Two reasons. First, it conserves their energy. Each bird flies slightly above the bird in front of him, resulting in a reduction of wind resistance. The birds take turns being in the front, falling back when they get tired. In this way, the geese can fly for a long time before they must stop for rest. The second benefit to the V formation is that it is easy to keep track of every bird in the group. Fighter pilots often use this formation for the same reason.

to decrease the effects of drag on the flock allowing the ones in the back to rest up more so that they may eventually make their way to the front

Leadership, hahaha.
