Guys, check this out, you will definitely love this! At reply #53, Peter included the 8 year olds (which might not be fully grown) on his chart. The average for that is 568 lbs. But guess what i did? I made the calculations for the bears only 9 years old and up, check out the results for those 5 specimens:
240 kg 305 kg 268 kg 363 kg 256 kg
This equals to 1432 kg, divided by 5=
286.4 kg (631.40 lbs)

So there you go, that should be the new average weight for 9+ year old male Ussuri brown bears. 631.40 lbs.

Thank you for the sample, Kodiak; that's very clear information as you also have the specific age classes attached to it. It's like I expected, the difference in size between bears below 9y of age and above 9y of age is definitely there. Yes, those three 8 year old specimens were very small, 210 kg, 214.5 kg, 218.5 kg. If we take these three out (which is the correct thing to do), the difference is 28.9 kg (63.71 lbs).
If you agree with this, you shoud edit our "weight collection" thread with this new info

theundertaker45 : Now we can clearly see, without any more speculation, that the old Kucherenko table included 5+ year old specimens to get a 582 lb average weight (which really isn't a low average weight either). But now with this new data that was first posted by Warsaw, and then analyzed by Peter, we can really see the differnce between ages and why only the 9+ year olds should be included. So i dont think the Ussuri brown bears "got larger", we just didn't have this great detailed data.

Reply 61. There will always be giants and dwafts in every animal. Boldchamp posted a picture of at least three male lions and one full grown male was way smaller than the rest. I believe there will be giants and dwafts among the Ussuri brown bears too.

I believe there will be giants and dwafts among the Ussuri brown bears too. Yeah, but the thing is those 8 year old Ussuri brown bears were most likely not fully grown, that is why they were much smaller then the rest of the sample.
An 8 year old brown bear can be fully grown already, but to know this, the bear needs to be radio-collared at 8 years old and his weight monitored until at least 10, 11, or 12 years old, if his weight is steady, that means he had reached full size by 8. But if this info is not provided (which never is), than we treat the 8 year old brown bears as not fully grown.

Hey brobear, do you think the Ussuri brown bear is a grizzly bear or would you consider it a different subspecies?

Hey brobear , do you think the Ussuri brown bear is a grizzly bear or would you consider it a different subspecies? Classification is a thing that the greatest experts are rarely in total agreement on. The American grizzly and the Russian "black grizzly" are two separate subspecies. ( According to theory ), The American grizzly is the product of Ussuri brown bears crossing over the Beringia land bridge from Siberia into Alaska. After a couple of hundred-thousand years of separation, they became two subspecies. So, biologically, the Ussuri brown bear is a grizzly. Classification wise - NOT.

But that's captivity. Tigers are extinct in the wild in South Korea.

If i was ever a head of wild animals constitution so i would make these rules:-
1. No animal should be killed without reason.
2. Hunting for fun and sport banned.
3. Anyone who would be caught hunting illegically would be jailed and fined.
4. Some impressive specimens like of exceptional huge size should not be killed but should be tranquilized, tested and released again.
5. Every animal kept in zoos should have a limited time according to age and then again should be released in wild. For example, a bear of 25 year should be kept only 5 year in captivity and spend his remaining 20 years in wild.

