The grizzly bear (Ursus arctos horribilis), also known as the silvertip bear, is a subspecies of brown bear (Ursus arctos) that lives in the uplands of western North America.

Normally a solitary active animal, in coastal areas the grizzly congregates alongside streams, lakes, and rivers during the salmon spawn. Every other year females, (sows) produce one to four young (most commonly two) which are small and weigh only about 500 grams (one pound). Sows are very protective of their offspring, and will attack the predator, if the female Grizzly thinks it's being threatend.
