The American mink was introduced to the UK for fur farming in the 1920’s. Since that time a number of escapes and deliberate releases have allowed it to establish in the wild. Mink are semi-aquatic mustelids  usually with dark brown fur and a white patch on the chin. It is a generalist predator that takes both terrestrial and aquatic prey.
