Mustela putorius

The European polecat (Mustela putorius), also known as the black polecat and forest polecat, is a mustelid species occurring in Europe and the Rif mountains. It is of a generally dark brown colour, with a pale underbelly and a dark mask across the face. Occasionally, colour mutations including albinos, leucists, isabellinists, xanthochromists, amelanists, and erythrists occur. It has a shorter, more compact body than other Mustela species, a more powerfully built skull and dentition, is less agile, and is well known for having the characteristic ability to secrete a particularly foul-smelling liquid to mark its territory.

It is much less territorial than other mustelids, with animals of the same sex frequently sharing home ranges. Like other mustelids, the European polecat is polygamous, with pregnancy occurring after mating, following induced ovulation. It usually gives birth in early summer to litters consisting of five to ten kits, which become independent at the age of two to three months. The European polecat feeds on small rodents, birds, amphibians and reptiles. It occasionally cripples its prey by piercing its brain with its teeth and stores it, still living, in its burrow for future consumption.
