Badgers are our most common mustelid, with an estimated population of more than half a million. Our final mustelid is the pine marten.
Key identification features include:. Pine martens had disappeared from most of the UK by the 20th century due to hunting and destruction of their woodland habitat. As a result, the majority of the population is now found only in Scotland.
Only a handful of isolated populations are left in both countries. We are working to help pine martens return to the woods of England and Wales. Once persecuted to extinction, find out how we're helping pine martens make a welcome return to the UK's woods. Primordial landscapes, tangled branches, breathtaking wildlife and miles of woodland trails.
From the countryside to cities, we care for thousands of woods throughout the UK, all free to visit. Stoat or weasel? How to tell the difference. Have you been lucky enough to encounter a stoat or weasel on a woodland walk? The trick is in the tail The easiest and most reliable way to tell a stoat Mustela erminea from a weasel Mustela nivalis is the tail.
Movement - Stoats have a characteristic bounding gait with an arched back. The movement of weasels is often quicker and flatter to the ground. Colour - Stoats sometimes turn white in winter, especially in Scotland. UK weasels stay brown all year round. Where to see stoats and weasels Stoats and weasels are found throughout mainland Britain. The rest of the mustelid family Closely related, stoats and weasels are members of the mustelid family.
This is around twice the length of a mink - and an otter can be ten times heavier. Colour: Otters have brown fur, while mink are notably darker, appearing almost black. Polecat Mustela putorius Like the otter, legal protection has helped polecat numbers grow in recent decades. Mustelids can't climb, and cats often can reach the back of their necks with their claws — something dogs don't find as easy. Furthermore, if you do find stoats up for sale, they usually are illegally captured wild specimens, so if you buy one, you'll be promoting illegal and harmful wildlife trade.
The list, which is largely dominated by plants and insects, includes the cute little stoat as one of the top 10 invasive mammals.
What makes them so invasive? Stoats are native to Asia, Europe and North America , but they were introduced to New Zealand and Britain against the advice of many scientists to help control the rabbit population. Remember how they can reportedly immobilize rabbits by mesmerizing them with a "dance"?
However, after just a few years, the bird population rapidly declined, and their introduction also had a devastating effect on rodent species. That's because stoats can adapt to many environments and thrive in most climates. The stoat also is an opportunistic predator, moving rapidly and checking every available burrow or crevice for food, and often climbing trees to find bird nests.
When they finally do give birth, they typically have between five and 15 babies called kits at a time. They also usually only have one litter during their life, which is an average of four to six years.
The males don't help raise the babies. This white-pink fur will change as the stoat gets older. Male and female stoats live separately in their own dens, and stoats are known to have several dens they use at the same time.
Their den sites are well-hidden, typically the nests of prey they've killed and taken over. They include holes in tree trunks and rabbit burrows. Stoats check every burrow and hollow they see, and if they find a ground-nesting bird it has very little chance to escape.
The root word for "stoat" is likely either the Dutch word "stout" meaning naughty or the Gothic word "stautan" meaning to push. It also eats insects , fish, reptiles , amphibians and invertebrates. When food is scarce they will eat carrion dead animal carcasses.
It is a very skilful tree climber and, like a squirrel, can descend a trunk headfirst. The stoat is capable of killing animals much larger than itself. Stoats kill their prey by a bite to the back of the neck and may travel as far as 8 kilometres in one hunt.
Stoats are fierce predators and can move at speeds of 20 miles per hour when hunting. In most areas in which stoats and weasels co-exist, the weasel generally takes smaller prey and the stoat slightly larger prey.
The larger male stoats generally take larger prey than females. The stoat is territorial and intolerant of others in its range, especially others of the same sex. The stoat typically uses several dens, often taken from prey species. It usually travels alone, except when it is mating or is a mother with older offspring. Stoat communication occurs mainly by scent, since the stoat has a sensitive olfactory system relating to sense of smell.
As a result, much of this communication is missed by human observers. However, stoats are believed to identify females in estrus by scent and also the sex, health and age of prey. Some kinds of rodents such as voles have counter-adapted by being able to shut down reproduction which makes females slower and easier to catch if they smell the odour of stoats. The stoats visual resolution is lower than that of humans and colour vision is poor, although night vision is superior.
Tactile information is presented by the vibrissae, or whiskers. When alarmed, a stoat can release a powerful musky smell from its anal glands. Stoats mate in May to June followed by a period of delayed implantation.
