WILDLIFE -- Living on the Edge: Tara Canyon

Over the centuries, the emerald green Tara River in Montenegro on the Balkan Peninsula has etched a canyon 1,300 meters deep. The views throughout the Tara Canyon are spectacular. Up to 700 varieties of plants blanket its undulating hills. Herds of chamois live on the steep slopes where no human can venture. They nimbly roam the rocky cliffs, in perpetual danger of falling. Golden eagles circle imperiously overhead, waiting for the chance to strike. Living on the Edge chronicles a year in the life of the magnificent Tara Canyon featuring an up-close look at the chamois that live there.
