Critter Guide :: Mammals :: Grizzly Brown bears, also called grizzlies, are very large and powerful. They can weigh between 300 and 1,400 pounds and standing upright, can tower up to 8 feet. They are also fast and can run 35 miles per hour. Their coat color ranges from blonde to brown and black and the long outer guard hairs are often tipped with silver, giving it a grizzled appearance. Where do they live? American grizzlies live in Canada, Alaska, Montana, Idaho, Wyoming, and Washington. What do they eat? Grizzlies are omnivorous, eating nuts, berries, deer, fish, rodents, fruits, wild honey, grasses, herbs, and human food. Social Environment The most aggressive bear is the grizzly. Like most bears, grizzlies are loners with the exception of females with cubs. Critter Fact During the fall, a brown bear eats almost around the clock, stocking up for the 4 to 7 months when it'll have to live off stored body fat. A grizzly may eat 90 pounds of food each day. Did You Know? All grizzlies in the lower 48 states are listed as threatened under the Endangered Species Act. Today, they number around 1,000 (down from nearly 100,000 before the west was settled.) Loss of habitat is a main factor, since it is now 2 percent of what it once was. Protecting existing habitat and restoring degraded habitat can help the grizzly to recover.
