Eight Interesting Facts About Grizzly Bears
Here are eight interesting facts about grizzly bears:
- “Prizzly bears” and “groler bears” are the result of the hybridization between polar bears and grizzly bears.
- Grizzly bears have a prominent hump on their back, which is actually a large muscle.
- While commonly believed to hibernate, bears actually enter a state of torpor, reducing their activity and metabolic rate.
- Grizzly bears’ diets can be impacted by climate change, affecting the availability of their preferred food sources.
- In addition to their varied diets, grizzly bears are known to have a particular affinity for moths.
- The hybridization of grizzly bears and polar bears is likely to increase as the Arctic sea ice continues to melt due to climate change.
- Grizzly bears have a keen sense of smell that is estimated to be 2,100 times stronger than humans.

Do Grizzly Bears Hibernate?
Grizzly bears undergo three distinct stages throughout the year, beginning with a period of normal activity during the spring and summer months.
As autumn arrives, they enter into a phase of hyperphagia, where they consume large quantities of food in order to gain weight for the impending winter.
Hibernation is the third stage, which can last between 4-7 months and is triggered by a combination of factors including a shortage of food due to seasonal changes, dropping temperatures, and snow coverage.
Where Do Grizzly Bears Live?
Grizzly bears can still be found in western Canada, Alaska, Wyoming, Montana, Idaho, and even southern Colorado. Traditionally, they were found from Alaska to Mexico and from the Pacific to the Mississippi, but the western expansion drastically cut down on their population.
In the northern Rocky Mountains, encompassing the Yellowstone and Glacier National Parks, as well as in western Montana and far northern Idaho adjacent to Canada, populations have persisted. In Alaska and northern Canada, grizzly bears can be found in huge numbers living inland.
The remaining 26,000 grizzlies in Canada are spread across Alberta, the three territories, and British Columbia, where more than half of them are found. From low-lying coastal areas to high-elevation alpine regions, grizzly bears can be found.
