Life of Birds - To Fly or Not to Fly?

A natural history of bird life narrated by David Attenborough. In this programme, computer graphics recreate the period 150 million years ago when small, fast-running dinosaurs evolved feathers and took to the air. In New Zealand, David examines the environment required by birds which have survived without recourse to flight, and enjoys a midnight encounter with a kiwi, captured on a starlight-sensitive camera.
