1. Grizzlies generally have a hump.
2. Grizzlies have a dished (Labrador retriever) face while a black bear has a
straight profiled (Doberman pincher) face.
3. The track of the grizzly shows the toes to be on a straight line while a
black bear slants at an angle.
4. Grizzlies are generally a tri colored animal, however color is not a good
way to judge between a grizzly and black bear. Black bears can be black, brown
or cinnamon colored.
Generally a grizzly is more aggressive in nature, however it is not uncommon
for a black bear to go into predacious mode in which they may size up a human
for food.
