Ursus arctos horribilis

Also known as North American Brown Bear, Silvertip Bear

Grizzly bears are solitary, powerful omnivores distinguished by a prominent shoulder hump of muscle that powers their front legs for digging. Range boundaries extend across western Canada, Alaska, and select pockets of the northwestern United States, where individuals traverse vast territories searching for seasonal food surges. Sows raise their cubs for up to three years, defending them fiercely against adult males and other environmental threats.
