This video from the USA is about grizzly bears versus wolves.
From Associated Press:
1st grizzly seen at Elk Refuge in nearly 20 years
August 27, 2013 4:00 pm
A sow, with three cubs, was seen on Aug. 20 feeding on a gut pile from the annual bison hunt. It’s believed to have been a bear well-known to visitors of Grand Teton National Park, No. 399. That bear had triplets this year and had been seen in the southeast edge of the national park days before the refuge sighting.
A grizzly, also with three cubs, was last seen at the refuge in 1994.
