Yes they do. Many bears are expert climbers, and with their excellent sense of smell, finding a bee's nest is easy for them. Bears are omnivorous, which means they eat both meat and vegetation. They like eating other mammals, insects (even wasps, bees and termites, whose stings seem not to bother them), plants, nuts, fish, eggs, fruit, and people's picnics - if they can find them. They will also eat carrion (rotting meat) if necessary.
