Although Fitzgerald shot the bear last September, Boone and Crockett, which certifies hunting records, has only now determined the grizzly, with a skull measuring 27 and 6/16ths inches, is the biggest ever taken down by a hunter, and the second largest grizzly ever documented. Only a grizzly skull found by an Alaska taxidermist in 1976 was bigger than that of the bear Fitzgerald bagged. Fitzgerald brought down the bear from 20 yards, with one shot to the neck from his Sako 300 rifle. He said he and hunting buddy Justin Powell knew from the tracks he was on the trail of a massive grizzly, but only learned this week that he held a world record. From, "The Bear Almanac" by Gary Brown. Grizzly skull ( picked up ) in Lone Mountain, Alaska. Score: 27 and 13/16. - From the Old West days of the great buffalo herds. *If this found skull was from a typical grizzly that followed the bison herds, then their average was bigger than today's mountain grizzlies. Also note that in the books I've read concerning the historical grizzlies; they all stated that the grizzly of the prairie were bigger than the Rocky Mountain grizzly. That skull ( if simply a typical-sized grizzly ) would probably be near the size of a coastal brownie.

Yes, its obvious and we didn't need to see a study to know that subadults and females are mostly targeted. Every predator does the same, no one targets the adult males. Anyhow, we do have an account of a Carpathian brown bear killing 2 bull bisons of 8 and 11 years old in Poland.
True. ( IMO ) 650-pounds is probably the average or perhaps most common weight-class chosen by the brown bear.

shaggygod.proboards.com/ Bears as predators.... The size of a carnivore strongly influences the size of the prey it is capable of killing, the maximum size of prey killed being slightly larger than that of the predator. For example, a 100 kilogram (220 pound) bear can handle prey weighing up to roughly 150 kilograms (330 pounds). Polar bears prey primarily on the smallish (60 kilogram/ 130 pound) ringed seal and the larger (up to 360 kilogram/790 pound) bearded seal. In some instances, polar bears can remove up to 44 percent of the ringed seal pups born in a particular area. They are also known to kill walruses (500 kilograms/1,100 pounds) and white whales weighing up to 600 kilograms (1,320 pounds). Brown bears, while primarily vegetarian, can also prey significantly on hoofed mammals. In some areas, adult males reportedly kill three or four adult moose (450 kilograms/990 pounds) per year, with females killing an average of one. Caribou (150 kilograms/330 pounds), musk ox (250 kilograms/550 pounds), elk (200 kilograms/ 440 pounds), and bison (500 kilograms/ 1,100 pounds) have all been taken. Brown bears also prey on ground squirrels, trout, and salmon, but usually only when they are sufficiently abundant to make hunting them energy-efficient. ANDREW E. DEROCHER AND IAN STIRLING, Bears: Majestic Creatures of the Wild (1993). Bears typically kill using brute force and do not seem to exhibit any stereotyped killing postures or behaviours as seen in canids and felids (R. Boertje, pers. comm.; J. Hechtel, pers. comm.). Polar bears and brown bears have been observed to attack their prey both with bites and crushing forepaw slaps, apparently to whatever region of the prey’s body is accessible (Murie, 1985; Boertje et al., 1988; Case & Stevenson, 1991; M. Ramsay, pers. comm; J. Hechtel, pers. comm.). Sacco, T. and Van Valkenburgh, B. (2004), Ecomorphological indicators of feeding behaviour in the bears (Carnivora: Ursidae). Journal of Zoology, 263: 41–54. We are going to search for all reliable modern data of bison killed by bears.

Warsaw posted some time ago: The bear killed two bison in the Bieszczady Mountains BIESZCZADY, LESKA DISTRICT. On Saturday 18 November, not far from the village of Olchowa, in the middle Wielkie forestry area, two dead bison were found in the Lesko Forest District. Both were not far from each other. The first of them, the 8-year-old bull, left only the front part, including the head. However, the body of the second individual, also a bull but 11 years old, has been preserved in a better condition. He had a broken spine and bear's claws. - We informed the Poviat Veterinary Officer in Sanok, the branch of the Polish Academy of Sciences in Ustrzyki Dolne and the Association of European Bison Friends - says Wojciech Jankowski from the Lesko Forest District. - On the evening of November 19, the site and the remains of the bison were inspected. Tissue samples for genetic tests and the presence of tuberculosis bacilli were collected - bison in Bieszczady are suffering from diseases. On the basis of the inspection of the place of the event and the remains of animals, veterinarians excluded human interference, while the bear's attack was taken as the most probable cause of the fall of the bison, as indicated by the injuries and numerous tracks of this predator, as well as its lair. - A few years ago in this area we had a case of killing a bison by a bear, which for the following weeks was nourishing its prey just at the beginning of winter - reminds Wojciech Jankowski. - It looks like the predator and this time took the opportunity to catch more art from bison herds moving towards their winter refuge. A deep gorge, where the driven bison breaks legs or falls over, gives the predator a predominance. Forest District Lesko will apply to the Regional Directorate of Environmental Protection in Rzeszów for permission to prepare skulls of dead bison for educational purposes.

