when did grizzly bears become extinct in california?
in 1924
less than 75 years after the discovery of gold in 1848, almost every grizzly bear in california had been tracked down and killed. one prospector in southern california, william f. holcomb (nicknamed "grizzly bill" holcomb), was particularly well known for hunting grizzly bears in what is now san bernardino county. the last hunted california grizzly bear was shot in tulare county, california, in august 1922, although no body, skeleton or pelt was ever produced. two years later in 1924, what was thought to be a grizzly was spotted in sequoia national park for the last time and thereafter, grizzlies were never seen again in california.

meat, as already described, is an important part of a grizzly's diet. grizzly bears occasionally prey on small mammals, such as marmots, ground squirrels, lemmings, and voles. the most famous example of such predation is in denali national park and preserve, where grizzlies chase, pounce on, and dig up arctic ground squirrels to eat. in some areas, grizzly bears prey on hoary marmots, overturning rocks to reach them, and in some cases preying on them when they are in hibernation. larger prey includes bison and moose, which are sometimes taken by bears in yellowstone national park. because bison and moose are dangerous prey, grizzlies usually use cover to stalk them and/or pick off weak individuals or calves. grizzlies in alaska also regularly prey on moose calves, which in denali national park may be their main source of meat. in fact, grizzly bears are such important predators of moose and elk calves in alaska and in yellowstone, that they may kill as many as 51 percent of elk or moose calves born that year. grizzly bears have also been blamed in the decline of elk in yellowstone national park when the actual predators were thought to be gray wolves. in northern alaska, grizzlies are a significant predator of caribou, mostly taking sick or old individuals or calves. several studies show that grizzly bears may follow the caribou herds year-round in order to maintain their food supply. in northern alaska, grizzly bears often encounter muskox. despite the fact that muskox do not usually occur in grizzly habitat and that they are bigger and more powerful than caribou, predation on muskox by grizzlies has been recorded.
