Diet [ edit] In North America, where the ecological niche for rat- and rabbit-sized prey is taken by the larger long-tailed weasel ( Neogale frenata ), the American ermine preys on mice, voles, shrews, young cottontails, [6] chipmunks, deer mice, jumping mice, and house mice. Usually the ermine kills by biting at base of skull.
