When bears emerge from hibernation, they will be very hungry. And if a female bear has a cub, beware. She will protect it from perceived danger. It is best not to surprise bears. Bears are found around the Great Lakes and they feed upon spring flowers, grasses, animals, fish and later in the season, berries. If camping, keep food where bears can't smell it or find it. They are omnivores. They have always been part of the Great Lakes ecosystems.
