There’s actually an interesting statistic where bear attacks from black bears are more likely to happen from the males, whereas attacks from grizzlies are more likely to happen from the females.

Black bear cubs have a strategy to run up the nearest tree when threatened and the mama bear guards the base of the tree rather than going on the offensive, so you are able to back away and avoid an attack a lot easier than a female grizzly, since grizzly cubs don’t instinctually climb trees when threatened but inside rely on the mother to defend them by going on the offensive.
