Grizzly bear vs wolf. Pack of wolves attacking grizzly bear with cubs - what will be outcome? The grizzly bear, less commonly known as the silvertip bear, is a large subspecies of brown bear inhabiting North America. The grizzly bear is, by nature, a long-living animal. The average lifespan for a male is estimated at 22 years, with that of a female being slightly longer at 26. Females live longer than males due to their less dangerous life; avoiding the seasonal breeding fights in which males engage. The oldest wild inland grizzly was 34 years old in Alaska; the oldest coastal bear was 39, but most grizzlies die in their first few years of life from predation or hunting. Captive grizzlies have lived as long as 44 years. Grizzlies are considered more aggressive compared to black bears when defending themselves and their offspring. Unlike the smaller black bears, adult grizzlies do not climb trees well and respond to danger by standing their ground and warding off their attackers. Mothers defending cubs are the most prone to attacking, and are responsible for 70% of humans killed by grizzlies. A sign at a BC Park warns campers to hang food, garbage, and toiletries out of reach of bears, or to use a secure bear cache. Grizzly bears normally avoid contact with people. In spite of their obvious physical advantage they rarely actively hunt humans. Most grizzly bear attacks result from a bear that has been surprised at very close range, especially if it has a supply of food to protect, or female grizzlies protecting their offspring. Increased human–bear interaction has created "problem bears": bears adapted to human activities or habitat. Aversive conditioning using rubber bullets, foul-tasting chemicals, or acoustic deterrent devices attempt to condition bears to associate humans with unpleasantness, but is ineffectual when bears have already learned to positively associate humans with food. Such bears are translocated or killed because they pose a threat to humans. The B.C. government kills approximately 50 problem bears each year and overall spends more than one million dollars annually to address bear complaints, relocate bears and kill them. Grizzly bears are especially dangerous because of the force of their bite, which has been measured at over 8 megapascals (1160 psi). It has been estimated that a bite from a grizzly could even crush a bowling ball. The gray wolf or grey wolf, also known as the timber wolf or western wolf, is a canine native to the wilderness and remote areas of Eurasia and North America. It is the largest extant member of its family, with males averaging 43–45 kg (95–99 lb), and females 36–38.5 kg (79–85 lb). Like the red wolf, it is distinguished from other Canis species by its larger size and less pointed features, particularly on the ears and muzzle. Its winter fur is long and bushy, and predominantly a mottled gray in color, although nearly pure white, red, or brown to black also occur. The gray wolf is the second most specialised member of the genus Canis, after the Ethiopian wolf, as demonstrated by its morphological adaptations to hunting large prey, its more gregarious nature, and its highly advanced expressive behavior. It is nonetheless closely related enough to smaller Canis species, such as the eastern wolf, coyote, and golden jackal to produce fertile hybrids. It is the only species of Canis to have a range encompassing both the Old and New Worlds, and originated in Eurasia during the Pleistocene, colonizing North America on at least three separate occasions during the Rancholabrean. It is a social animal, travelling in nuclear families consisting of a mated pair, accompanied by the pair's adult offspring. The gray wolf is typically an apex predator throughout its range, with only humans and tigers posing a serious threat to it. It feeds primarily on large ungulates, though it also eats smaller animals, livestock, carrion, and garbage. The gray wolf is one of the world's best known and well researched animals, with probably more books written about it than any other wildlife species.
