The brown bear is a large mammal found in various habitats, including forests, mountains, and tundras. They are known for their distinctive brown fur, which can vary in shade from light tan to dark brown. Brown bears are omnivorous, feeding on a diet that includes berries, nuts, fish, and small mammals. These bears are typically solitary animals, except for mothers with cubs or during mating season. They can weigh between 300 to 1,500 pounds and are known for their strength and agility. Brown bears hibernate during the winter months, relying on fat reserves accumulated during the warmer seasons.
