Brobear - defending bears with the truth since 2000 AD. This is where we are seeking news reports or scientific data from biologists concerning the 'Interspecific Relations' between tigers and brown bears. Only new material is wanted here, nothing predating the year 2022. __________________________________________________________________ Why do we have so much to say on the topic of bears and big cats? Because if we keep silent, school kids will not have access to the truth. The internet is filled with false information fabricated by big cat fanboys. Fake data and misleading information can be found even within the most highly respected forums. If no bear fan is willing to speak up with the real facts, then the false information would be all that school kids and curious adults will find on the internet.

*For the record: as of this year - 2022 - there has yet to be filed even one single confirmed account of a tiger ever killing an adult male brown bear. Nor has there ever been filed even one single confirmed account of a tiger ever killing any bear of any species which was as heavy or heavier than himself. It is very likely that no adult male brown bear has ever been killed by a tiger in the Russian taiga since sometime far back into the Pleistocene when the tiger and the brown bear were first getting introduced to each other. Even then, when the adult male brown bear was ambushed by a tiger, the tiger ended up being killed by his intended prey probably about nine out of every ten such attempts. After enough time had passed for the tiger to gain the knowledge of the bear's physical superiority deep into his DNA to be established into his subconscious mind as instinct, from this point on, the adult male brown bear has been removed from the tiger's prey list. *Fact: Bears do not hunt tigers. *Fact: Tigers prey on bears, but always choose bears smaller than themselves - Asiatic black bears, juvenile or adolescent brown bears, and adult female brown bears. *Note: Full-Grown male brown bear = 9+ years old. *Note: Only new material is wanted here, nothing predating the year 2022. ______________________________________________________________________________________

Zhao Yan is a ranger in the Hunchun Bureau of China's Northeast Tiger and Leopard National Park and has been working in conservation for twelve years. He says that the palm pads of male Amur tigers are typically from 10.5 to 13 cm wide. The largest palm pad width he has seen is 14.5 cm. That is from a giant male tiger! The huge male Amur tiger nicknamed "Beast" aka "The monster" tiger from the Khabarovsk territory in Far East Russia, who was famed for his immense size, had a huge palm pad width of 13.5 cm. But a male Amur tiger from Northeast China has a even larger palm pad width of 14.5 cm. Indicating that there are even bigger Amur tigers out there than the 'Beast'. *And then there is BIG

To add to this, an interior grizzly bear of at least 5y has an average front pad width of 14.74cm and an average rear pad width of 13.56cm.

Bear milk is the most nutrient-rich milk in the animal kingdom. unseating bengal tiger milk by a factor of 7.3x. Extraction from both animals is equally perilous. grizzlymilk.com/pages/buy-now

PROTECTION OF ENDANGERED SPECIES: SIBERIAN TIGER www.rgo.ru/en/projects/protection-endangered-species-siberian-tiger *In my own words. Protecting the big cats is a good thing, even for a bear enthusiast. Protecting the Amur tigers and leopards is a good example. When their environment is protected, this is also a wonderful thing for the moon bears and brown bears that also live there. Everyone who can afford to give really should. *Tigers of every subspecies is an umbrella species; meaning that if the tiger is protected, then every animal species within his protected area also receives protection.

When their environment is protected, this is also a wonderful thing for the moon bears and brown bears that also live there. Everyone who can afford to give really should. You are right. Bears and tigers do not share prey-predator relations since tigers normally avoid bears, as they do sloth bears, and very very rarely would prey on a female or young bear. So females and young bears basically roam freely just fearing the adult male brown bears. The manchurian region naturally lack wolves which means the male bruins cannot have fresh meats for winter. The tiger fulfills the need of the wolves for bears, as tigers hunt prey and the broen beard usurp the kills. Which means that tigers benefit the adult male brown bears as wolves benefit grizzlies in the yellowstone park and lynx in the europe.

Reliable confirmed Amur tiger weights ( credits to Guate Gojira ) 1. 254 kg - ( 560 pounds ) Trans-Amur region. 2. 250 kg "evicerated" (could be c.270 kg "intact") - No location specified. 3. 249.5 kg - ( 550 pounds ) Bikin, Ussuri region. 4. 227 kg - ( 500 pounds ) North Kirin, Manchuria. 5. 224 kg - ( 494 pounds ) Manchuria. *Note: There are no confirmed 300 kg Amur tigers. 300 kg = 661.39 pounds. The largest male Amur tigers weigh below the 600-pound mark.

I scaled the log in the two pictures to the same length and this is the result; the biggest Ussuri brown bear I've seen so far assuming the tigress is an average adult individual. He could take out the tigress and her husband at the same time.

Here is a recent photo of a very large male Amur tiger and a typical male Ussuri brown bear. Both roughly the same size in terms of bipedal height or HB length. Of course the bear normally has a weight advantage of roughly 200 pounds.

Close-up. The tiger is an exceptional male Amur tiger. The bear is either an adult female or a young-adult male Ussuri brown bear ( from 5 to 7 yrs old ).

Reply to the post above: On average most female American black bears outweigh cougars whereas female Ussuri brown bears are a bit lighter than male Amur tigers in general and overlap with them in terms of weight.
Male Ussuri brown bears are similar in size and length as male Amur tigers, however, the former is heavier because of the thicker fur coat, fat, heavier bones. Stronger shoulder muscles allows a male brown bear to hit harder with their paw swipes although the Amur tiger has powerful paw swipes of its own (while not as powerful as the bear, it has agility on its side).
The weight difference between American black bear and cougar is much wider compared to the difference between the Ussuri brown bear and Siberian tiger.

A male American black bear is about two to three times heavier than an average male cougar while a male Ussuri brown bear is 1/3 heavier than a male Amur tiger. That is why the male American black bear has a 10/10 chance to beat a male cougar in my opinion while a male Ussuri brown bear has a 70% chance to beat a male Amur tiger in my opinion.
Note: Even a 30% chance of winning can make a stronger opponent show some respect (fear).

The size ratio between a Montana cougar and a Montana black bear, a leopard and a sloth bear, and an Amur tiger and an Ussuri brown bear are all three fairly even.