By Manipura Puma: 10 Impressive Feats and Facts Of The Ussuri Brown Bear! So I don't start to take this Vs battle too seriously, I've done a 'factsheet,' to make comparison's with the one I did for the Tiger and an 'Impressive Feats' section for the Bear too, as promised, so here are the 'Bear facts.' All info is taken from the links at the bottom of the post.(P.S. I don't know that much about Tigers and even less about Bears so the "Feats" bit is not limited to just Ussuri Brown Bears but Brown Bears in general. And I'm confident that it will make everybody's day and lives just that little bit more complete! : ) Ussuri Brown Bear AKA The Black Grizzly (ursus arctos lasiotus) Gray 1867 Size, Description + Appearance Large and round head with a protruding snout, very close to the Kamchatka Brown Bear. Though it has a more elongated skull, a less elevated forehead, longer nasal bones and less separated zygomatic arches. It is also somewhat darker in color, with some individuals being completely black. They also have a large hump of muscle over their shoulders which along with their powerful forearms, back paws and claws, can enable them to climb tree's, as well as reach surprisingly fast speeds. Head/Body Length: Males 252cm / 8.3feet / (3.2metres) Possibly up to 10 feet? (Like Kodiak Bear) Females 230cm / 7.6feet / (2.3metres) Weight: (Maximum weight is in the fall) Females 100-300kg Males 200-600kg (Kamchatka 685 kg) Skull and Claw Size Adult males have skulls measuring 38.7 cm(15.2 in) long with a range of between 31.5cm(12.4 inch) and 45.5cm(17.9 inch) while female skull length has a range of 27.5cm(10.8 inch) to 39.7cm(15.6 inch.) Width of the zygomatic arches in males is 23.5cm (9.3 in) wide with a range of 17.5cm(6.9 inch) to 27.7cm(11 inch) and 14.7cm(5.8 inch) to 24.7cm(9.7 inches) for females! Chest girth and Zygomatic width of the cheekbones is closely correlated to weight. Wide cheekbones give the Bear a very powerful bite and ability to leave deep puncture marks. Especially with the greater size and weight of such Bears. Claws are 5/6cm(1.9-2.3inch) or 7/10cm(2.7-3.9inch) when measured along the curve and are capable of delivering deep lacerations. Range The Ussuri Brown bears are found in the Amur and Ussuri River regions of the Russian Far East, northeastern China, the Korean Peninsula and Japan. 10 Impressive Feats And Surprising Facts Of The Brown Bear. 1) Some recent 2017 studies from Scandinavia and Yellowstone, USA. Show that contrary to popular belief, Wolves do not hunt more often when they share a range with Brown Bears to compensate for prey which is scavenged or taken ownership of by the Bears. Meaning that Brown Bears may have a more negative effect on Wolf health, fitness and even distribution than what was previously thought! 2) Brown Bears are the fastest subspecies of Bears. They've been clocked going at 35mp/h (63km/h) and could possibly even reach speeds of up to 40mp/h as so little study has been done to measure the Brown Bears speed. 3) Although Omnivores, where there's sufficient prey, Brown Bear's kill far more often than what was previously thought. As this study where collared videos were attached to Brown Bears by wildlife biologist Chris Brockman in Alaska, shows: "Bears had previously been thought to kill as little as one calf every nine days. It turns out that, on average, they kill about one a day. One bear managed 44 calf kills in just 25 days. On average 6.3% of their day was spent feeding, they took down calves, hares, and, in one case, another bear. More than 60% of their time was spent resting. Another 23% was spent in transit. Several interesting pieces of footage revealed what the bears ate, including a swan, ptarmigan eggs, and other bears. The most surprising footage was a 10-year-old male brown bear killing and eating a six-year-old female brown bear." This portrait of a predator which kills 2 times a day or more is far different to the lazy, slumbering image many people have of Bears from the Zoo! 4) Ussuri Brown Bears are so adaptable as to be able to get sustenance and possible therapeutic benefits from many tree's including cone's of the Korean Pine and the sap of 3 different species of Birch tree in Russia(White, Yellow + Rockbirch) (Bromlei 1965) 5) Brown Bears can eat up to 90lbs of meat a day when preparing for hibernation. 6) The molar teeth of the brown bear increase in size as they go further in the mouth and the brown bear predominantly uses its largest molars to grind up tough food. 7) The bear kills its prey by biting it in the neck or back. It can also kill the prey animal with a strike of its forepaw, which is often enough to break the animal's spine. Often the bear will also bite its prey in the snout, which leaves deep canine marks that are clearly visible. The distance between the bear's canines is between 45–65 millimetres. The bear has also been known to bite its prey in the back of the neck to kill it. 8) A Russian Brown Bear can turn over rocks weighing over 500kg. 9) The trail of a Bear which is not settled in hibernation and which is tracking other predators such as Tigers and Lynxes, in order to capture their prey, can be 22% of the total length of the Bear's trail. (44km out of 200km.) 10) The Ussuri Brown Bear can sometimes even reach greater sizes and dimensions than their Kamchatka counterparts: The largest skull measured by Sergej Ognew(1931) was only slightly smaller than that of the largest Kodiak brown bear! When you add in that Brown Bears have been known to challenge the Amur Tiger over kill disputes and have even killed Tigers, including 2 young adult males, and that the most often preyed upon ungulates by the Ussuri Brown Bear is the Wild Boar and Red Deer(Bromlei) and that the Kodiak Bear(ursus arctos middendorffi) is often touted as the largest terrestrial carnivore on the planet(National Geographic) and also consider that Brown Bears have been known to hunt Bison, Moose and Black Bears, then despite often been classed as or seen as an Omnivore, the Brown Bear is also an impressive predator in it's own right, when it needs to be! royalsocietypublishing.org/doi/10.1098/rspb.2016.2368 www.bearconservation.org.uk/ussuri-or-amur-brown-bear/ www.treehugger.com/how-fast-can-a-bear-run-5113356

