Amur Tigers

Code:

Name me another extant apex predator that deliberately (and regularly) hunts and kills another large and dangerous terrestrial carnivore of similar-size, like tigers hunt bears?

Besides the tiger, name me another extant predator that also habitually hunts and kills another large, powerful similar-sized terrestrial carnivore?

None. However, a male brown bear is certainly capable of killing a similar size land semi predator, another bear:

Golden eagles also hunt red foxes and coyotes occassionally and martial eagles do kill jackals.

Code:

Here's the big difference though, tigers, especially in summer and autumn, actively prey on brown bears, and as scientific literature reports (and has documented), adult bears are taken frequently by male tigers. Do golden eagles prey on Eurasian black vultures like tigers hunt and kill brown bears??  We also don't know the relationship between the Barbary lion and Atlas bear, for all we know the lions could have dominated the Atlas bears. But we'll never know, so no point of using that example.

My question was why is the tiger, and not the brown bear, called "Lord, king, owner of the Ussuri taiga and Manchurian taiga by all the natives and experts, biologists?  I'm not talking about tigers being called apex predators, its common knowledge that tigers are the apex predators throughout their entire range in the wild since the Pleistocene. But why is the tiger widely regarded as the 'Lord' and supreme ruler of the taiga, even though they co-exist with one of the largest subspecies of brown bears on earth??

Because the tiger being a full time predator is rank as predator over the brown bear and also hunts them (mainly subadults, young adults and adult females). It does not make sense the call an omnivore an apex predator especially when it is in a similar region as a huge full time carnivore. Golden eagles do not prey on Eurasian black vultures, however, there are records of black eagles killing chicks of griffon vultures (although adult griffons are capable of repelling black eagles which have to gang up in pairs to snag a chick - Vultures of Africa by Peter Mundy) and occasionally kill adults (Scottwolverine1111 posted that accounts). One animal seems to be called a predator over another animal even if the largest of its kind is avoided or generally avoided.

By the way, here is another translation:

Translation:-

User:-"Is an adult male brown bear stronger than an adult male tiger? Tigers prey on them. So i am wondering....?"

Amurtigercentre:-"Hello! It depends that on which male bear and on which male tiger. But a tiger has once been seen eating an adult male they prefer to disperse as no one wants injuries."

User:-"Well, do tiger generally prey on adult male brown bears? And do they kill bears on regular basis?"

Amurtigercentre:-"No, we are not aware of such cases. On regular basis- definetly not, on himalyan-yes."

Just out of curiosity: which bear do you think will beat a Siberian tiger in a fight to death more often than not? Only the larger male brown bear and a polar bear will be able to beat a Siberian tiger, Bengal tiger, and African lion in my opinion, the other bears are too small. (A little off topic: While polar bears are less aggressive than grizzlies, they become aggressive during mating season and the older males will stand their ground - video and account posted on the polar bear thread. While there are accounts of grizzlies killing subadults, no record of mature male polar bears being killed. Ursus Artos posted an account on old carnivora that young males prefer to mate with younger females. Therefore grizzlies probably give mature male polar bears a wide breath during mating season but go for the young but not full grown sexually mature ones). The only other bear that can win might be the exceptionally large American black bear at 600 pounds and above.

Also in addition to the account of tigers depressing the population of black bears and brown bears in China due to predation, it seems that female brown bears choose to give birth to cubs in an area where there is a lack of tiger presence. Male brown bears also prefer to be in an area with an abundance of females:

Code:

Hence, males dispersing west from the population core may prefer to settle in the periphery where competition is low and sheep are available, but relatively close to the core areas where they can get access to females during the mating season (H7).
