Dicrostonyx richardsoni (Richardson's collared lemming)

Wikipedia Abstract

The Richardson's collared lemming (Dicrostonyx richardsoni) is a small North American lemming. At one time, they were considered to be a subspecies of the Arctic lemming, Dicrostonyx torquatus. Some sources believe they are a subspecies of the northern collared lemming, Dicrostonyx groenlandicus. These animals are found in the tundra west of Hudson Bay in north-central Canada. They feed on grasses, sedges and other green vegetation in summer and twigs of willow, aspen and birches in winter. Predators include snowy owls, mustelids, and Arctic foxes.
