Secret of V-formation flight found

Researchers have finally found out just why many birds fly in a V-formation.

A team of scientists fitted tiny little computers to a flock of birds as they migrated south for the winter - and its hoped the results can teach us a thing or two about our own flying habits.

Lead researcher Dr Steven Portugal explained: "They're seemingly very aware of where the other birds are in the flock and they put themselves in the best possible position."
