Did you know?
In cold winters, Stoats turn pure white — called 'ermine' — with only the black tail tip remaining, as a form of camouflage in snow
More for experts
Stoats perform a hypnotic 'war dance' — leaping, twisting and somersaulting near prey — which seems to mesmerise rabbits and birds long enough for the stoat to close the distance and attack
Often confused with
Weasel (shorter, no black tail tip, does not turn white), Polecat (larger, dark with pale face mask)
