America's Wild Seasons: Winter
It's winter in America, when darkness falls faster, food grows scarcer, and wildlife is pushed to the limits. Some animals will tough it out during these brutal months while others will turn it into an advantage. Still others will escape to the warmth of the south...where survival is still far from guaranteed. Join us as we explore wild America during the most demanding season of the year, from tiny monarch butterflies to mammoth humpback whales, and from colorless landscapes buried in snow and ice to the vibrant beauty of the aurora borealis.
