European polecat European polecat The European polecat ("Mustela putorius") – also known as the common ferret, black or forest polecat, or fitch (as well as some other names) – is a species of mustelid native to western Eurasia and north Morocco. It is of a generally dark brown colour, with a pale underbelly and a dark mask across the face. Occasionally, colour mutations, including albinos and erythrists, occur. Compared to minks and other weasels – fellow members of the genus "Mustela" – the polecat has a shorter, more compact body; a more powerfully built skull and dentition; is less agile; and it
Polecat–mink hybrid Polecat–mink hybrid A polecat–mink hybrid, also known as "khor'-tumak" by furriers and "khonorik" by fanciers, is a hybrid between a European polecat ("Mustela putorius") and a European mink ("M. lutreola"). Such hybridisation is very rare in the wild, and typically only occurs where European mink are declining. The two species likely began hybridising during the early 20th century, when Northern Europe underwent a warm climatic period which coincided with an expansion of the range of the polecat into the mink's habitat. Polecat–mink hybrids have a poorly defined facial mask, have yellow fur on the ears, grey-yellow underfur and long, dark-brown
