Predatory attacks by black bears happen more frequently than with Griz/Brown. But there are far more blacks than griz, so i don't know what the bear per capita attack ratio really is. Plus blacks have a far wider distribution range with far closer proximity to humans.
Attacks by either are very rare, considering. For every bear/human contact the person is aware of, there are likely 10 or more that only the bear is aware of.
Bearanoia is way overblown.
That's why I am almost always heeled "out there".
