We have a wilderness property in northern Ontario where we take our trailer, with a good population of bears. Near the end of the summer they often stroll through the clearing and take a look at us. At that time of year they are looking for blueberries and will sometimes chew up a hummingbird feeder to get at the sweet nectar. We do not put out a hummingbird feeder. Just clean up the bar-b after using it and we have never had a problem. Often go out in the morning and see bear scat in the yard left overnight.
