Is the tundra only a cold, dark, empty, frozen plain? Find out for yourself! See plovers and other birds fly in from thousands of miles away during the brief, warm summer. Watch arctic foxes hunt them, while mosquitoes buzz all the warm-blooded animals. During the long, cold winter, the scene changes. Some animals migrate south again, but snowy owls stay to hunt lemmings, musk oxen forage, and arctic ground squirrels hibernate. Season follows season, and the days grow longer and shorter. The tundra warms and cools, and many animals come and go. Discover the natural variety and life of the tundra.
