I think they are classified as preditors most places. And I've never seen one take down any animal but I'm sure they do, to many people reported seeing it. Then again, how many of those "I saw it" reports are people that found a black eating an animal it found dead? A 200# or 300# bear is not much of a match against a 600#+ angry moose or elk mother.
I wonder just how many of the animals they take out are sickly or injured tho? I sure don't have an answer. Yet if blacks are as dangerious as reported or believed, why aren't there more attacks on humans? I believe that the biggest danger of most blacks is their ability to beat you up and eat you. The Washington, Oregon and California coast range is full of them, so is western Montana and Idaho. Yet we hear more reports of attacks by lions!
This is of course all just theory as I've just never run into a lot of them in the wild and those I did left faster than any animal I ever saw. And of course I can't denigh the report of their attacks, it was a black that got Cynthia Bacon. An old hungry black that just wanted a meal and wasn't choosy where it came from. They have a tremendious potentional for danger, just like a buck deer, but in my experience always seem to aviod it. The big difference between the bear and the deer is that after the attack, the bear will probably eat you!
I think that another big myth about them revolves around the "I was attacked" storys. Most are bull. If a black attacks, you can't run away from it, it'll catch you and you can't climb a tree, it'll go up and beat you up up there and if you fight back and survive, your gonna have some pretty bad bruses to show. Most people reporting attacks by most wild animals, I don't believe were attacked but rather were standing in the escape route and got run over! Doesn't say much for their vision does it?
