アカギツネ
Predators of the European mink include the European polecat, the American mink, the golden eagle, large owls and the red fox. Red fox numbers have increased greatly in areas where the wolf and Eurasian lynx have been extirpated, as well as areas where modern forestry is practised. As red foxes are known to prey on mustelids, excessive fox predation on the European mink is a possible factor, though it is improbable to have been a factor in Finland, where fox numbers were low during the early 20th century.