Reply #76 - 8) A Russian Brown Bear can turn over rocks weighing over 500kg. ( 1,102.31 pounds ). *Actually, the post by Manipura Puma states 50kg which I instantly recognized as being a typo. In fact, Casey Anderson's grizzly named Brutus easily overturned a rock weighing 2,000 pounds ( 1 ton ) to get to some fish hidden underneath.

en.wikipedia.org/wiki/Ussuri Ussuri. The Ussuri or Wusuli (Russian: Уссури; Chinese: 乌苏里江; pinyin: Wūsūlǐ Jiāng) runs through Khabarovsk and Primorsky Krais, Russia and the southeast region of Northeast China. It rises in the Sikhote-Alin mountain range, flowing north and forming part of the Sino-Russian border (which is based on the Sino-Russian Convention of Peking of 1860), until it joins the Amur as a tributary to it near Khabarovsk. It is approximately 897 kilometers (557 mi) long. The Ussuri drains the Ussuri basin, which covers 193,000 square kilometers (75,000 sq mi).[1] Its waters come from rain (60%), snow (30–35%), and subterranean springs. The average discharge is 1,150 cubic metres per second (41,000 cu ft/s), and the average elevation is 1,682 metres (5,518 ft). The Ussuri has been known by many names. In Manchu, it was called the Usuri Ula or Dobi Bira (River of Foxes) and in Mongolian the Üssüri Müren. The Ussuri has a reputation for catastrophic floods. It freezes up in November and stays under the ice until April. The river teems with different kinds of fish: grayling, sturgeon, humpback salmon (gorbusha), chum salmon (keta), and others.

www.bearconservation.org.uk/ussuri-or-amur-brown-bear/ Accepted scientific name: Ursus arctos lasiotus (Gray, 1867). Description: Similar to the Kamchatka brown bear (Ursus arctos beringianus) but generally darker in colour with a more elongated skull and less elevated forehead. Males can be up to twice the size of females ranging in weight from around 200 to 600 kg. Range: Heilongjiang Province and the Amur Oblast, Northeast China; five isolated regional populations on Hokkaido, Japan; Ussuri and Amur river region south of the Stanovoy Mountains, Russia (borders with China); Sakhalin Island and Kunashiri, Etorofu and Iturup Islands in the Kuril Islands chain, Russia (immediately north of Hokkaido) and the Shantar Islands, Russia. Some authorities believe that the bears found on Hokkaido and on Kunashiri and Etorofu Island in the Kuril chain are a separate subspecies, the Hokkaido Brown Bear, (Ursus arctos yesoensis). Habitat: Forests, mountainous regions and coastal areas. Status: Overall Ursus arctos is classified as of least concern by the IUCN but most if not all of the Ussuri subspecies seem vulnerable and in decline. Only a few bears remain in North Korea where they are listed as a National Monument and protected. About 500 to 1,500 are present in Heilongjiang and are classed as a vulnerable species. On Hokkaido the small western Ishikari subpopulation is listed as an endangered species in Japan’s Red Data Book.In 2015 the Hokkaido local government estimated the total population on the island at 10,600 bears. Life span: Unknown but assumed to be around 20 to 30 years in common with other brown bears in the wild. Food: The diet of these omnivorous bears varies according to the local availability of foodstuffs and includes nuts, pinenuts, berries, acorns, pine bark and sap, grasses and their rhizomes, lilly and other roots and bulbs. Meat includes fish, small and sometimes large mammals, birds, larvae, ants and other insects. Although encounters are rare, Ussuri brown bears will attack Asiatic black bears but fatalities have not been recorded. Undoubtedly black bears will be eaten as carrion if found. Ussuri brown bears will feed on Amur (Siberian) tiger kills and are themselves a prey animal of the tigers. There is evidence to suggest that, in Japan at least, U a lasiotus is moving towards a largely herbivorous diet (see “More Information” below). Behaviour:. The bears den in the winter, mainly in excavated burrows or within rock outcrops but also in nests built on the ground. They are solitary except during mating and when with cubs. Cubs are born in the winter den and will remain with the mother for two to three years during which time she will not become pregnant again. Females are sexually mature at around three years of age. Threats: Legal hunting in Russia and Japan and poaching across the range. The illegal body parts trade, some animals may be taken for use in bear-baiting, loss of habitat and associated human conflict particularly in Hokkaido, Japan. *Males can be up to twice the size of females ranging in weight from around 200 to 600 kg. ( 440 lbs - 1,300 lbs ).
