Stoats are very similar to weasels in appearance, although are usually larger and have a prominent black tip at the end of their tail. They grow up to 30cm long and have sandy brown fur on top and white fur underneath during summer, but are completely white during winter, apart from the tip of the tail.

Stoats are surprisingly multi-talented: they can run, swim, climb trees and even (some say) dance. Stoats have been recorded ‘transfixing’ rabbits by doing a sort of dance. The hypnotised rabbit fails to notice the stoat come within striking distance – and consequently is easy prey for the stoat.

Long and thin with very long tails, stoats are one of the few species able to follow burrowing mammals into their homes. They are also skillful tree climbers and strong swimmers. Add to the mix that stoats are capable of killing animals much larger than themselves, and you have a fearsome predator on your hands.

Stoats are largely nocturnal, but can sometimes be spotted during daylight hours. They make their dens in hollow trees, burrows or dry stone walls. Look out for them along waterways flowing near moorland, woods and mountains.

In winter, it is not unusual for the stoat’s fur to turn completely white. At this time they are called ‘ermine’.
