It is possible that these tigers living in Bhutan may prey upon Asiatic black bears and possibly sloth bears. Himalayan brown bears are now either extremely rare in Bhutan or missing completely from their former range.

Staff at the nature reserve in the Amur region where Boris roams said they had found what little remained of the bear Tuesday. “By the time we arrived at his hunting-ground, there wasn’t much left of Boris’ feast,” Vyacheslav Kastrikin, the park’s deputy director, told Interfax. “So it was hard to say if it was a brown bear or an Asian black bear.”  *This image is copyright of its original author  *This image is copyright of its original author  *This image is copyright of its original author  *This image is copyright of its original author
An unusual trait of bears is the fact that they are the only large members of the order Carnivora that are looked upon by other carnivores as being both predator and prey. A pack of wolves will not seek out a cougar, a wolverine, or a tiger for a meal. A tiger might seek out wolves or a leopard to kill, but his purpose is not driven by hunger. Bears, on the other hand, are sought after for food especially when other prey choices are scarce.
A grizzly might kill and feed upon the cubs of other predators but I don't believe that he purposely spends a day looking for them. He is merely an opportunist.

51 long term monitoring of prey species, habitat type and mitigation measures is proposed to take up for proper conservation and management plan. 2006 Relationship of Bears and Tigers in the Russian Far East Ivan Seryodkin1, Yuri Petrunenko1, Dale Miquelle2, 1Pacific Geographical Institute, FEB RAS, Vladivostok, Russian Federation; 2Wildlife Conservation Society, New York, NY, Contact: [email protected] In the southern Russian Far East, brown bears (Ursus arctos) and Asiatic black bears (U. thibetanus) co-exist with Amur tigers (Panthera tigris altaica). In the Sikhote-Alin Reserve the relationships between these three species were studied in 1992-2013 during extensive telemetry and snow-tracking efforts. Bears often fed on Amur tiger kills. Of the 353 tiger kills we found during the non-denning period for bears (April-November) 62 kills (17.6%) were used by bears including 37 (60%) brown bear, 9 (14%) by Asiatic black beer and 16 (26%) of uncertain bear species. The proportion of tiger prey scavenged by bears is likely higher than what our data indicate, since utilization by scavengers was not always complete when we visited kills. Often bears fed on kills after tigers abandoned them. However, in at least in 8 cases (12.9%) bears displaced tigers from a kill, and in 7 cases (11.3%) both tigers and bears utilized a kill during the same period. Analysis of prey items revealed that bears represent 3.4% in the diet of tigers in the non-denning period (1.7% for each species of bears). In 44 recorded encounters between tigers and bears, the tiger initiated contact in 12 cases while the bear initiated contact in 8 cases, while in all other cases the individual initiating contact could not be determined.

