Maulings by Bears: What's Behind the Recent Attacks?

The recent bear attacks in North America over the past week are unrelated to one another and are not indicative of a trend, experts say.

At least six people in five states have been mauled by black and brown bears recently. The latest incident occurred on Saturday, when a hunter in the remote Alaskan wilderness was attacked by an alleged brown bear, also known as a grizzly bear, and survived more than 36 hours before being rescued by the state's air national guard.

Last Thursday, hikers in Yellowstone National Park in Wyoming were attacked by a female grizzly after they got too close to her cubs. One of the men was clawed and bitten on his backside.

Also on Thursday, 12-year-old Abigail Wetherell was attacked by a black bear while out on an evening jog in northern Michigan.

According to news reports, Wetherell initially tried to run away from the bear, but she was chased and knocked down. After trying to escape a second time and failing, she played dead. A neighbor who heard the girl scream eventually scared the animal away, but not before it slashed Wetherell's thigh.

Over the weekend, conservation officers shot and killed a black bear they believed to be the one that attacked Wetherell.

Bear expert John Beecham said it's unclear from the accounts he's read why the animal might have attacked the girl. "It might have been a female [bear] and she had young, or the girl might have just come up on the bear fairly quickly while running through the woods, and it perceived her as a threat and attacked," he said.
