Why do geese fly in 'V?'

Published in Daily Trivia
Migrating geese fly in a V-formation to save energy. A goose's wings churn the air and leave an air current behind. In the flying wedge, each bird is in position to get a lift from the current left by the bird ahead. It is easier going for all, except the leader. During a migration, geese are apt to take turns in the lead position.
