Ermine in Winter Coat - Stoat Species Guide & Facts #3365470 (License: Personal Use)

This illustration depicts an ermine (Mustela erminea) in its winter coat, when its fur turns pure white for snow camouflage, except for the black tip on its tail-a key field mark. The animal’s slender body, short legs, and sharp facial features reflect its agility as a predator of small mammals and birds. Its posture suggests vigilance, typical of this highly active mustelid in cold-season environments.
