Gray Wolf. The gray or timber wolf's story is one of the most compelling tales of American wildlife. Once, the wolf was widespread across most of North America, but it was hunted ruthlessly and extirpated over most of its range. Today, the wolf is making a successful comeback in some of its former habitat due to strong conservation efforts.
They are also one of most widespread land mammals, inhabiting various ecosystems throughout North America, Europe, Asia, and a small portion of Africa. In general, gray wolvesâ size and weight increase the further north they reside. Gray wolves are social animals, living and hunting in packs of 2-12. A typical pack is composed of an alpha male and an alpha female (the pack leaders), their pups, and several subordinate or juvenile wolves.
