After returning from Axel Heiberg Island, Brutus and probably his pack spent most of their time in the south end of their territory. In several places, 2 consecutive locations were the same, possibly representing kills.
Certainly a pack this size will have to be making kills frequently. How they do that in the 24 hours of darkness is a good question that we wish we could answer. The fact that the pack is spending so much time in the south end of its territory implies that many muskoxen may be spending their winter there too.
Just as wolf movements and activity at this time of year are unknown, so too are the movements and behavior of their shaggy prey. Hopefully we can draw some inference about muskox distribution during winter from examining the locations of the wolves.
