Amur Tigers

[GreenGrolar]

Code:

Russian biologists, zoologists, naturalists and even local hunters know that some big male brown bears (400-600 kg) can outweigh even a big male tiger by several hundred pounds, in spite of this, most of the experts, as well as experienced hunters in the taiga, heavily favor the tiger to win a fight against a huge male brown bear. Why do you think that is?

And when both the tiger and bear are of similar-size (and equal size) and weight, the tiger will dominate the fights and almost always win. Why? because in history, there's never been a single reliable case ever, of a bear ever killing a similar-sized tiger in a fight to the death. Whenever the tiger and bear were of similar size, the tiger always kills and eats the bear. This is what history consistently shows. Bears need a size and weight advantage to stand a chance in a fight against a big cat, because the felids are just too armed, fast, agile and superior killers.

I guess this is the source you are referring too right? I believe it is talking about brown bears in general and the potential weight they can achieve. Tigers killing bears their own weight is impressive as pointed out. However, most brown bear subspecies seem to have a certain weight advantage over a Siberian tiger.

Larger males brown bears seem to be able to offer a decent resistance and it said the tiger is far from winning such fights very often yet it has more chance against a tigress and small tiger. Most wild animals prefer to hunt the weaker of their kind even if they have more than a 5/10 chance of killing the stronger one. 

Anyway the tiger is rank as dominant because it is an apex predator and will always have more kills even though it hunts mainly adult females. Although tigers do win at parity, most male brown bears subspecies seem to outweigh a tiger at average weights. I wish these accounts of tigers killing large bears will specify the gender.

Would the the bespectacled tiger killing a male brown bear be an exceptional case as a sloth bear killing a 12 year old Bengal tiger or equally unconfirmed?

I doubt any sloth bear can kill a tiger in a serious fight to death by the way although they have won some skirmishes.

I believe you posted this account on Carnivora which confirms what some of the biologists say. When it says a bear with every advantage probably refers to weight advantage, strength advantage, stronger jaws (if they outweigh a tiger by a decent size and weight advantage) etc (probably refers to larger male brown bears and polar bears at least). At equal weights most Ussuri brown bears are female.

Code:

Here's what Colonel Kesri Singh (Who had personal experience with tigers and lions) had to say about the tiger: "Some northern bears are larger, but they lack the tigers tremendous five-fold armament - to say nothing of his agility."

Tigers do have amazing five fold armaments (agility, better killing bite, stronger jaws pound to pound, sharper claws, explosive) and are way better hunters than even the larger and stronger polar bear which can kill belugas five times its weight (making them the best hunters out of all bears). Larger male polar bears also have stronger jaws overall than tigers and lions (although the tiger and lion has stronger jaws pound to pound) and can bite through beluga hide are quicker killers than brown bears though big cats are quicker killers. There are accounts which says a bear has stronger bones and being a plantigrade can hit harder and will have more strength in pushing and pulling even at equal weights but this might not be the thread to post these accounts. However, the tiger has greater agility, a better killing bite, and a way better hunter, and quicker killer probably balances this out. I acknowledge the tiger has strong bones of its own too. I will post more on morphology at the proper thread. 


Also I agree with you that where there are an equal number of tigers and brown bears, the largest cat will have more wild boar kills on its list. No brown bear can match a tiger when it comes to hunting skills. It is much easier to find tiger on wild boar prey than it is to find a brown bear on one.

Here is something interesting for Dale Miquelle:

Code:

"All i can say is, the Amur can be highly ferocious, and i would consider it more than unsafe to assume otherwise. In regard strengths (relative) The bigcats have reduced collarbones when compared to Ungulates and Bears, which increases flexibility and speed, while compromising ultimate strength potential, however, the Amur is least lacking, among Pantherines, in this department. Finally, the Amur should attain the greatest weight potentials under Bergmans rule but is now Challenged by the movement of Tigers into higher elevations due to the influence of man. Here we might get other Pantherine species facing similar increases in body size. I hope this is of some help."

I know it does not stop tigers from preying on adult bears and ungulates but brown bears do seem to have stronger bones (not saying tigers are weak as they are very powerful). The amur tiger seems to be the least lacking among pantherines might make it the strongest extant cat.

Because of the tiger's weaponary and killer instinct. Some biologist also favour leopards against gorilla. Yet there are accounts which say that the Siberian tiger will usually avoid a male Ussuri brown bear. From example, Alexander Batalov who said the bespectecled tiger killed Chamlid also said that tigers prefer to avoid male brown bears during mating season:

This is similar to the account above which says the tiger is far from winning fights very often against a large brown bear which can weigh 400, 500, and 600 kg yet it also says the same large brown bear has a better chance against a tigress and small tiger. Reply
