Query: Delve into the secret lives...

This 5-part series is a nature documentary for the whole family. Natural violence, in the form of predator vs. prey, is minimized. Although limited to one geographic area, unlike Planet Earth and Life, it still shows the fascinating lives of our feathered friends. The best element to this series is how it busts the myths about being "free as a bird" or "eating like a bird".
