A rocket-like appearance... White in winter with a brown back or a beige belly in summer, with a black tail tip all year round... Can you guess who's playing hide and seek in the scree?
It's the Stoat, a small, fast and powerful mustelid, a member of the Badger and Marten family. It doesn't actually play, but rather hunts voles, its favourite prey, thanks to its elongated shape, which allows it to slip into their burrows, where they think they're well protected...
