PULLMAN, Wash. -

Washington State University has a grizzly at its Bear Research Education and Conservation Center that appears to be smarter than the average bear.

In a study of a bear's ability to use objects as tools, the center tested how its eight grizzly bears would use a sawed-off tree stump to reach a glazed doughnut hanging over their play area.

The Moscow-Pullman Daily News reports a bear named Kio wasn't stumped. The 9-year-old moved the stump into position so she could climb on it to reach the treat.
