I am far more fearful of black bears than grizzly/brown bears. A black bear will consider a human as prey and actively chase/climb after a human and eat s/he. They can climb quite well. They also account for a lot of pets, mostly dogs, going missing. Two cases: A couple was living in a cabin on the mainland off in the woods when a blackie showed up and behaved aggressively. The wife had managed to climb to the roof of the cabin, while the husband managed to get to the skiff and went for help. Upon his return, with backup, the remains of his wife were found, with the blackie working on finishing her off. My eldest daughter, who at the time was 14 years old, was spending some time with her best friend at her best friend’s grandparents house in a suburb of Anchorage. The girls watched as a black bear came out of the woods and made a meal of one of the grandparents dogs during the middle of the afternoon.
I can’t speak on grizzlies with as much authority, even though they and Kodiak bears are the same beast. Kodiaks live on, well, Kodiak, and grizzlies are sometimes coastal, but often live inland. Grizzlies are smaller than Kodiak’s, but I would imagine they behave much the same.
I know Kodiak bears, up close and personal. Pepper spray is for defense against people, IME. In the heat of the moment one isn’t apt to check for wind direction, and a face full of pepper spray is not going to help you out of a Kodiak encounter. Unless you have a mighty big weapon and are a very good shot, a gun isn’t going to help you. I have been around when nuisance bears have been shot, they don’t die easily. Their skulls are incredibly thick, don’t shoot them in the head, it only serves to piss them off. For the most part a Kodiak wants nothing to do with people, and we make a lot of noise when we are out, because a startled bear is not a happy bear. In one instance in particular my husband shooting off his 270 into the air had absolutely no effect on the sow and two cubs in our back yard. When I leaned out the window, beating my frying pans against each other and screaming my head off they jumped and ran. That always worked the best.
If you run into a bear, give the bear the right of way. If the bear makes a charge (generally they will make a couple/few false charges) make yourself as large as possible and holler at the bear. After a couple of feints, generally the bear will wander off. If you are attacked, drop and curl into the fetal position, covering as much of your abdomen as possible with your knees/legs and link your fingers together to cover the back of your neck. Maybe the bear will become disinterested, but more likely the bear will still take a couple of bites for a snack, and then may drag you off and bury you in a shallow depression. Do Not Move, and Don’t Make A Sound until the bear has moved on. This may take a bit of time, and if you move or make noise the bear will probably come back and make sure you are really dead. Kodiaks like their meat to tenderize a bit, and will leave cached carrion for a later meal. If you wait it out, you may get out alive.
However, for the better part, Kodiaks don’t want to bother with humans. I live in bear country, and spent time in the Bush where I saw bears up close and personal on an almost daily basis. Kodiaks don’t hibernate, they den up during cold storms, but there are always a few wandering around. Mostly bears who didn’t get enough food before the salmon quit running and have become garbage bears. These are the bears to worry about. They break into smokehouses, raid dried fish racks, and frequently bust into homes. These are the bears which are put down. I recall one bear in particular, big old boar who had been knocking over smokehouses and breaking people’s doors, and generally becoming very bold and aggressive. The night they took him out was memorable in that there were at least five men, armed with large calibre semiautomatic rifles, and when they began firing it sounded like a war. The guns were rattling away, gun smoke in the air, and the roars and thrashings of the old bear made a fearful racket. It took at least 15 minutes, more like 25, before the bear became still. The next morning I walked around the bend in the road where the bear was killed, and it looked as if there had been a war. Bushes and small trees were uprooted and flung around, the ground itself was torn to hell, and the guy who Fish And Wildlife had given to okay to take out nuisance bears was already out and skinning the bear. He had already detached the head, and I don’t think I could have wrapped my arms around it, it was a huge bear. (When a bear is killed In Defense of Life and/or Property it must be skinned, and decapitated, with the hide and head going to Fish and Wildlife to be sealed, in order to avoid poachers)
Timothy “Idiot” Treadwell got what was coming to him, he broke the rules. It’s too bad that the girlfriend had to die as well, but Tim was a meal waiting to happen. If you watch Herzog’s documentary, when Tim went back to his camp all the bears who were familiarized with him had headed for higher ground. The old boar, Oly, who ate him was hungry, the fish had quit running, and you can see the bear sizing Tim up. He wasn’t going to survive the winter, and he did what starving bears do.
I do not fear bears. I do respect them. It pisses me of righteously when some idiot causes the death of an otherwise normal bear doing it’s bear thing.
Sorry for the length, I have lots of bear stories, and feel strongly that it’s best to live and let live whenever possible. Just for an example of size, here is a now deceased bear guide I knew, his grandson is my son’s godfather. This is a fairly average size Kodiak bear, just for reference. I would guess his original height at ten feet+. http://i33.photobucket.com/albums/d79/kaiwik/P_AlexAndBear.jpg
