Status description The grizzly bear is listed as threatened in the contiguous United States, and endangered in parts of Canada. In May 2002, the Canadian Species at Risk Act listed the Prairie population (Alberta, Saskatchewan and Manitoba range) of grizzly bears as being extirpated in Canada. In Alaska and parts of Canada however, the grizzly is still legally shot for sport by hunters. On January 9, 2006, the US Fish and Wildlife Service proposed to remove Yellowstone grizzlies from the list of threatened and protected species. In March 2007, the U.S. Fish and Wildlife Service "de-listed"the population, effectively removing Endangered Species Act protections for grizzlies in the Yellowstone National Park area.
Diet Even thought grizzly bears are listed as carnivora, they are indeed omnivores. They eat insects, wild honey, grasses, roots, berries, fish, rodents, moose, elks, deer, sheep, and sometimes other bears.

Around 85% of their diet is green vegetation, nuts, berries, insects and roots. They do eat some meat mainly elk, moose or deer. In Alaska, Salmon is a big part of their diet.
Physical description Grizzlies range in color from brown, black shades thereof to white and even blonde in rare circumstances. For most, fur tips are lighter in color which gives them a grizzled effect.

The toes are nearly in a straight line in a track and fall close together. The front tracks of brown bears reach 6-8 inches of length and 7-9 inches of width.

Grizzly bears hibernate in the winter usually 5 to 6 months. They live off their accumulated fat and don't eat during hibernation.

Grizzlies can run with a speed of over 60 km/h. The legs before and the shoulders of the grizzly are particularly massive and powerful and allow him to dig.
Size Males reach their maximum weight of 330 to 1150 pounds by 12 years; females reach their maximum weight of 270 to 770 pounds by 8 years.
Life span They generally live around 30 years.
Reproduction Female Grizzlies have 1 to 3 cubs every 3 years or so. The cubs will stay with the mother for 2 to 3 years. They reach sexual maturity at 4 and 5 years. They are considered fully grown by 8 to 10 years.
