It’s not rocket science figuring out what Bears eat. Black bears are omnivores, eating both plant and meat. They are day-active, opportunistic feeders. Roughly 90% of a bears' diet is made up of vegetation. Bears have the best sense of smell of any animal. A bear's sense of smell is 7 times better than a hound and 2,100 times better than a human's.
