shaggygod.proboards.com/ ‘It had been completely consumed’: Grizzly bear eats black bear in Banff Colette Derworiz, Postmedia News | 22/08/13 | A large male grizzly bear is showing everyone who’s boss in Alberta’s mountain parks. Earlier this month, officials closed the Sundance Canyon area in Banff National Park after a group of hikers came upon a bear known as No. 122 feeding on a carcass. They reopened the trail late Tuesday after he moved on. During the investigation into the incident, officials determined the carcass was a small black bear. “It had been completely consumed,” said Steve Michel, a human wildlife conflict specialist with Banff National Park. “There was nothing remaining other than a skull, a hide, the four paws and some bones.” It’s believed it was a predatory attack on the black bear. “There were indications the black bear was foraging on the trail at the time,” he said. “It looks like that black bear just happened to find himself in the wrong place at the wrong time when a very large grizzly bear came by.” Michel said he didn’t expect there was much of a fight. "I don’t think there would have been much of a brawl that took place. It would have been fairly quick." “This is grizzly bear No. 122, so he’s a very large grizzly bear,” he said, noting it’s a 225- to 275-kilogram grizzly bear killing a 45-kilogram black bear. “I don’t think there would have been much of a brawl that took place. “It would have been fairly quick.” Although it’s not a common occurrence, Michel said there are other documented cases of grizzly bears feeding on black bears — including No. 122 eating another small black bear around the same time last year. “He’s definitely the dominant animal out on the landscape, so there are very few animals that would compare against him in terms of size,” he said. Meanwhile, another closure was put in place in the Marble Canyon area in Kootenay National Park due to a large grizzly bear feeding on an elk. “We did have a situation where people inadvertently passed really close by,” said Omar McDadi, spokesman for Lake Louise, Yoho and Kootenay national parks. The closure, which will be in place until the bear finishes the carcass, includes the Marble Canyon interpretive trail and surrounding area, the Tokumm Creek trail up to Kaufmann Lake, the connector trail to the Ochre Trail junction and the Helmet/Ochre trail. It’s possible the bear is again No. 122, although McDadi said that hasn’t yet been confirmed. As a precaution, officials have evacuated 12 backcountry users from Rockwall trail by helicopter. “Their main access point is through Marble Canyon,” he said, noting people who are still on the trail are being asked not to come down through the closed area. __________________________________________________________________ __________________________________________________________________ ► news.nationalpost.com/2013/08/22/it-had-been-completely-consumed-grizzly-bear-eats-black-bear-in-banff/

shaggygod.proboards.com/ Grizzly vs Black Bear Sow with cubs "Was out hunting with my dad tonight and seen a grizzly bear 40 minutes outside of Whitecourt Ab. Got the camera recording and drove up to him only to find him digging the roof off a bear den that had a black bear sow and three cubs cornered inside of it. In the video the sow tried to fight her way out and one of the cubs tried to make his escape. The grizzly got the one cub but the sow and other two cubs made it away. Craziest thing to watch from less the ten yards away sitting in the truck."

The Grizzly Almanac:
The Blackfeet Indians called it ( grizzly ) "The Unmentionable One" or "The Real Bear" ( nitakyaio ). They called the black bear merely "Bear" ( kyaio ), denoting its lesser status.
Compared to the mighty grizzly, the black bear is lighter, weaker, and usually less aggressive. Black bears have smaller home ranges and a greater adaptability to human activities, often learning to adapt to human ways when the grizzly chooses to move elsewhere. Because black bears tend to feed more often during the day, and grizzlies tend to be crepuscular, encounters between the two species are kept to a minimum. When meetings do occur, the black bear is usually submissive, fleeing whenever possible. There are many instances of grizzlies attacking and killing black bears, especially cubs, and one documented account from 1997 of a grizzly digging out a hibernating black bear and eating it. In competition for food, the larger grizzly usually displaces the black bear. But when grizzly populations decline, the black bear is quick to take over. As grizzlies declined west of Canada's Hudson Bay, black bears took over the former grizzly territory. A similar situation occurred in central Alberta's Swan Hills area, when black bears extended their range into the hills as grizzlies declined. Similar interrelationships have been noted between wolves and coyotes, with the latter spreading rapidly as wolf populations across the continent have plunged. Mother Nature, it seems, abhors a vacuum.

