The movie about the girl with the geese was called "Fly away home", with Anna Paquin and Jeff Daniels. A real tear jerker.
I saw Winged Migration, the best movie I saw last year. I hope it gets the Documentary Oscar. It includes scenes of geese landing on a French war ship to rest. One goose getting caught in an oil slick in Holland and getting left behind when the flock takes off without it. Geese migrating through the Himalayas. Breeds of waterfowl I never knew existed. I highly recommend this film.
