| Fossils suggest that during the Pleistocene, about 800,000 to 50,000 years ago, the Ungava Collared Lemming lived throughout much of the Arctic regions of North America and Asia. Now it occurs only in the northern half of the Ungava Peninsula in northern Quebec and Labrador, and on two islands in Hudson Bay. An animal with a stocky build, short limbs and tail, small eyes, and external ears hidden in thick fur, this Lemming is found only in tundra habitats, including rocky hillsides and meadows above the timberline. It changes coat color from brownish-gray to white in fall and develops forked digging claws. A variety of predators, including owls, hawks, foxes, and even wolves eat them. In the winter, the Lemmings dig tunnels in the snow. Foxes are said to listen for their digging sounds to capture them.
