Originally posted by RobG Nice! I've been to North America several times but so far I haven't seen a bear in the wild. In Yellowstone we saw Elk and Bison. Mind you, I was glad I never had to follow the instructions of the park rangers at Mount Ranier for a close up bear encounter; "If you come around a corner and there's a bear you can't back away from, drop on the ground, curl up in a ball and wait. The bear may come up and poke at you - if you make any noise, he might decide you're fun to play with..."
I've seen first-hand evidence of bears in Yosemite - a car with the rear passenger window broken and the metal frame folded against the side of the car. Someone ignored the warning not to leave food in their car...
PS Looks like the adult is wearing a tracking collar.
I wouldn't worry too much about American black bears. Every black bear I've encountered while on foot has run away (except at garbage dumps and in Canada's national parks before the mid-1970s when they had poor waste management). However, Steve Herrero's (University of Calgary) examinations of bear attack data reveals an exception to that rule. Fatal black bear attacks involve large male bears that have had no prior contact with people, and these attacks are acts of predation on lone, small people (small women or children). I`m an adult male who is average-sized for a man of European descent. The oft told warning that a sow with a cub will attack is largely a myth. They will make noise and charge, but rarely make physical contact. Brown bears in North America (grizzlies), on the other hand, are larger and are less predictable. If they do attack, it may be an act of territoriality or predation. Polar bears, which are bigger yet, are quite predictable. They will try to make a meal of you. I`ve never had the opportunity to test these predictions for grizzlies and polar bears in-person, although I`ve seen plenty from aircraft and ships.
