Where grizzly bear live and when it sleeps?

Grizzly bears primarily inhabit North America, particularly in regions such as Alaska, western Canada, and parts of the contiguous United States, including areas in Montana, Wyoming, and Washington. They typically prefer forests, mountains, and tundra environments. Grizzly bears are known to hibernate during the winter months, usually from late fall to early spring, during which they sleep in dens and do not eat, drink, or excrete. Their hibernation period can last from several weeks to several months, depending on environmental conditions and food availability.