This is true. Other than man-kind ( with guns, poison, traps, or environment destruction ) the most likely killer of a bear is a bigger stronger bear. This is why I have strong doubts about any tiger found feeding on a bear carcass as being evidence of a tiger killing said mature male bear.

Where black bears and grizzlies live in same locations in N. America, black bears have a dangerous enemy.

Damn, that is a harsh video, but that is nature, what can we do. Those are black bears by the way. There are no brown bears in Arizona. You can see the black bear's climbing ability.

An incident of polar bear infanticide and cannibalism on Phippsøya, Svalbard A case of polar bear infanticide and cannibalism is reported from Phippsøya, Svalbard. In this instance, a cub of some 7 months was killed by an adult male bear, which was in poor condition, in the close proximity of the mother, which was also in poor condition. It seems probable that the attack was made for nutritional gain. .. For example, intraspecific aggression and cannibalism were predicted to increase in polar bears with climate warming (Derocher et al., 2004,Table 1). Observations of infanticide and cannibalism by thin adult males on land during the open water period have been documented (e.g., Lunn & Stenhouse, 1985; Derocher & Wiig, 1999; Amstrup et al., 2006; Stone & Derocher, 2007). Such events have been known to occur for many years and, although their significance is unclear, there is some evidence suggesting the frequency of occurrence is increasing in areas where bears fast on land for extended periods. ... www.google.com/amp/s/www.researchgate.net/publication/231930267_An_incident_of_polar_bear_infanticide_and_cannibalism_on_Phippsoya_Svalbard/amp

We report three instances of intraspecific killing and cannibalism of young polar bears by adult males on the sea ice in Svalbard in summer and autumn. During breakup and melting in summer, the area of sea ice around the Svalbard Archipelago declines to a fraction of the winter total, and in many areas it disappears completely. As the area of sea ice that polar bears can use for hunting declines, progressively fewer seals are accessible to the bears, and therefore the bears' hunting success likely declines as well. Thus, at this time of year, young polar bears may represent a possible food source for adult males. As the climate continues to warm in the Arctic and the sea ice melts earlier in the summer, the frequency of such intraspecific predation may increase. www.researchgate.net/publication/285952751_Observations_of_Cannibalism_by_Polar_Bears_Ursus_maritimus_on_Summer_and_Autumn_Sea_Ice_at_Svalbard_Norway#pf3

Merriam Webster: 1- : the usually ritualistic eating of human flesh by a human being 2- : the eating of the flesh of an animal by another animal of the same kind Bears will eat bears. What are the facts?
Interspecific - a grizzly eats a black bear. Intraspecific - a grizzly eats a grizzly - a true cannibal.

Cannibalism on rise among polar bears, say Russian scientists Agence France-Presse Cases of polar bears killing and eating each other are on the rise in the Arctic as melting ice and human activity erode their habitat, a Russian scientist said Wednesday. “Cases of cannibalism among polar bears are a long-established fact, but we’re worried that such cases used to be found rarely while now they are recorded quite often,” said polar bear expert Ilya Mordvintsev, quoted by Interfax news agency. “We state that cannibalism in polar bears is increasing,” said Mordvintsev, a senior researcher at Moscow’s Severtsov Institute of Problems of Ecology and Evolution. Defend democracy. Click to invest in courageous progressive journalism today. Speaking at a presentation in the northwestern city of Saint Petersburg, he suggested that the behaviour could be due to lack of food. “In some seasons there is not enough food and large males attack females with cubs,” he said. The rise in cases may also be partly due to more people working in the Arctic and reporting such behaviour, he said. “Now we get information not only from scientists but also from the growing number of oil workers and defence ministry employees.” This winter the area from the Gulf of Ob to the Barents Sea, where polar bears used to hunt, is now a busy route for ships carrying LNG (liquefied natural gas), Mordvintsev said. “The Gulf of Ob was always a hunting ground for the polar bear. Now it has broken ice all year round,” he said, linking this to active gas extraction on the huge Yamal peninsula that borders the Gulf of Ob, and the launch of an Arctic LNG plant. Quitting normal hunting grounds Russia, already a key global oil and gas exporter, is keen to develop its LNG potential in the Arctic. It has also significantly upgraded its military facilities there. Another Russian scientist, Vladimir Sokolov, who has led numerous expeditions by the Arctic and Antarctic Research Institute, based in Saint Petersburg, said this year polar bears had mainly been affected by abnormally warm weather on Spitsbergen Island to the west in Norway’s Svalbard archipelago, where there have been no ice floes and little snow. Russian researchers have recorded growing numbers of polar bears moving away from their traditional hunting grounds as ice melts due to global warming. Over the last quarter-century, Arctic ice levels by the end of summer have fallen by 40 percent, said Sokolov. He predicted that polar bears would eventually no longer hunt on sea ice and be confined to shore areas and high-latitude archipelagos. Russians living in Arctic settlements have sounded the alarm over dozens of bears entering areas of human habitation, particularly to raid rubbish dumps for food. www.rawstory.com/2020/02/cannibalism-on-rise-among-polar-bears-say-russian-scientists/

