Grizzlies, or grizzly bears, are large mammals found primarily in North America. They are known for their distinctive brown fur, powerful build, and impressive size, with adult males weighing between 400 to 800 pounds. Grizzlies inhabit diverse environments, including forests, mountains, and tundra, and are often found in national parks like Yellowstone and Glacier. These bears are omnivorous, feeding on a varied diet that includes berries, fish, and small mammals. Grizzlies play a crucial role in their ecosystems by helping to disperse seeds and maintain healthy habitats. They are also a symbol of wilderness and conservation efforts in North America.
