Picture of a Grizzly Bear Grizzly!

The grizzly bear lives in the uplands of western North America.

Grizzly bears reach weights of 180-680 kilograms (400-1,500 pounds). Their coloring ranges widely across geographic areas, from blond to deep brown or black. These differences, once attributed to subspeciation, are now thought to be primarily due to the different environments these bears inhabit, particularly with regard to diet and temperature.

The grizzly has a large hump over the shoulders which is a muscle mass used to power the forelimbs in digging. The head is large and round with a concave facial profile. In spite of their massive size, these bears can run at speeds of up to fifty-five kilometers per hour (thirty-five miles per hour).

Normally a solitary nocturnally active animal, in coastal areas the grizzly congregates alongside streams and rivers during the salmon spawn. Every other year females produce one to four young (most commonly two) which are small and weigh only about 500 grams (one pound).

The current range of the grizzly bear extends from Alaska, south through much of Western Canada, and into portions of the Northwestern United States.
