Bolushi A grizzly has never killed an adult polar bear. There was some idiotic teenager on Domain of the Bears who kept saying that (per my dms with me he seemed like a really bored and retarded little guy) and the two (fairly popular) websites writing this stuff had no sources attached. Then I cross-searched it on Google Scholar and Google Books and there were no results. As far as I know both of them have never engaged in physical combat with each other, except for grizzlies killing subadult polar bears much smaller than themselves. The reason for grizzlies being dominant at whale carcasses isn't that they'd win in a fight. For polar bears a whale carcass is nothing fancy; they are used to energy-rich food and they are full-time predators. Even a small cut in their flesh by a small grizzly's claws could mean death when the wound gets infected. On the other hand, the tundra grizzlies turn overly aggressive as a whale carcass means a lot of calories. They eat berries/roots for the majority of the time and finding something like this is the "holy grail". A grizzly bear also has shit to fear should he get injured, there are a few cases of three-legged bears having no problem to survive and keep going. So it's kind of a psychological scenario where the grizzly has the advantage and he knows he has much less to lose. The only time of the year when polar bears engage into full-blow fights is when mating with the females (that's basically where most deaths happen in all predators). And I am sure a grizzly would just get the fuck out if he considered approaching a female polar bear when a male polar bear ready to go at it is nearby. This snippet is from an Attenborough documentary and the male on the right was completely fucked up and exhausted as he had to fight off multiple other males in order to earn the female's trust. Later off they wandered onto a snowy hill for courting and the male was completely limping whereas the female just kept running eagerly. It was hilarious to watch.

The polar bear from Foxe Basin and most male polar bears will win if they outweigh the Kodiak bear by 200 pounds or more.
I think the Kodiak bear will beat male polar bears from Svalbard (the same weight as Peninsula Alaskan grizzlies) and Churchill.
Regarding aggression, the polar bear might be more aggressive as it encounters more animals than the Kodiak bear does.

One more thing to point out, the polar bear is the slightly better grappler but the Kodiak bear has longer claws and surprisingly wider paws.

apparentely he's the top bear at brooks falls these days, but still funny because he got clapped hard by the younger and faster bear 68 here Thankfully bear fights are usually very chill. Hence why bear 747 and bear 856 have been dominant over brooks falls for 10 years while the mapogos reign only lasted 2-3 years If I could be any wild animal I'd be a grizz, their lives are so easy and chill and once they grow into adulthood death is nearly impossible. Morphologically you're almost there, well maybe a female grizz. But I wouldn't mess with ya! *Reminder to self never to call Bolushi slut features. |

I don't but a news article quoted him saying grizzlies do kill female polar bears hibernating. |

/\ Male polar bears do not hibernate and being much bigger than the grizzlies are immune to being killed by their brown cousins.
The polar bears encountered by the grizzlies are not even the largest yellowish white bears ot average weights.

Average male polar bear: Tracks: A polar bears forepaw is approximately 5 ¾ inches long and 9 inches wide while the hindpaw usually measures 13 inches long and 9 inches wide. The toes form an arc similar to a black bear’s track. A polar bear’s track is generally only visible in soft snow or mud and may show fringed edges due to the hair on the paw (Brown 1993, p 76). The bottom of the paw is completely covered with fur. The claws are black, short and stocky and are usually not visible in the track (Stirling and Guravich 1990, p 39). bear.org/polar-bear-facts/An average of 9 inch could mean 22.5cm paw width. The average male polar bear’s paw width is slightly wider than that of the largest male Ussuri brown bear and male Kamkatcha brown bear. Large male polar bear: Polar bears have large paws compared to body size, reaching 30 cm (12 in.) in diameter. The large paws of a polar bear act like snowshoes, spreading out the bear's weight as it moves over ice and snow. seaworld.org/animals/all-about/polar-bear/characteristics/The only brown bears with wider paws than a yellowish white bear would be the kodiak and peninsula Alaskan brown bear. 30cm is the widest paw width a male polar bear has achieved so far. Maybe Stan’s paws are much larger if 30cm is for the largest common male. Large Peninsula Alaskan brown bear: 1954: Alaska peninsula brown bear hunting record, estimated to weigh 2200 lbs, 35 years old, front paw width of 13 inches (33 cm), skull scored 34 9/16 (not recognized by Boone and Crockett):  beargorillarealm.proboards.com/post/7972The paws of the brown bear are quite large. The rear feet of adult bears have been found to typically measure 21 to 36 cm (8.3 to 14.2 in) long, while the forefeet tend to measure about 40% less in length. All four feet in average sized brown bears tend to be about 17.5 to 20 cm (6.9 to 7.9 in) in width. In large coastal or Kodiak bear males, the hindfoot may measure up to 40 cm (16 in) in length, 28.5 cm (11.2 in) in width, while outsized Kodiak bears having had confirmed measurements of up to 46 cm (18 in) along their rear foot. Brown bears are the only extant bears with a hump at the top of their shoulder, which are made entirely of muscle, this feature having developed presumably for imparting more force in digging, which is habitual during foraging for most bears of the species and also used heavily in den construction prior to hibernation. www.inaturalist.org/guide_taxa/889098#:~:text=The%20paws%20of%20the%20brown,to%207.9%20in)%20in%20width. When comparing the sources, it seems that a large male polar bear actually has slightly wider fore paws than a large kodiak and coastal brown bear (30 cm vs 28.5 cm). I have mistaken length for width  . My apologies . Outsized kodiaks might have 46 cm measurements in the rare foot not fore paw, I think Stan might actually have the widest paws. Not a surprise, polar bears need wider paws to walk on thin ice.

/\ A bit of correction on my part. 28.5 cm for the Kodiak bear refers to the hind foot width. However, it is said that all four feet average in average brown bears is 17.5 cm to 20cm in paw width is less than the average width of the male polar bear which is 22.5cm.
Also the Peninsula Alaskan brown bear which has a 33cm paw width weighs 2200 pounds while a large polar bear (common weight) probably weighs 1540 pounds at most (30 cm paw width). Therefore, Stan and other exceptionally large male polar bears might have paw width that surpasses 33 cm (just my opinion).
