Food is so hard to find in this far north that a wolf pack must search 100s of km^2 if it's to be successful. And success means raising the next generations. To do that, here, the wolves must work together. So the young are raised not only by their parents, but by their aunts and their uncles as well. Together, they try to ensure that each pup reaches near adult size before the snow returns. A growing pup needs more than just a few leverets. The wolves need bigger prey, and to catch that, they must hunt as a pack. Adult hares may be easy to spot, but they are far from easy to catch. They run at 60km/h. To catch one, the wolves work as a team. One of them gets close enough to bite the hare's tail, but the hare can change direction in an instant. If it could continue to sidestep and jink, it may ultimately outlast them. Finally it gets away. For the next hare, the whole pack gives chase. Now numbers count. The lead wolves keep up the pace, others run on either sides so the hare can't change direction. A tiny meal for the whole pack.
A young fox on these barren wastes may have to travel 100 km a day, serching for food. Scratching for scraps and scavenging from others; it's a meager existence. And the worst of the winter is still to come. By midwinter, temperatures drop to minus 50 degrees Celsius, and deep snow makes scavenging nearly impossible. But a faint sound beneath the snow may be this fox's salvation; Lemmings. It's time to become a hunter. But catching what you can't see is not easy. It's hard to judge the leap, and the depth of the snow. Too deep, and you get stuck. Too shallow, and it can be rather painful. It's going to take time, but mastering lemming hunting is vital if a young fox is to make it through the winter. At last, this fox is on his way. But if he is to survive until spring, he'll need to make a catch like this every couple of days.
