Ursus arctos horribilis
Grizzly bears are large aggressive animals. Color varies from black to blond. Female grizzlies may weigh 150–350 kilograms (330–770 pounds), while males weigh 230–450 kilograms (510–990 pounds). The larger of these sizes are typically the coastal grizzlies, which have rich diet of salmon, while the smaller sized animals are interior grizzlies. There is, however, a great deal of size variation from region to region.
Today mostly mountain forests and alpine meadows, but formerly were found in grasslands as well.
I took this photograph in Yellowstone National Park very early one morning. This large bear, a boar known as Scarface for all the battles he's been in, was digging roots on the side of the road. The people in the background were far too close and had left their car to get a better look and in violation of a park rule that stipulates that you must not approach a bear within 100 yards. (I was in my car parked legally at a turnout when he showed up.) Fortunately, this grand old bear ignored everyone and went on with his business as if we weren't there.
