How do geese fly in a perfect V-formation?

Question

How do geese fly in such a perfect V-formation? They look like the red arrows. How come there aren’t any stragglers?

Name: Ian, Putney
Qualification: My wife works for a company called Goose and I asked questions at the Christmas Party.
Answer: They naturally go into a V-formation for efficiency to reduce drag, so get less tired. Ideally, they would fly one behind each other, but then they wouldn’t be able to see, so they fly in this formation. It happens naturally, because they can sense where the slipstream is. Also, the lead goose drops to the back when it gets tired, in order to get it’s energy back.
