Being omnivores, they feed on a variety of plants and berries including roots or sprouts and fungi as well as fish, insects and small mammals. Normally a solitary animal, the grizzly congregates alongside streams and rivers during the salmon spawn. Every other year females produce 1-4 young which are the size of rats, weighing only 1 pound. The prints of the grizzly bear are characterized by an oval pad with five toes along the wider top of the pad on the hind feet. The front feet have a smaller heel pad and a dew claw which may be present in the print.
Claw marks over twice as long as the toe pads are usually evident.
