There is a world somewhere between reality and fiction. Although ignored by many, it is very real and so are those living in it. This forum is about the natural world. Here, wild animals will be heard and respected. The forum offers a glimpse into an unknown world as well as a room with a view on the present and the future. Anyone able to speak on behalf of those living in the emerald forest and the deep blue sea is invited to join.

I bet, that no tiger would drag this one anywhere, I think, that not even biggest bear there is would move this more than a meter :)
Honestly, I am 100% sure the largest bear can easily drag more than twice or thrice that weight with no sweat. There is a video on the "Bear Strength" where a polar bear was dragging a dead, bloody walrus, and that walrus appeared to be 2 to 3 times heavier than the bear.
I didn´t see video in bear strength thread, but you meant this?
Quite difficult to be sure about that walrus size, looked like to be a little bit bigger, than that bear, so maybe 500-800 kg walrus? For sure not even close to big ones weighing even 2000 kg, those giants make polar bears look pretty small :) But this video shows of course, that bear is strong, but also, that it takes some effort to kill and drag this size opponent.
Yes, that video. Harder to tell from a distance than up close, but the bear looks 400kg and the walrus at 800kg, still twice his weight. It is also actually really hard to drag on snow, since large amounts of weight condenses the snow and increases the coefficient of friction. The difference could make it so that the bear is dragging the walrus and an additional few pounds (or few hundred, I don't know).
Since it was dragging uphill, I think it was struggling moreso with its positioning relative to the walrus and tried to shift its weight back to gain greater leverage. If this was on flatter ground, it would be significantly easier, and to be honest, I don't think the bear would even be dragging near the max it can drag.
My estimate is from the videos I've analyzed, but a big cat should drag between 5-8 times its own weight with its own jaws before not being able to do so.
I believe 5-8 times, when I see it :) It is one thing to try and another to do it. I mean a tiger 200 kg dragging 1600 kg... I don´t believe before I see it. I am still waiting to see a 1000 kg in some footage. Most animals which I have seen have been maybe 500-600 kg max.
That polar bear looked to me be in quite close to size of that walrus, when on top of it. In different angle walrus looked bigger, but then again it had quite small tusks. My estimation is, that maybe 1,5 times heavier than that polar bear. Angle makes many things to look like bigger, but here we had these animals wrestling and at that moment that walrus didn´t look to be much bigger. But of course I can´t be sure.
Still that footage showed how hard work it is to fight with walrus and it didn´t give clear picture about it, that how long distance that bear might have dragged that walrus and how easily. I think, that many descriptions about bear strength too are exaggerated at least what comes to it, that how easily bear would drag something weighing 1000 kg or more. Some video footage for sure show, that a moose calf 200-300 kg is like a ragdoll with a bear and bear can "throw" a cow to ground with ease. But that doesn´t mean, that 1000 kg of dead meat is easy thing to move long distances. In every footage I have seen, when a predator is dragging something clearly bigger than itself (lions, tigers, bears etc.), it has been with effort, not just like that.
