Polecat Weasel

The Polecat (Mustela putorius) is a member of the weasel family (Mustelids) and is also known as a 'Fitch' relating to its fur. It is related to stoats, otters, weasels and minks.

Polecats were once widespread and common throughout mainland Britain.

However, due to heavy persecution by gamekeepers up until the late 1930's, polecats where in decline everywhere except for a small population in North Wales. Recovery of populations has resulted in them now being widespread throughout rural Wales, the Border counties and are spreading across the Midlands, South and into the South-East.

The polecat pre-breeding season population is estimated to be 63,000 and increasing.

Polecat Description

Polecat

Polecats are about the same size as a ferret. Male polecats measure 55 centimetres in length with a tail length of 20 centimetres. Female polecats measure 50 centimetres in length and have a tail length of 16 centimetres. Both male and female polecats are similar in appearance.

Polecats have long fur which is almost black in colour and which has a purple sheen exposing a buff undercoat of fur. They have white bandit-like mask markings on their face and ears. Polecats have long tails and short legs. Polecats are somewhat larger than weasels, weighing between 0.7 kilograms for females to 1.7 kilograms for males, however, they are smaller than otters.

Polecat Habitats

The polecats favoured habitats are woodland, riverbank, farmland buildings and surrounding farmland. They favour lowland country below 500 metres. Polecats often make dens in stream banks or under tree roots. They require a home range of about a square kilometre.

Polecat Diet

Almost entirely carnivorous, Polecats will hunt by night or by day for frogs, water voles, eels, trout, rabbits, snakes, ground nesting birds and insects using a keen sense of smell to locate their prey.

Polecat Behaviour

Polecats are solitary in nature, nocturnal and active throughout the year. They emit a pungent musky odour from scent glands located at the base of their tails to mark their territory and particularly when threatened. The polecat is the ancestor of the domestic ferret and can interbreed with them.

Polecat Reproduction

Polecats are mainly polygynous, which means having more than one mating partner. Polecats breed once a year, around May or June, producing litters of 5 - 8 kits after a gestation period of 40 - 42 days. Kits are born with white, silky fur and huddle together in cold weather while in hot weather they lay spread apart. The kits are weaned after 4 weeks and fully grown in around 3 months. The average life span of a polecat is 5 years.

Polecat Conservation Status

Polecats were once almost extinct in Britain. They are considered to be a pest of game and poultry and have been wrongly persecuted for this. They were formerly killed for their fur. Despite diminishing populations, they are not considered to be endangered.
