grizzly, black bear hybrid

[88] Also extremely important in fall are berries such as huckleberries and buffalo berries. It needs to be carefully removed from the box and allowed to expand for a day or so. The metabolic rate of a hibernating bear will remain at a reduced level for up to 21 days after hibernation. [7], The ancestors of American black bears and Asian black bears diverged from sun bears 4.58 mya. Understanding the physiology of bears in the wild is vital to the bear's success in captivity. [123] Another exceptional attack occurred in August 1997 in Liard River Hot Springs Provincial Park in Canada, when an emaciated American black bear attacked a mother and child, killing the mother and a man who intervened. In eight states, only a big game license is required to hunt American black bears. The bear was shot while mauling a fourth victim. They typically open their eyes after 28–40 days and begin walking after five weeks. [135] In the western states, where there are large American black bear populations, there are spring and year-round seasons. However, both Arctodus and Tremarctos had survived several other, previous ice ages. [81] The bear keeping track of the changing days allows it to awaken from hibernation at the appropriate time of year to conserve as much energy as possible. Bear hunting had been banned in New Jersey for five years before that time. DNA testing of a bear found near Sachs Harbour, Northwest Territories on Banks Island, found the bear was indeed a hybrid of two species. At the age of six weeks, they attain 900 g (2.0 lb), by the age of eight weeks they reach 2.5 kg (5.5 lb) and by the age of six months they weigh 18 to 27 kg (40 to 60 lb). Hybrids of several combinations of bear species have long been bred in zoos, including black bear-brown bear, brown-grizzly, and brown-polar. Also, there has been a case of a female Asian black bear breeding with a male brown bear. [71] The breeding period usually occurs in the June–July period, though it can extend to August in the species' northern range. [104] There is at least one record of a male American black bear killing two bull elk over the course of six days by chasing them into deep snow banks, which impeded their movements. [75] Flooding of dens after birth may also occasionally kill newborn cubs.

Distinguished by its fur being silvery-gray with a blue luster found mostly on its flanks. In this region, bears occasionally move to more open areas to feed on prickly pear cactus. Unlike female brown bears, female American black bears are not as protective of their cubs and rarely attack humans in the vicinity of the cubs. [90], Generally, American black bears are largely crepuscular in foraging activity, though they may actively feed at any time. [80], During their time in hibernation, an American black bear's heart rate drops from 40 to 50 beats per minute to 8 beats per minute and the metabolic rate can drop to a quarter of the bear's (nonhibernating) basal metabolic rate (BMR). Along the Pacific coast, redwood, Sitka spruce and hemlocks predominate as overstory cover. They reach sexual maturity at the age of three years and attain their full growth at the age of five years. Compared to brown bear attacks, aggressive encounters with American black bears rarely lead to serious injury. A bear in pursuit of a pet dog can threaten both canid and human lives. Black Bear Woman's children, in turn, killed Grizzly Bear Woman's children. The hunter had bought a license to hunt polar bears; he did not have a license to hunt grizzly at that time.[8]. [95][96][97] Bears may catch the scent of hiding fawns when foraging for something else and then sniff them out and pounce on them. American black bear meat had historically been held in high esteem among North America's indigenous people and colonists. Although they occasionally hunt adult cattle and horses, they seem to prefer smaller prey such as sheep, goats, pigs and young calves. Canadian black bear hunts take place in the fall and spring and both male and female bears can be legally taken, though some provinces prohibit the hunting of females with cubs, or yearling specimens. [5][page needed] American black bears living in areas near human settlements or around a considerable influx of recreational human activity often come to rely on foods inadvertently provided by humans, especially during summertime. [5][page needed] Prior to that time, they can put on up to 14 kg (30 lb) of body fat to get them through the several months during which they fast. The number of attacks on humans is higher than those by brown bears in North America, but this is largely because black bears considerably outnumber brown bears. The animal had dark rings around its eyes, similar to a panda's, but not as wide. "This bear has a black nose, and normal dark-coloured eyes and claws. Unlike the hunting of hibernating grizzly bears, which was fraught with danger, hibernating American black bears took longer to awaken and hunting them was thus safer and easier. [citation needed], Game animals and shooting in North America, Lisette Waits, David Paetkau, and Curtis Strobeck, "Overview" from, McLellan, B. N. (2011). [citation needed], Grizzly bears have been sighted in what is usually polar bear territory in the Western Arctic near the Beaufort Sea, Banks Island, Victoria Island, and Melville Island. [8], The American black bear lived during the same period as the giant and lesser short-faced bears (Arctodus simus and A. pristinus, respectively) and the Florida spectacled bear (Tremarctos floridanus).
