PULLMAN, Wash. -- In a first-ever study, researchers at Washington State University are examining whether grizzly bears make and use tools.

According to researchers, information received from the study can be used to help wildlife managers better solve grizzly-related challenges and problems.

It can also assist zookeepers in keeping captive bears mentally and physically stimulated.

"While it's generally accepted that grizzly bears are intelligent creatures, until now no scientific research had been conducted on their problem-solving skills," said WSU veterinary biologist Lynne Nelson, who is overseeing the study.

The study, being conducted at WSU's Bear Research Education and Conservation Center, is documenting eight grizzlies faced with the challenge of getting their claws into a dangling food snack that's too high to reach. No training is involved.
