There is only 1 species of mink found in the UK - The American Mink.
As you can probably guess, the American Mink is an introduced species and is wreaking havoc across this ‘newly discovered’ landscape and is now a ‘pest species’ - which can be (humanely) trapped and killed.
But how can one species of mink be so destructive when their are other species of mink across Europe?
American Mink:
As their name suggests - these mink have not evolved to live in a European ecology. They were brought to the UK for their furs and have since escaped or been ’set free’ into un unsuitable environment and in large numbers.
Mink are semi-aquatic mammals and love to eat anything they can fit in their mouths including our much loved and very endangered water voles! They are very territorial and will not tolerate other minks coming too close - often fighting to the death…..
They will also take birds and eggs and are not liked amongst farmers, wildlife enthusiasts or conservationists to name a few parties. Although they are a wonderful sight in themselves when seen wild - they are persecuted wherever they go.
They are black in appearance although can be more brown in cases due to inbreeding when farmed - however their tail is always very bushy and can be almost as long as their body - and they have huge whiskers on their face!
Their bodies are much longer than the average cat, but they have very short legs. As a result, they move about by ‘hopping’ rather than walking like a cat, with their back slightly raised. They will also be seen in or near water - which is also very unlike a cat.
Not An Otter!
Some people get them confused with otters - which can be disastrous - as otters are very rare in most parts of the UK and shouldn’t be disturbed or trapped - and certainly not killed! In the UK they are also a protected species and even getting too close for a picture can be stepping over the ‘legal’ line!
The easiest way to tell them apart if you can only see one animal on it’s own is that the otter has tiny ears for it’s head!
Other differences include the following but aren’t always so easy to spot with one individual passing by in a flash (however if you see a long mammal in the water or on the ground in daylight infront of you for a long time - it will most likely be a mink as otters are very shy and mainly nocturnal).
Eurasian Otter: (Lutra lutra)
Brown, mainly water-based mammal - nocturnal and very wary of humans and dogs.
Rounded, wide face with tiny ears compared to the size of it’s head!
Pale, creamy colour band from the ears, down the throat and to the front legs.
Around 1 meter long (medium dog sized) - with thick, heavy-looking tapering tail.
American Mink: (Neovison vison)
Black, land and water-based mammal - active any time of day or night and not shy!
More pointy face with larger ears - more like a polecat.
Generally the same colour all over - but commonly with a bright white chin.
Up to 50cm long (large cat sized) - with a long, full, fluffy-looking light tail.
All Change:
Luckily for UK wildlife, mink occupy the same habitat as otters but otters are so much larger that the mink move away. Eventually as the otters recover their numbers in the UK, mink numbers will drop to a manageable low - and they will stop eating all our precious wildlife!
However, the European Mink (Mustela lutreola) isn’t so lucky and are listed a endangered! As the American Mink are bigger than them - they are the ones wiping out whole populations in Europe! Unless trapping and habitat loss are dealt with on the continent, European Mink could be seeing their last few strongholds lost to the Americans!
Unfortunately - introduced species rarely ever settle in naturally to a new environment and will always be classed as pest if their habits badly affect other species. So the people who ’saved’ a few farmed mink from becoming coats - could possibly have doomed several other species to extinction!
So, ’save’ one common and hugely widespread domesticated individual from instant painless death - but allow it to painfully kill at least 2 other already restricted and endangered mammal species as well as numerous threatened birds and their eggs.
Not such a well thought out ‘animal rescue’ after all!
