I lose 10 times as much fur to fox, lynx and wolves as I do to wolverines. Nor has a wolverine ever bothered one of our cabins, much less actually entered and trashed one. Only once did we lose a bunch of cached fish, and that time I found tracks of wolves, marten and ravens as well as wolverines dotting the yard, so I could not say who the culprit really was. While wolves are making a comeback in some areas, to my knowledge, wolverines are not. Yet in Canada and Alaska where enough wilderness remains to support their wide-ranging habits, they are doing well even when trapped every winter.
Wolverines do, however, deserve their reputation for being fierce, even vicious animals.
They can sometimes even drive a wolf pack or bear from a kill, and, when trapped and confronted, their snorting, snarling threats must be taken seriously. Not even bears or wolves have a skull as highly adapted for crushing as a wolverine. Most carnivores have a fairly loosely hinged jaw with a joint that separates from the skull easily, but a wolverine jaw fits in the skull so tightly that you can hardly pull it apart. This suits his lifestyle well. In addition to hunting small animals, newborn big game and occasionally larger animals, especially if sick or injured, wolverines are scavengers.
