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.
Hunting and habitat destruction have caused a steep decline in populations. Gray wolves are now found only in a few areas of Canada and the United States. Wild wolves live in these states: Alaska, Idaho, Michigan, Minnesota, Montana, Wisconsin and Wyoming.olves often hunt in packs for large prey such as deer, moose, sheep, goats, caribou, elk, bison, and muskox. Wolves also prey on rodents, beavers, fish, and birds. Behavior: Gray wolves are territorial and live in packs lead by the alpha pair.
