About

The American mink is species that is closely related to the weasel and the stoat, however, it is not native to the UK and was originally brought over for the fur trade. After some individuals escaped or were released across mainland UK and Ireland. The American mink is a semi-aquatic species that can dive underwater up to 6 metres in depth. The American mink is nocturnal and are generally solitary apart from between February and April when breeding takes place. The young are born between April and June and Minks will have up to 10 young and start hunting after 8 weeks.
Due to their introduced status and the effect that they have on local species by reducing the number of breeding birds and water voles, the species has been controlled to reduce their impact.
