interesting
There is a filmed account of one pack taking over another packs territory. It was one heck of a battle. One interesting side note, the pack that lost the territory had tolerated these two foxes, letting them eat from the carcass after they were full. When the new pack took over the foxes thought they would have the same privilages. They let them come into the carcass and then as if on cue attacked, one made it, one was a snack. I'll see if I can find it. Well I looked and can't find the production, I'm pretty sure it was a fight between the Druids and the Slough wolf packs in Yellowstone.
