I was quite pleased with this movie until I watched the "behind the scenes" featurette on the DVD. It turns out that most of the extraordinary close-ups of winged flight that make the movie memorable are NOT of wild migrating birds. Rather, the filmakers raised and domesticated all sorts of birds through a process known as "imprinting" so they would be comfortable flying next to the noisy photography planes. Then they took their birds all over the world to dramatic backdrops like the Sahara and Monument Vally. They also used these domesticated birds for the dramatic set pieces revolving around birds trapped in sludge, stuck in a blizzard, escaping cages, or wandering the desert. Not only are these set pieces heavy-handed and overly dramatic, but the fact that the birds are not even wild and were placed in these situations really undermines the credibility of the film.
7 out of 10 (minus 1 point for the use of domesticated birds and minus 2 for putting ridiculously staged drama scenes in an otherwise beautiful nature film)
