Björn, which means "bear" in Swedish, is a common name in Scandinavian cultures. Bears are large mammals known for their strength and size, with several species including the grizzly bear, polar bear, and black bear. They are typically found in forests, mountains, and tundra regions, depending on the species. Bears are omnivorous, meaning they eat both plants and animals. Their diet can include fruits, nuts, fish, and small mammals. They are known for their hibernation behavior, where they sleep for extended periods during winter months to conserve energy when food is scarce.
