The animals that live on the tundra must prepare for survival in the winter months. Miller describes the adaptations that various species use to survive in the Arctic. The Arctic ground squirrel stores berries and seeds for survival. A frog partially freezes and hibernates until spring. Birds, such as ptarmigan can survive during the day, but must find shelter for night. As spring arrives, the tundra is revitalized as various animals come out of hibernation.
