Another alien invader

It is a beautiful animal but it shouldn't be here.  This is the American mink (Neovison vison), an invasive non-native species. The UK population originated from escapes and deliberate releases from fur farms by pea-brained so-called "animal rights activists".  The number of mink may be declining as the otter population increases but mink are widespread in this country and are responsible for the destruction of much of our native fauna and the extinction of water voles in large parts of the countryside.

Although the original farmed animals were of all sorts of colours most have reverted to the wild type dark brown like this one.
