Yes, like everyone else who has seen (or will see) Winged Migration, I found myself wondering time and again how they shot this film of real birds. Fortunately, with the DVD’s special features, some of the details are available. Just incredible visual scenery, without effects. With all the possibilities for simulation and creation, recording the real world from innovative viewpoints is little short of amazing. Ninety minutes felt like a bit much, but I’m not sure what I could cut… and the filmmakers mentioned flying more than 15,000 hours in the 3-4 years of filming, so it’s not like they didn’t edit already. The website isn’t much, but it does have a map of the actual migration patterns followed.
