Birds and flight- more insights, even more questions

BBC News - Fly like a bird: The V formation finally explained: "Scientists from the Royal Veterinary College fitted data loggers to a flock of rare birds that were being trained to migrate by following a microlight.

This revealed that the birds flew in the optimal position - gaining lift from the bird in front by remaining close to its wingtip.

The study, published in the journal Nature, also showed that the birds timed their wing beats.

A previous experiment in pelicans was the first real clue to the energy-saving purpose of V formations. It revealed that birds' heart rates went down when they were flying together in V."
