The grey wolves are the largest canines of them all!Grey wolves are social animals and hunt and live in packs from two to twelve.If a subordinate wolf feels a strong inclination to breed, and his/her attempts to mate are denied by the alpha pair, the subordinate wolf may leave the pack. However, leaving the safety of the group can prove to be a dangerous choice for the lone wolf, who may have to travel hundreds of miles to find a new territory and mate.
Gray wolves are known as keystone predators because they help maintain a balanced ecosystem. Their diet consists of ungulates (large hoofed mammals) such as elk, deer, moose, and caribou, as well as smaller mammals like beavers and rabbits. Because gray wolves eliminate only weak animals, herds become stronger and healthier as a whole. In fact, studies have shown that gray wolves have helped prevent the spread of chronic wasting disease, a contagious neurological disease, in deer.Playing a major character in fairy tales and mythology throughout the ages, the gray wolf (or timber wolf) has been perceived in many different lights, from “Big, Bad Wolf” to spiritual being. In reality, gray wolves may not embody such extreme vices and virtues, but they do play a vital role in maintaining ecological harmony.
