The Northern Collared Lemming (Dicrostonyx groenlandicus) is a species of rodent from the Arctic tundra of North America and Wrangel Island. It is herbivorous and spends most of its life underground. However, collared lemmings will migrate if their population becomes too dense. They are a favorite prey of the snowy owl and Arctic wolf.
