Thanks for all the replies guys.
I read in an old Elmer Keith article that says (according to him) that Grizzlies don't eat people but black bears do, but it seems that Grizzlies do eat people from time to time.
It makes me glad that we have no bears in Australia. We have sharks, snakes, spiders, crocodiles, dingoes, wild dogs, buffalo, scrub Bulls, jellyfish and scorpions... but no bears!
The theory is that blacks attack for food but grizzlies attack to defend cubs or territory. That's the theory and while it might be generally correct, it's nowhere near 100% correct.
