Brown Bear Claw Marks
This photo shows the claw marks made by a Brown Bear Ursus arctos on a tree. Bears probably do this for several reasons including making a visual, territorial sign for other bears to notice. At the same time a little "comfort behaviour" that is, claw cleaning or sharpening, may be involved. Photo taken in the Bieszczady Mountains, Poland, November 2008.
