American mink
The American mink may pose a threat to poultry. According to Clinton Hart Merriam and Ernest Thompson Seton, although the American mink is a potential poultry thief, it is overall less damaging than the stoat. Unlike the stoat, which often engages in surplus killing, the mink usually limits itself to killing and eating one fowl during each attack. Studies in Britain indicate poultry and game birds only constitute 1% of the animals' overall diets; small mammals, especially rabbits, tend to dominate, followed by fish and birds, especially moorhens and coots.
