Hungry Yosemite bears zero in on minivans

The rebellious bears of Yosemite Valley have developed a taste for that old standard of the suburban family life, the minivan.
The kid-friendly vehicles are quickly becoming a bear necessity along with handouts and garbage slop, according to a study published in the October issue of the Journal of Mammalogy.
Specifically, the burly bruins select minivans over all other types of vehicles, no matter how sporty, colorful or expensive, and rip them open looking for grub, said the study "Selective Foraging for Anthropogenic Resources by Black Bears: Minivans in Yosemite National Park."
"They target minivans," said Stewart Breck, a research biologist with the National Wildlife Research Center, who co-authored the study. "They will pop open windows, peel open a door, rip out back seats. They can do a lot of damage."

It is all related to what Breck called "fuel efficiency." He means that minivans often contain goodies like smeared peanut butter, moldy cheese or, occasionally, ice chests full of groceries and beer that bears can use to fuel their opportunistic lifestyles.
"I think there are more food smells in minivans," Breck said. "Bears have very good noses. They are like bloodhounds, so they can smell food even when all the doors and windows are locked tight."
Besides chow, nobody knows for sure what the hairy oafs have in mind when they bear down on a parked vehicle, but structural considerations may also come into play, according to the study. Specifically, the rear side windows of minivans appear to be a snap for bears to pop open.
The study analyzed 908 vehicles in Yosemite National Park that black bears opened like soup cans between 2001 and 2007. Minivans were the first or second preference every year, accounting for 26 percent of all the break-ins. That's despite the fact that they make up only 7 percent of the vehicles parked in Yosemite Valley.
