Grizzly bears feed on fish such as salmon, trout, and bass. Bears with access to a more protein-enriched diet in coastal areas can grow larger than inland individuals, due to the richness of their diets. Inland grizzly bears' diet consists mostly of whitebark pine nuts, tubers, grasses, rodents, army cutworm moths and scavenged carcasses. None of these match the fat content of the salmon available to grizzly bears in Alaska and British Columbia.
