Bears at WSU snoozing away, as hibernation deepens.

Posted by Lynda V. Mapes

Reports Charlie Robbins , director of Bear Center at Washington State University, all twelve grizzlies are snoozing away until March, and they have been in hibernation since about late October. "It's a great weight loss program," he notes, as the bears live off the fat they put on just before entering their dens for the winter -- some nine to ten pounds per day.
But once they turn the light out in the dens, it's night-night until March -- which right about now can seem like a pretty good idea.