INTRASPECIFIC PREDATION OF A SUBADULT BROWN BEAR IN GREECE.Intraspecific predation (cannibalism) in brown bears (Ursus arctos) is a behavior rarely documented, and it remains poorly understood. In April 2010 we documented the probable killing and partial consumption of a subadult female bear by a subadult male bear; both bears had been captured during a telemetry study in northern Greece. In-traspecific killing was supported by a match between the inter-canine distance of the male, fatal wounds on the female, and the absence of other bear tracks at the trap site; consumption of the subadult female by the subadult male was witnessed directly by the trapping team. This is the first reported case of probable intraspecific killing and predation of a sub-adult female by a subadult male brown bear. Though intraspecific predation appears to be a rare phenomenon , trapping teams should always strive to reduce the time an animal is captured in a trap, such as by using trap alarms. . 1. (A) Subadult female brown bear probably killed by a subadult male brown bear during a trapping session in northern Greece in 2010. The subadult male eventually fed on the subadult female, consuming parts of the groin area. (B) Close-up image of the head and neck region. The wounds to the carotid artery are visible. www.researchgate.net/publication/279443521_Intraspecific_predation_on_a_subadult_brown_bear_in_Greece

^ I hate this. Polar bears, which are usually solitary animals, are being forced to come together and fight for territory and lack of food that wouldn’t normally be required. I definitely think global warming is real.

Andean Bear Cannibalism in Northern Ecuador
The Ursids are known to occasionally prey on their congeners. Adult bears may kill cubs or unrelated juveniles and use them as a food resource or to stimulate the estrus after the female has lost its progeny (Swenson et al. 1997, Derocher and Wiig 1999, Karamanlidis et al. 2015). In extended periods of food deprivation, large males may kill and consume other bears of any size, sex, or gender. There is one reported case of cannibalism for the Andean bear, involving a radio-collared bear that was shot when it was seen feeding in a cornfield. The bear ran away and died in the forest, and then was devoured by several bears. This conclusion was made upon seeing diverse sizes of footprints, feces, and platforms or tree nests around the carcass (Castellanos 2006).
On September 15, we received inactivity signals for 2 days straight from Cosanga’s radio collar. We rapidly headed to its location, and found its remains within trampled vegetation and bushes in an approximate 150-m2 area. This scene was similar to ones we’ve found many times when bears attacked cattle (Castellanos 2002). Huge footprints left by the perpetrator and voluminous feces left beside the skeleton makes us believe they belong to a large male bear. We also found other footprints and small feces around the attack site, suggesting that the carrion was consumed by smaller bears, as previously reported by Castellanos (2006). Intraspecific depredation or cannibalism is a rarely-observed and little understood behavior in bears (Davis and Harestad 1996, McLellan 2005, Stirling and Ross 2011). This behavior may be more common in Andean bears than indicated by the paucity of reports because it is unlikely to be observed without radiocollars.

Reply #38 - Suddenly, the Andean bear feels more like a "real bear."
