Wolf packs attack the toughest prey in Yellowstone. By Brett French. Billings Gazette Staff.
“It’s not easy being a bison-eating wolf in Yellowstone National Park.”
Mollies Pack has become a rugged bison-killing wolf pack. They are a pack ideal for this with their big brawny male wolves. It’s no accident. With elk, big males in a pack are superfluous as long as their is one big guy, but not so with bison. So the big males born to Mollies tend to stay with the pack and others sees to join it.
To some degree the Cougar Creek and Gibbon Meadows Pack have become bison killers too.