CARPATHIAN BROWN BEAR (URSUS ARCTOS ARCTOS) KILLS 2 BULL BISONS IN POLAND
Both were not far apart. Of the first of them, an 8-year-old bull, only the front part remained, including the head. In contrast, the body of the second individual, also a bull but 11 years old, has been preserved in better condition. He had a damaged spine and bear claw wounds. - We have informed this fact of the Poviat Veterinary Officer in Sanok, the branch of the Polish Academy of Sciences in Ustrzyki Dolne and the European Bison Friends Association - says Wojciech Jankowski from Lesko Forest District. - On Sunday, November 19, a visual inspection of the place and the remains of the bison was carried out. Tissue samples were taken for genetic testing and for tuberculosis - bison diseases in the Bieszczady Mountains. On the basis of a visual inspection of the incident site and animal remains, the veterinarians ruled out human interference, while a bear attack was assumed as a very likely cause of the fall of the bison, which is indicated by the injuries and numerous tracks of this predator, as well as its lair. - A few years ago in this area we had a case of a bison killed by a bear, which for several weeks ate its prey just at the threshold of winter - reminds Wojciech Jankowski. - It seems that the predator also took this opportunity to catch more animals from herds of bisons moving towards their winter refuges. A deep gorge, to which a bison breaks legs or falls, gives the predator an advantage. Forestry Lesko will apply to the Regional Directorate for Environmental Protection in Rzeszów for permission to prepare skulls of fallen bison for educational purposes. translate.googleusercontent.com/translate_c?depth=2&hl=pl&nv=1&rurl=translate.google.com&sl=pl&sp=nmt4&tl=en&u=http://gospodarkapodkarpacka.pl/news/view/23091/niedzwiedz-zabil-dwa-zubry-w-bieszczadach&xid= Evidently the same incident as reported by Warsaw.

Wow you got me Kodiak. I had no I idea that Poland had Bison? Are they the same as American Bison? Yeah, The European bison (Bison bonasus) which is a close cousing of the American bison. It is the largest wild land animal in Europe. Adult bulls average about 1400 lbs, but can reach a weight of 900 kg (1985 lbs)

allaboutbison.com/bison-world-news/europe/european-bison/ The European Bison Conservation Center (EBCC) is the International Network gathering European bison breeders from Poland, Germany, Russia, Sweden, Spain, Romania, Belgium, Czech Republic and Belarus. Bialowieski Park Narodowy The European bison featured two distinct subspecies – a lowland bison, also called the Białowieża bison Bison bonasus bonasus and the mountain Caucasian bison Bison bonasus caucasicus. Poland: 1567 animals 2015. (some 2016 data shows Poland having another 131 animals, these are not included in the total at the bottom) *Fantastic find there King Kodiak. My two cents.

2 adult bull bisons, one 8 years old and the other 11, killed by the Carpathian brown bear in a very short time. How many accounts we have like this before? Very very few. Shows what a brown bear is capable of doing. Pablo.

2 adult bull bisons, one 8 years old and the other 11, killed by the Carpathian brown bear in a very short time. How many accounts we have like this before? Very very few. Shows what a brown bear is capable of doing. Each year, in early Spring when the bears are waking-up and hungry ( Yellowstone ) the bears are commonly found feeding on the remains of bison that didn't make it through the harsh Winter. Now; I am sure that the vast majority of these sightings are just that - a grizzly feeding on a found carcass. But I would wager that now and then the grizzly is seen feeding on the carcass of a bison he killed himself. Not all is witnessed. My nickel.

