This documentary presents an epic portrait of winter bird migration. Filmed on all seven continents over four years, the footage is brought together into one portrait of a journey that's uniformly arduous for all kinds of different birds. Rather than concentrating on statistics and facts, the film near-wordlessly portrays the sheer physical effort demanded of the birds on their disparate routes. Along the way, we see the many dangers they face, from man-made waste to a group of hungry crabs.
A homeless musician's life is transformed after he discovers a flock of wild South American parrots living in San Francisco. How they got there is a mystery, but Mark Bittner forms a bond with the exotic birds through his music and his patient, attentive care. Over time he comes to appreciate their individual identities and makes a case for humans to reevaluate their relationship to animals. When he is forced to leave them, he despairs over the birds' fate.
