Brown Bears, also known as grizzly bears in North America, are large bears with a powerful build and a characteristic hump of muscle over their shoulders. Renowned for their strength and adaptability, Brown Bears are solitary yet highly intelligent creatures, capable of problem-solving and displaying complex behaviours.

Their fur, ranging from dark brown to light tips, provides camouflage in their diverse habitats. Brown Bears inhabit forests, mountains, tundra, and coastal areas across North America, Europe, and Asia.

Adult Brown Bears can weigh between 100 and 700 kilograms (220 to 1,540 pounds) depending on the subspecies and food availability. Brown Bears are omnivores, feeding on a varied diet that includes berries, roots, insects, fish, and mammals. During the summer and fall, they consume vast amounts of food to build fat reserves for hibernation. Mothers give birth to 1-4 cubs during winter. Newborn cubs weigh only around 350 to 600 grams (12 to 21 ounces). Mothers nurture their cubs for about two years. Cubs grow rapidly and reach their adult size between 5 and 10 years of age.
