Evidence for a black bear, Ursus americanus, killing an adult moose, Alces alces
.. The amount of vertebrate remains left in scats likely underestimates the occurrence of these food items in the diet (Putman 1984;Pritchard and robbins 1990) due to their high digestibility. As such, bone and hair are typically the only components remaining in scats, although these too may be substantially degraded (Gamberg and Atkinson 1988). in addition, American Black Bears typically remove the hide of ungulate prey prior to consumption (Austin et al. 1994), so there would be even less likelihood of finding hairs from young moose calves in the scats of American Black Bears. ...
... There is anecdotal evidence that American Black Bears in the study area prey on moose calves (Obbard et al. 2000) and even on adult moose (Austin et al. 1994). However, it is unknown how commonly such events occur. ...
... Ursus americanus feeds opportunistically, and animal matter (e.g., mammals, reptiles, birds, and insects) is consistently part of the diet (Boileau et al. 1994;Maehr and Brady 1984;Smith et al. 1994a). American black bears may kill moose (Alces alces) cows (Austin et al. 1994) and calves (Franzmann et MAMMALIAN SPECIES 647 al. 1980;Schwartz and Franzmann 1991) and white-tailed deer (Odocoileus virginianus) fawns (Kunkel and Mech 1994;Ozoga and Venne 1982). In some areas, American black bears also kill livestock (Horstman and Gunson 1982). ...
. Adult female black bears do prey on moose calves, but such predation attempts are potentially risky and a defensive cow moose can be dangerous prey for much smaller adult female black bears [51]. Such predation attempts are likely less risky for the much larger adult male black bears, and adult male black bears can even prey successfully on adult cow moose [52], so a black bear population with a lower proportion of adult males would be expected to exert less predation pressure on moose. ...
.. Solitary predators such as cougars (Puma concolor) have also suffered fatal injuries (Gashwiler and Robinette1957, Hornocker 1970, Brown et al. 1988 The black bear is reported to commonly prey on neonate and young cervids such as elk (Schlegel 1976), white-tailed deer (Odocoileus virginianus) (Ozoga and Verme 1982), caribou (Rangifer tarandus) (Mahoney et al. 1990), and moose (Ballard et al. 1979, Ballard et al. 1990, Ballard 1992. Though black bears are generally not considered to be successful predators of adult ungulates (Ballard 1992), a radiocollared adult male black bear killed an adult female moose in our study area in northern Ontario (Austin et al. 1994), and black bears were implicated in the deaths of adult caribou in Labrador (Veitch and Krizan 1996). ...

Natural Predators of Feral Hogs
Black Bear – The black bear is known to prey on feral hogs of all ages; however, the impact of predation by this bear on feral hog populations is not known. Some researchers have speculated that black bears probably kill few if any feral hogs, especially given that an adult hog would represent a formidable adversary for a black bear. In fact, in the 1920s a feral boar in the Okefenokee Swamp was reported to have killed a black bear in a fight between the two animals. Similar accounts of feral boars killing bears during fights in the Ozark Mountains of Arkansas were reported in the 1880s. Being opportunistic, black bears have been reported to raid nylon net live traps used for feral hog control at high elevations in the GSMNP to obtain any trapped hogs contained within these devices.

AMERICAN BLACK BEAR PREDATION OF AN ADULT WHITE-TAILED DEER
American black bears (Ursus americanus) are opportunistic omnivores and can be proficient predators of neonate ungulates, but predation of adult ungulates is rare. In November 2009 we investigated a probable black bear predation of a radiocollared, adult (7.5 years old) female white-tailed deer (Odocoileus virginianus) in a densely vegetated, lowland conifer forest in the Upper Peninsula of Michigan, USA. The deer carcass was 80% buried with puncture wounds and lacerations on the back and hindquarters. The hide was everted, the intestines and stomach partially eaten, the mammary glands were punctured, and the skeleton remained articulated. All woody vegetation <5.0 cm diameter within 5 m of the carcass was trampled and contained bear and deer hair. We found no evidence of other carnivores. Based on the condition of the carcass, physical evidence at the site, and the similarity of this predation to reported black bear predations, we suggest this deer was attacked and killed by a black bear.

BLACK BEAR KILLS BOAR WITH ONE NECK BITE.
“Told the game warden about some bear tracks we've been picking up around one of our hog feeders, so they set up a trap to catch him.
The bear also seems to like pork too, as we found this freshly killed hog next to the trap when we caught him, he'd broken the hog's back with one bite...."

