is up.
Grizzly bears live in mountain meadow environments, but live throughout the Yellowstone area. They range in color from a light, golden brown to very dark, almost black. They differ from black bears, another bear species in Yellowstone, in a number of ways:
- Size: Grizzly bears are larger than black bears, with females weighing from 200 – 400 pounds, and males from 200 – 700 pounds.
- Hump: Grizzly bears have a large hump on their back that black bears do not have.
- Claw Size: Grizzly bears have larger and longer claws than black bears.
Grizzly bears eat a lot and will eat almost anything. They are omnivores, eating trout, elk, honey, nuts, whitebark pine, and berries. However, what they eat the most are moths. Grizzly bears eat up to 40,000 moths a day , in the fall when they prepare to hibernate.
The grizzly bear’s constant foraging began to cause problems in the park and the Greater Yellowstone area. They started eating human food that was either handed to them or stolen by them. As they began scrounging through garbage cans, Yellowstone Park put out a set of bleachers near a dumpsite so people could photograph and watch the animals forage .
From 1931 – 1969, there were 48 human injuries per year . By the 1970s, park rangers realized that they needed new bear management programs. This started the campaign, “a fed bear is a dead bear.” They began extensive education for visitors, to increase awareness of the consequences of giving “Yogi” a snack.
Grizzly bears are very smart animals, and if they discover an area that produces an abundance of easily-attainable food, then they will continue to haunt that area. So, the first thing that rangers sought to do was to eliminate what was attracting bears. They removed the bleachers and replaced all trash cans with ones that were hard for animals to open.
The rangers say that most bear and human conflicts could easily be solved if people would remove what attracts bears. Bears have an extremely keen sense of smell, and are able to trace a scent from more than 15 miles away . The most important thing to do is to make sure that you do not leave out any food and throw your garbage away in the bear-proof trash cans . You want to make sure that a bear is unable to find it and give it a taste.
The female mother bear and her cub in our exhibit in the Draper Natural History Museum have to do with this very subject. Our female, Bear 104, was hit by a car and killed, leaving her one-year-old cub, G86, alone. He began getting into conflicts with humans over food. Because he become used to people, they knew that if he kept following that behavior, he would eventually hurt someone. The only option left was to put him down, reuniting him with his mother.
