There and Back Again

Here's a simple question: When an animal disappears in the winter, where does it go? Oddly enough, this question completely stumped European scientists for thousands of years. And even today, the more we learn about the comings and goings of the animals, the deeper the mystery seems to get. We visit a Bavarian farm with an 11 year old, follow warblers and wildebeests around the world, and get a totally new kind of view of the pulsing flow of animals across the globe.