State wildlife officials all but certain black bear killed small horse in Hinsdale
HINSDALE — Wildlife officials are all but certain that a black bear killed a small horse in its barn here late last week and dragged it 100 feet out into the yard where it was fed on by coyotes.
Kathleen Tench Adams posted on Facebook that the family’s mini-horse was pulled from its stall and killed, apparently by a bear. “We are heartbroken,” she wrote.
Andrew Madden, Western District Supervisor for the Massachusetts Division of Fisheries and Wildlife, said the incident occurred late Thursday or early Friday. Investigators, arriving on scene, found that the horse had been fed on by coyotes “for quite some time.”
Because the horse had been fed on and the ground was frozen at the time of the attack, there is no clear evidence of exactly what had occurred, however, Madden said. “We believe it was killed by a bear, but we can’t say with certainty."
It’s unusual for a black bear to go after such a big animal but it’s not unheard of, Madden said, adding investigators believed the horse weighed about 300 pounds.
Often times in such situations, the presence of feed is what draws bears into contact with livestock, Madden said. “Usually it’s an opportunistic situation."
It’s far more common for bears to go after smaller animals like backyard chickens, he said.
Black bears are omnivorous, meaning they typically feed on plants, fruits, honey, nuts, insects, small mammals and carrion. They have also been known to kill young deer or moose calves.
Residents need to be aware bears are a prominent part of the landscape in the western and central areas of the state, Madden said. “This is a good opportunity for people to take a look around and realize that they are out there.”
Madden said state wildlife personnel have no plans to attempt to track down or move the bear. He said if they start to see repeat instances of a troublesome bear in a particular area they may reevaluate the situation.

Interrelationship of Black Bears to Moose and Forest Succession in the Northern Coniferous Forest
Abstract
We compared characteristics of 2 black bear (Ursus americanus) populations living in middle-aged (1947 burn area) and recent (1969 burn area) burned forest stands on the Kenai Peninsula, Alaska, during 1982-87. Densities of bears on the 1947 (205 bears/1,000 km2" role="presentation" style="box-sizing: inherit; display: inline; font-style: normal; font-weight: normal; line-height: normal; font-size: 16px; text-indent: 0px; text-align: left; text-transform: none; letter-spacing: normal; word-spacing: normal; overflow-wrap: normal; white-space: nowrap; float: none; direction: ltr; max-width: none; max-height: none; min-width: 0px; min-height: 0px; border: 0px; padding: 0px; margin: 0px; position: relative;">205 bears/1,000 km2205 bears/1,000 km2) and 1969 (265 bears/1,000 km2" role="presentation" style="box-sizing: inherit; display: inline; font-style: normal; font-weight: normal; line-height: normal; font-size: 16px; text-indent: 0px; text-align: left; text-transform: none; letter-spacing: normal; word-spacing: normal; overflow-wrap: normal; white-space: nowrap; float: none; direction: ltr; max-width: none; max-height: none; min-width: 0px; min-height: 0px; border: 0px; padding: 0px; margin: 0px; position: relative;">265 bears/1,000 km2265 bears/1,000 km2) burn areas were similar. Sex ratios of the 2 populations were not different (P = 0.478), but there were significantly more (P = 0.007) females than males in both areas. Age structures of the population were different (P = 0.003). There were more yearlings in the 1969 burn area due to higher cub production and survival. Female bears in the 1947 burn bred at a later age (P = 0.03) (5.8 yrs) than females in the 1969 burn (4.6 yrs). Females in the 1947 burn also had a longer interval between successful weaning of yearlings (P = 0.03) (2.4 yrs) than females in the 1969 burn (2.0 yrs). Weights of adult females and yearlings in the 1947 burn area were significantly less (P < 0.001) than those in the 1969 burn area. Food habits and food abundance in the 2 areas were similar except that bears in the 1947 burn area consumed more lowbush cranberry (Vaccinium vitis-idaea) and bears in the 1969 burn area consumed approximately 4 times more moose calves (Alces alces) per individual. Most bears in both areas migrated each summer from their traditional use areas to old-growth forest where they consumed American devilsclub (Oplopanax horridus) fruit. Timing of migration and length of stay in American devilsclub stands were related to fruit abundance. Estimates of survival using the Kaplan-Meier procedure were significantly lower (P = 0.05) for cubs in the 1947 burn (0.74) than in the 1969 burn (0.91) but higher for subadult females in the 1947 burn. Survival was not different for all other age and sex classes of bears. Human, primarily hunters, caused 85% of the deaths (n = 35) in the 1969 burn, but only 52% (n = 31) in the 1947 burn, where there also was significant mortality from black bears (13%) and brown bears (U. arctos) (10%). Vigor of black bears was linked to moose abundance. The superior growth and reproduction of black bears in the 1969 burn was attributed to a greater consumption of moose calves. Our findings demonstrated a link between neonatal predation and demographics of bear populations.

Evidence for fatal injury inflicted on a female black bear by a moose
Abstract
Predators may risk injury or death when attacking large prey. Black bears (Ursus americanus) are known predators of young moose (Alces alces), which may be defended from predators by their mothers. We report evidence that a radio-collared adult female black bear was killed by a cow moose during a presumed predatory attack. This observation suggests that moose are dangerous prey for black bears.

BLACK BEARS WERE RESPONSIBLE FOR THE MASSIVE AND EARLY NEST PREDATION IN THE OKEFENOKEE SWAMP.
FOR A FEMALE ALLIGATOR AN ADULT BLACK BEAR IS A FORMIDABLE OPPONENT AND IF HER NEST DEFENSE REQUIRES CONTACT WITH THE BEAR SHE COULD BE INJURED.
THE BLACK BEAR WAS THE MAJOR PREDATOR ON THE ALLIGATOR NESTS THAT WERE STUDIED.

To be honest killing a wild hog or wild boar is impressive. These pigs have thick necks (as thick as their bodies) which means they are not easy to kill.

There is no easy way to kill pigs. Their thick necks (almost as thick as their bodies means they cannot be killed by strangulation).
