It is very common for bears to eat berries as it is what they use to stock up for the winter when going into a state of hibernation. Bears tend to eat blueberries, mulberries, raspberries, and boysenberries. Bears are omnivorous animals which mean that they eat meat as well as plants that have berries on them.
You will find that bears also commonly eat trail mix along with insects, fish, and money. These animals have also been known to eat elk and deer along with various small mammals.
Although which foods bears eat varies depending on the individual animal, it is certainly not uncommon for them to eat different types of wild berries, including blueberries.
