In a heartbeat, an ermine (Mustela erminea) will dart at oblivious prey, such as the vole, and dispatch it with a swift bite to the neck. If the vole were in its hole, the ermine would slink right in. These small carnivores can amass dozens of kills for eating later and prefer to hunt mammals though they will also eat fish, eggs, birds, frogs, and insects. Ermines operate not out of bloodlust, but hunger. Their long, lean, active bodies burn so many calories that they must stay fueled to survive. Spot the hunter and its prey in the Ermine and Vole diorama in the Museum’s Hall of North American Mammals.
