Note how much the bear grapples and rips at the boar, rather than a tiger's quicker grapple and then throat bite. Interesting how killing style varies b/t big cat and bear.

One omnivore triumphs over another. As for the above analogy, makes sense since tigers are primarily carnivorous, while bears are still mostly adapted for an omnivorous diet.

My God, the power of that bear. I'd love to know if that was a predation or just scavenging.

^I think it was scavenging, that bison's body was really stiff and bears are rarely known to bring down adults.

Plus there were some (presumably) scavenging birds surrounding the carcass too. I doubt they'd stay so close if it were a living, violently thrashing adult bison.

You are both probably right. It was still a very impressive display of the bear's strength.

Is it just me, or does this bear remind anyone else of Arnold in the first Terminator movie going after Sarah Connor. Amazing but scary how single-minded this bear is.

^I wonder how fast bears really are. Obviously quickly since they can catch cervids, but probably not as fast as some factoids would suggest.

I recently posted a paper which tracked brown bears via GPS collars, which should be a pretty reliable means of estimating speed. Sometimes they fled from approaching people, and escape speed was up to 31 km/h. I can buy that being top speed. The videos I've seen of them catching ungulates either seem to involve some kind of terrain where the ungulate can't utilize its full speed to escape (e.g. a forest), or some other idiosyncrasy occurs (I've seen a video where a bear chases a sheep, but for some reason the sheep slows down at one point, enough so that the bear was able to catch up to and dispatch it). theworldofanimals.proboards.com/post/58746 |

It's the grizzly's endurance that impressed me the most in that video, more so than its considerable speed.

^ So somebody like Usain bolt might actually be able to outrun a bear, huh.

Over a short distance, probably yes. However I have a feeling the bear can maintain top speed or at least very high speed, far longer than even elite athletes. I wouldn't be surprised if the bear could maintain 18 to 19 miles per hour for well over a mile, which is beyond any human's capability. So if it's a short sprint, yes human sprinters can probably outrun a bear. But if it is longer than that the bear is going to catch him/her.
