Our smallest carnivore, the Weasel looks like a mini version of the Stoat.

Weasels are very active hunters, feeding on small mammals such as voles and mice, as well as small birds. They are found in a variety of habitats: woodland, grassland, hedgerows, heath-land and moorland. Weasels mate in spring and summer, having two litters of three to six kits a year.

How to Identify

The Weasel has an orange-brown back with a white throat and belly. Smaller than a Stoat, with a relatively shorter tail with no black tip.

Where to Find

Found throughout England, Wales and Scotland, but absent from Northern Ireland and most islands.

How People can Help

Weasels are not considered to be rare in the UK, but the habitats that they favour are declining – our grasslands, heathlands and woodlands are all under threat. Encouraging farmers, landowners and gardeners alike to have a wildlife-friendly approach, The Wildlife Trusts are working towards a Living Landscape: a network of habitats and wildlife corridors across town and country, which are good for both wildlife and people. You can support this greener future by joining your local Wildlife Trust.

Did You Know?

Weasels are so agile that they can climb trees to steal and eat young birds and eggs. They can also fit into the burrows of their small rodent prey.
