2. Mink, lateral view
3. Ferret & Mink compared
4. Details of specimens   illustrated
It is possible to separate Mink from wild Polecat skulls, but the situation iscomplicated by the presence of feral Ferrets which are variable and tend to overlap with both Polecats and Mink in some features. The examples illustrated here show that the Ferret skull is more robust in appearance, with a bigger occipital crest.
