1Food is so hard to find this far north that a wolf pack must search hundreds of square kilometres if it's to be successful...
2and success means raising the next generation.
3To do that here, the wolves must work together.
4So, the young are raised not only by their parents...
5but by their aunts and uncles as well.
6Together, they try to ensure that each pup reaches near-adult size before the snow returns.
7A growing pup needs more than just a few leverets.
8The wolves need bigger prey and, to catch that...
9they must hunt as a pack.
10Adult hares may be easy to spot...
11but they are far from easy to catch.
12They run at 60 kilometres an hour.
13To catch one, the wolves work as a team.
14...
15One of them gets close enough to bite the hare's tail.
16But a hare can change direction in an instant.
17If it can continue to sidestep and jink, it may ultimately outlast them.
18...
19Finally, it gets away.
20...
21For the next hare, the whole pack gives chase.
22...
23Now, numbers count.
24The lead wolves keep up the pace.
25Others run on either side, so the hare can't change direction.
26A tiny meal for a whole pack.
