According to Dave Fellows of the United States Geological Survey, a group of bears is called a sloth or a sleuth. Although bears are often considered loners, they can be quite social.
According to the Get Bear Smart Society, bears often live in close proximity to one another. They do not hunt cooperatively or live in large family groups like wolves, but it is not uncommon for unrelated adults to spend time together. Young adult bears are particularly likely to spend time in groups. Bears have a complex social structure and a strict dominance hierarchy. Older adult males are usually on the top, while young adults and cubs are on the bottom.
