Bears

Although they may engage in significant foraging at night, brown and American black bears are typically diurnal, which means that they spend the majority of their time awake during the day. While female sloth bears with cubs may consume more during the day to avoid competition from conspecifics and nocturnal predators, other species may be nocturnal, active at night. The majority of bears are solitary, and they are thought to be the most asocial Carnivora. Only moms with young or sporadic seasonal surpluses of tasty food cause bears to be seen in groups. Males can fight, and elderly people may have severe scarring, which shows that sustaining dominance might be quite difficult. Bears have a keen sense of smell and may find carcasses up to a few kilometers away. They utilize olfaction to find new meals, meet partners, stay away from rivals, and identify their pups.

Ever since the US government labeled otters an endangered species and began protecting them, their number has been growing. Due to its growth, it now faces competition from brown bears for clams. Brown bears, who are extremely adaptive, have started to hunt on sea otters as a result of this rivalry. Although many bears are willing to scavenge dead otters, others have grown to like fresh otter flesh over time.