A grizzly killed a healthy adult bison cow Later in the week, we were alerted to a bison carcass by Caroline, an interpretive ranger. With much yelling and eyeing of the forest edges, we flushed the 30+ ravens off the carcass as we approached. The necropsy found significant subcutaneous hemorrhaging on the hump of the very healthy (lots of fat in the hump and marrow) cow bison, indicating that she was killed by a bear. Grizzly bears often attack from the front, as opposed to wolves, which typically attack from the rear. The bears basically give their prey a good swat in the face or jump them from the side and latch onto their back. www.aspiringecologist.com/2010/03/keys-bleh.htmlA grizzly killed a healthy adult bison cow.

shaggygod.proboards.com/thread/365/grizzly-bear-bison-relations?page=3 A remarkable encounter and equally an impressive recounting of the event (remarkable detail): I drove east along the road, observing the movement of the bears and bison approximately 15 meters away. After trotting about 50 m, the bison broke into a full run. The adult bear then chased the bison at full speed. At the crest of the hill above the Yellowstone River, the bear swiped its paw across the hindquarters of the bison, knocking the bison's back legs out from under it. The bison began to slide down the steep embankment of the hill on its back. After striking a tree with considerable force on its front quarters, the inverted bison continued to slide toward a pedestrian boardwalk at the base of the hill. The grizzly leaped onto the stomach of the inverted bison and skidded down the hill on top of it while attempting to bite at the bison's neck. The bear and bison came to a stop at the base of the hill on the pedestrian boardwalk. The bear continued to bite and pull at the bison's neck while the bison tried to get to its feet. The bison managed to stand and struggled to remain standing, but the bear continued to pull the bison back down to the ground. When the bison did stand, its hind legs buckled under its own weight. The bear took advantage of this and jumped onto the back of the bison, biting and clawing at its back, inflicting a number of bite and claw wounds around the bison's hump and lower back. With a quick head motion, the bull managed to free itself from the bear and stand up a second time. At this time, I observed that the bison's left front leg was broken. This injury may have occurred when the bison slammed into the tree while sliding down the steep hill. The bison continued attempts to stand and fought off the bear with its head and horns for several minutes. The bear stood up on its hind legs and swiped at the bull's head with its paws. The bison reacted by rearing up, which caused it to slide backward into a ditch adjacent to the Fishing Bridge boardwalk. Being in the ditch appeared to put the bison in a better position to fend off the bear with its head and horns. At this time the 2 cubs, which had been observing their mother from on top of the hill, came down and reunited with her near the bison. The bison continued to struggle to keep up-right and bled profusely from its back and hindquarters. The adult bear attacked the bison several more times, but the bison was able to use its head and horns to repel the attacks. The cubs did not participate in these attacks but remained nearby. On 5 occasions the bears left the area and were no longer visible to me, then came back and the adult attacked the bull again, but was unable to kill it. The interval between attacks increased from approximately 5 minutes to several hours between return visits. At approximately 1800 the bears left and did not return, enabling me to investigate the bison in the ditch. The bison was startled upon my approach and attempted to climb out of the ditch. It fell down and was unable to pull itself out of the mud. Due to the proximity of the bison to the main road and concerns for the safety of visitors and a construction crew working on the road bridge adjacent to the attack site, park management decided to dispatch the bison and move the carcass. After shooting the bison, the carcass was moved 0.9 km away to a location remote from public use areas. Managers hoped that the bear family group would follow the scent trail to where the carcass was disposed and scavenge the remains. The next morning (24 September), an adult female grizzly with 2 cubs returned to the area where the attack occurred. The 3 bears were identical in size and color to the bears that had encountered the bison the previous day, and I believe they were the same family group. The adult female grizzly paced, circled, and sniffed the ground as she searched the site where she had attacked the bison the day before. Several visitors saw the bears from the main road and approached them in an attempt to get pictures. As they approached, the adult bear bluff charged them and chased them back toward the road. Due to the danger that an adult female grizzly accompanied by 2 cubs posed to park visitors and bridge construction workers, the bears were hazed out of the area with cracker shells. I monitored the area where the bison carcass was moved to, but never observed the female with cubs or their tracks in the snow at the new location. Three days later, I observed a large adult male grizzly scavenging on the carcass. I observed that bear at the carcass for 5 consecutive days and then did not see it again. In that time, the grizzly consumed most of the bison. After the grizzly stopped returning to the carcass, a large male black bear (Ursus americanus) began frequenting the carcass and scavenging the remains. The black bear returned to the carcass to scavenge for several days until the carcass was entirely consumed. I did not see the female and her 2 cubs in the area again for the remainder of the season. Tooth eruption and wear from the bison's mandible indicated it was 3 1/2 years old (M. Meagher, YNP, Wyoming, USA, personal communication, 2001). Femur bone marrow was grayish-pink in color, indicating that the bull may have been in the early stages of marrow fat depletion, although not yet severely malnourished (Cheatum 1949). Visually, the bison had looked slightly thin, but there was no other evidence of poor health or injury prior to the attack or when I observed it fleeing from the bear. Wyman, Travis. 2002.
