They make nests out of grasses, feathers, and muskox wool. They make many snow tunnels. The underground burrows have rest areas, bathrooms, and nesting rooms. FOOD Lemmings eat plants, roots, berries, and lichens. They gather seeds to eat in the wintertime.
Arctic foxes can sniff out lemmings in their burrows under the snow.
They chase the lemmings into their burrows and kill them by biting their necks. The high number of lemmings helps to provide food for many animals. When there are too many lemmings in one area, they migrate to other places. Many drown by running into rivers and lakes. The number of young that a Snowy Owl has depends on whether there are alot of lemmings or not.
