Portrayed throughout history as a villainous critter that wastefully kills, the wolf's reputation precedes it. The traditional image, however, is unwarranted and incorrect. Wolves are highly intelligent social animals. They are a critically important predator in the Western food chain. When wolves eat, so too do a host of other animals including wolverines, lynx, bobcats, mink, weasels, hares, porcupines, squirrels, mice, voles, shrews and ravens.

!ADVERTISEMENT!Wolves’ ancestry dates back to about 15 million years ago. They are related to foxes and domesticated dogs. There are two species in North America, the gray or timber wolf, and the red wolf. Wolves have the largest natural range of any animal on our continent and their main predator is human beings. Hence, they have been hunted and poisoned, at one point to near extinction. Thankfully, they are survivors.
The translation of the wolf's Latin name is literally "dog wolf," and for good reason. Wolves and dogs share common features. They both have a similar gestation time of about two months. And they both molt in the spring and grow winter coats in response to season differences in temperatures.
Wolves, however, do have distinct features. Their ears are relatively shorter, broad at the base and less pointy at the tip than those of most dogs. They have large heads with wide and heavy skulls that curve downward and blend into a broad but tapering muzzle that ends with a black nose. Their jaws have tremendous biting power.
They have longer legs than most dogs, with paws that are longer and wider in the front compared to the back. They have five frontal and four back toes. The fifth frontal toe is actually called a dewclaw and is used to help secure, hold and bring down prey. Because they are not necessary for locomotion, many dog owners have dewclaws removed. Big springy feet assist wolves in attaining a top end speed of about 40 mph (65 kph). More usually though, they travel at 5 to 6 mph (8 to 10 kph) while tracking prey for hours on end.
Wolves are large critters, ranging in size from 5 to 6 feet in length with an average weight of 88 pounds. Females are about 15 percent smaller than males.
One of the most remarkable aspects about wild animals, particularly in North Country, is how they manage with cold winter temperatures. It has to do with their winter coats. Wolves have an exquisite, two-layered coat. The outer layer consists of guard hairs that shed moisture, keeping the coat free of dirt and burs because of the hard, smooth, slippery hairs. Their thick underfur contains an oily substance similar to sheep's lanolin, helping make it impermeable to cold temperatures.
