Interesting fact:

The advice differs depending on whether you are dealing with a grizzly bear or a black bear, but there are some blanket rules. The National Park Service reminds us that bears are often just as scared of humans as we are of them, and they are much more likely to be defensive if they have cubs around. Moreover, you can try shouting ‘get out of here, bear’ to the easily spooked black bear, but this isn’t such a good idea with a grizzly.
