Wolves inevitably prefer wild game to livestock.
In North America, bison, deer, elk, moose, and beaver head the wolf's menu. This underlines the importance of reintroducing natural prey in areas where wolves are being restored. In accounts from the last two centuries, wolves were often begrudgingly admired by their human executioners. Many stories portray them avoiding traps, refusing bait, and dodging bullets. Wolves can make themselves vomit at the first sign of nausea or irritation.
