I see black bears in Canada quite often. These are not Grizzly bears like in Alaska. Grizzly bears are more aggressive because they evolved on the planes where they don't have trees to climb so are more defensive. Black bears on the other hand will retreat up a tree or where ever to get out of your way. We have never had a problem with them because we don't put our edible trash anywhere they can get to. We are careful with this and the bears go about their business as if we weren't there.
This guy is turning over rocks to get the little critters under them. Some of the rocks are pretty large but the bears are very strong for this sort of thing. There are more bears on the shoreline than ever before because there are fewer people to bother them now.
Higher up on the shoreline the black bears eat the spring grasses and sometimes lay around in the sun. Like I said we hike around them and don't have problem with them be aggressive. We do the regular stuff like make noise and surprize them and take special care of moms and babies not to disturb them.
