A chocolate Brown Grizzly enjoying some grass and grubs near a small vent geyser on the east banks of Yellowstone Lake. Grizzlies are omnivores , which means they eat grass,berries,as well as protein(animals,grubs) unlike their cousins the Alaskan Brown Bears which eat mainly salmon(protein) which is why they are nearly twice the size of the interior grizzly ..a lot of the early food a grizzly will eat when they come out of hibernation is berries,grasses etc. Now, you only have to ask yourself one question..Can you run faster than 35mph??? HE CAN...
