1. In April of 06, I was talking about bears with a British Columbia guide who claimed that grizzlies attack humans for territorial reasons, but that black bears do it as a means of obtaining dinner, and will actually stalk a choice two-legged morsel as does a puma. I'd never heard this before, but today, I saw the same information in Jeff Cooper's Gunsite Gossip. So it must be true. However, I'm certain that the brown bear who nailed Timothy Treadwell was simply irritated beyond endurance.
