A film requiring concentration, patience, and a love of birds.Let's forget The Bear and Jonathan Livingstone Seagull: this is how many people love to see nature documented. A visually striking piece, so understated that you may well take comfort when you realise that you will not hear any over-dubbed human voice - an unnecessary feature of Winged Migration.The final images of the film, showing birds in the wake of an oil spill, are enough to make us all feel guilty that humans have evolved as the dominant species on Earth.Mother Nature, soon you will make us sorry !
