HUNTING -- An 11-year old male grizzly bear was killed by black bear hunters near Yellowstone National Park on Wednesday, May 7, according to the Idaho Fish and Game Department.

The incident occurred on the Caribou-Targhee Forest, just off of the Cave Falls Road in Idaho.  Both black bears and grizzly bears are known to frequent the area just outside of the southwest corner of Yellowstone National Park.

The incident is under investigation and information will be released as it becomes available, said IDFG, which is assisting the U. S. Fish & Wildlife Service with the investigation.

Hunters are responsible for sharpening their bear ID skills.

Educational info and a bear ID quiz -- this can be humbling -- is available on the Idaho Fish and Game website.
