Nocturnal Bear is a term used to describe the URSA, a species of bear found in North America and Eurasia. URSA is a genus of the family Ursidae, which includes eight species of bears, including the brown bear, black bear, and polar bear. Nocturnal Bears are active at night and sleep during the day, making them difficult to spot in the wild. They are omnivorous, meaning they eat both plants and animals, and their diet consists of fruits, nuts, roots, insects, and small mammals. Nocturnal Bears are solitary animals, living alone or in small family groups. They are also highly intelligent and have been known to use tools to help them find food.
