Why do migrating birds form V shape

I was curious the other day about the way a flock of flying birds looks like. It looks like a V shape. I thought may be it is because there is just one leading bird and it is easier for other birds to follow a leader? But why the V shape? Why not some other shape? Well, I asked around and it sounds the reason is not that simple. The V shape actually helps birds to fly over the long distance. And also, how do birds choose the leader? That is amazing.
