First, predators aren't very adept at following the rules we set for them. Bears share territory and wolves hang out where they're not supposed to. We recently saw tracks of three different grizzlies in one section of Canyon Creek Road. One of our neighbors has a video of four (yes, four, likely a mother and three grown siblings) mountain lions hunting together. We saw a pair of whitetail deer following a lynx around. What the heck were they thinking?
Speaking of following, predators like to follow people. We have been followed by bears on multiple occasions and have been followed by a wolf also. Trailing a human doesn't seem to be a stalking behavior, it seems to be more of a keeping tabs on a potential threat. Maybe they think that all humans are hunters, and we might leave a carcass behind. Maybe it's better to have a potential threat in front of you than behind you. Maybe predators are just plain curious about us. This following behavior leads to some hilarious and potentially dangerous situations. Last summer we encountered a family of four from out east on a remote trail in Glacier. As we started walking again, we saw a black bear up ahead on the trail a hundred yards or so behind the family. We wondered what the family would have thought if they had looked behind them and seen the bear following them! Out and back hikes pose another danger. Once we were coming back down from Demmer's Ridge when we surprised a large black bear who seemed confused by our change in direction. We ran into that darn bear twice more on the way down the ridge before he finally left the trail.
Finally, when is a predator really a predator? In Glacier, only 11% of a Grizzly's diet consists of meat. And that 11% is largely scavenged meat (theft from other animals, roadkill, and the like). Grizzly's don't really go on a hunt, per se, they seem to grab whatever is handy.
