Life-long birder Christian Cooper takes us into the wild, wonderful and unpredictable world of birds. Whether braving stormy seas in Alaska for puffins, trekking into rainforests in Puerto Rico for parrots, or scaling a bridge in Manhattan for a peregrine falcon, he does whatever it takes to learn about these extraordinary feathered creatures and show us the remarkable world in the sky above.