I would think ustaad was around 4, which would mean he's just coming into his breeding years but not in his mature, prime years just yet. I still consider 3-5 years as being sub adults. They usually have just left their mother (within a year) and they still have a bit of growing to do. Their life experience is still lacking and they have just started to test themselves so I don't think their confidence is quite there yet.(08-01-2014, 02:29 AM)Pckts Wrote: Great story, Obviously I think that if you have a adult T24 you probably have a different outcome. 
Both tiger and bear are the ultimate beasts. Bears are known for brutal strength where as tiger strength is athleticism combined with brute force. It is interesting match up and is tough to say who wins when equal size specimens fight.
When equal size sloth bear fights equal size bengal tiger the winner would be the sloth bear IMO because sloth bears have fearsome reputation and are believed to be pound for pound the strongest bears. This can almost be applied to himalayan black bear they are also believed to be some of the strongest bears pound for pound. So, the tiger may be backing off after some fight if they are of same size. But if the tiger is bigger, he would be obviously the winner. In case of siberian tiger too, the tiger domination depends on the tiger's athleticism and it's ability to grab the throat of the bear as soon as possible if they are of same weight. If the tiger is bigger, the tiger should be the winner.
America's celebrity jaguar 'El Jefe' is a bear hunter
By Ethan Shaw October 19 2016 http://www.earthtouchnews.com/natural-wo...ear-hunter A male jaguar called El Jefe ("The Boss") has been in the news a lot lately. He's the only known wild representative of his kind in the United States, and his turf – the Santa Rita Mountains of southeastern Arizona – is being considered for a hugely contentious open-pit copper mine. And according to a recent Smithsonian Magazine profile, America's celebrity jaguar is also a bear killer.  *This image is copyright of its original author El Jefe, the only known wild jaguar in the United States, wandering the Santa Rita Mountains. Image: Conservation CATalyst While shadowing El Jefe in the Santa Rita backcountry, biologist Chris Bugbee discovered the strewn bones of a black bear, including a crushed, tooth-punctured skull (photographer Bill Hatcher was able to capture several snapshots of the remains). Assisting with the El Jefe-tracking task was Bugbee's dog Mayke, a Belgian Malinois specially trained to sniff out jaguar and ocelot poop. Back at the lab, analysis later confirmed that jaguar scat collected at the scene contained bear hairs. According to Bugbee's colleague (and wife) Aletris Neils, with whom he runs the nonprofit Conservation CATalyst, the bear skeleton likely belonged to a young adult sow. The unusual find, Bugbee suggests, marks the first known instance of a jaguar preying on a black bear. Such an event could only occur in the American Southwest or northern Mexico, where the stomping grounds of the mainly temperate black bear and the mainly tropical/subtropical jaguar overlap. "It was north against south, and south won," Neils tells Smithsonian. As El Jefe's bear lunch suggests, jaguars are opportunistic hunters. They often actively prowl in search of prey, then attempt to stalk and kill any they encounter. More comfortable getting their paws wet than most felines, they'll also cruise riverbanks and wetland fringes questing for huge capybaras, as well as caimans, which can make up nearly 50 percent of jaguar diets in water-logged habitats. And as this footage plainly shows, the bigs cats are not afraid to pounce on full-sized caimans in their watery element, showing some mind-boggling strength hauling the reptiles ashore. That same muscle power and ease in the water come in handy when hunting supersized rodents – just watch this Brazilian jaguar in full submarine mode as it wrestles a capybara from the depths. In the Smithsonian article, Bugbee speculates El Jefe could have taken down the black bear by ambushing the unsuspecting animal as it foraged. The bear's mangled skull fits a distinctive pattern of jaguar kills: the big cats commonly dispatch capybaras by puncturing their braincase, a feat that requires precise fang placement and massive crushing power. (Jaguars have proportionately the strongest bite of any big cat, which also serves them well when munching turtles.) Interestingly, some evidence suggests that spectacled bears, the only South American representatives of the bear family, avoid jaguars where the two share habitat. More than a hundred species have been recorded as jaguar fodder across the cats' range, although recent research suggests they especially favour capybara, caiman, collared peccaries (or javelina), nine-banded armadillos, wild pigs, white-nosed coatis and giant anteaters (though as we saw just last month, giant anteaters aren't pushovers when it comes to jaguars). The study, nicely summarised here, speculated that jaguars might have escaped the great megafaunal extinctions at the end of the last ice age in the Americas by adapting to smaller prey, and consequently diminishing in size themselves. Jaguars only rarely tackle adult South American tapirs, the biggest terrestrial mammals in the Neotropics, although a beefy male named Aratiri in the Argentine Atlantic Forest is an accomplished tapir-hunter.  *This image is copyright of its original author Aratirí, seen here with a tapir carcass, is one of the largest jaguars known to inhabit the Atlantic Forest, which spans parts of Brazil, Paraguay and Argentina. Image: Emilio White/Proyecto Yaguarte El Jefe's bear lunch sheds a little light on the "phantom ecology" of jaguars in the American Southwest, which were mostly shot and poisoned out by the mid-twentieth century. Since the cats weren't well studied before effectively disappearing, we don't know much about their food preferences. The predators once flourished alongside grizzlies and Mexican wolves in the isolated mountain ranges of Arizona and New Mexico, along the Mogollon Rim, and occasionally beyond: as far north as the South Rim of the Grand Canyon, and eastward into South Texas thornscrub (and maybe even the swampy Texas-Louisiana border). Today, the nearest population of breeding jaguars to the US border exists in eastern Sonora. El Jefe, who first came on biologists' radar in 2011, is only the latest of a string of male jaguars – known to be impressive wanderers – to reclaim southern Arizona territory over the past couple of decades. (His most famous predecessor was Macho B, a longtime resident of the state's Tumacacori Highlands until he was controversially euthanised in 2009.) To encourage more of the great spotted cats to repopulate borderland habitat, conservationists hope to establish protected corridors between the Sonoran jaguar population (which finds refuge in the remote Northern Jaguar Reserve) and the US line – but obstacles such as the proposed copper mine, not to mention Donald Trump's visions of "an impenetrable and beautiful wall", threaten to stand in the jaguars' way. 
A jaguar living in wild in the USA today ? I hope there is a divinity of the jaguars who will protect it ...
@Pckts:
I believed the jaguars had been totally exterminated from the USA since a long time. Sincerely, I was surprised to know there is a living one, now, in this country. Is it the last survivor, or the first one returning into this state ? On the other hand, when I consider the social and politic situations along the United States - Mexico frontier, that is difficult to believe how a jaguar from Mexico could be able to come back in the USA. Thus, a few "American" individuals should have been able to survive so much time ? Amazing ! I would like to dream about, as you said, a "beginning". If the authorities could help him by protecting him to rebuild a lineage... |
