Step aside. This wolf pack is chasing a deer that is running for its life behind where you are standing. The pair may pursue the deer for several miles to exhaust it, then bring it down in a joint effort. Group hunting is how wolves can prey on animals much bigger than themselves.
Still, deer are fast, and this one had a head start—the tracks on the right show its frightened flight. If the wolves cannot close in quickly, they will give up and follow the scent of another prospect. As is common for carnivores that chase after their prey, wolf hunts fail far more often than they succeed.
