Though once abundant over much of North America and Eurasia, the grey wolf inhabits a very small portion of its former range because of widespread destruction of its habitat; in some regions it is endangered or threatened. Considered as a whole, however, the grey wolf is regarded as of least concern for extinction according to the International Union for the Conservation of Nature and Natural Resources. Wolf weight and size can vary greatly worldwide, tending to increase proportionally with latitude as predicted by Bergmann's Rule. Wolves are usually hunted in heavy brush and are considered especially challenging to hunt, because of their elusive nature and sharp senses. Grey wolves are notoriously shy and difficult to kill, having been stated to be almost as hard to stalk as cougars, and being far more problematic to dispatch with poison, traps or hounds. However, wolves generally do not defend themselves as effectively as cougars or bears. Some wolves will evade capture for very long periods of time and display great cunning. One specimen nicknamed "Three Toes of Harding County" in South Dakota eluded its pursuers for 13 years before finally being caught. Another wolf nicknamed "Rags the digger" near Meeker, Colorado would deliberately ruin trap lines by digging up traps without tripping them. In sport hunting, wolves are usually taken in late autumn and early winter, when their pelts are of the highest quality and because the heavy snow makes it easier for the wolves to be tracked. Adult wolves are usually too fast to be overtaken by wolfhounds, but not for well conditioned horses, especially in thick snow. A shot wolf must be approached with caution, as some wolves will play possum. Accounts as to how wolves react to being trapped or cornered vary. John James Audubon wrote that young wolves typically show little resistance to being caught, whereas older, more experienced wolves will fight savagely. Pelts Wolves are commonly hunted for their fur. The color of a wolf's fur can vary, from the pure white of the largest, Alaskan wolves, through the range of reddish brown. Even the so-called "grey wolves" can include pure black pups in a litter, although grey is the most common color. Wolves have two kinds of hairs; an outer coat of long, stiff hairs called "guard
