Brown Bear

The brown bear is one of the largest land mammals and lives across Europe, Asia and parts of North America. It occupies a wide range of habitats, including forests, mountains, tundra and open meadows. Its thick fur varies from light brown to almost black depending on the population and the season. Brown bears are omnivores, meaning they eat both plants and animals.

Their diet changes throughout the year and may include berries, roots, grasses, insects, fish, small mammals and the carcasses of larger animals. Strong forelegs with long claws help them dig for food, turn over rocks, break apart rotten logs and catch fish during spawning seasons. Their excellent sense of smell allows them to detect food from several kilometers away, making it their most important sense.

Brown bears usually live alone except during the breeding season or when a mother is raising her cubs. In regions with cold winters, many spend several months in a den, where their body temperature drops only slightly while their heart rate and metabolism slow enough to conserve energy. During this period they do not eat or drink and survive on the fat they stored during the warmer months.

Cubs are born in the den during winter and remain with their mother for more than a year while learning how to find food and avoid danger. Although brown bear populations remain stable in some areas, others are threatened by habitat loss, conflicts with humans and illegal hunting, making conservation measures important in several parts of their range.
