"Wolves Airdropped Into US To Tackle Moose Problem"

"With the wolf population dwindling in a Michigan park, four were trapped in Ontario and transported by helicopter"

"At a remote national park, four Canadians were recently airdropped into a dizzying new life in America.

They are expert moose hunters, accustomed to cold climates, and covered in fur.

A quartet of Canadian wolves was transported by helicopter from their home in Ontario to Isle Royale national park, covering an 894 sq mile island in the US Great Lakes, to deal with the burgeoning moose population. Scientists also hope to bolster a dwindling population of wolves that already exists on the island."
