The answer

They do this for efficiency. When a bird flies, their wings create an updraft right behind the bird--directly behind the wing tip. So another bird can take advantage of this and get a bit more lift to make it easier to fly. That's why birds do not fly directly behind the bird in front but a bit off to the side to get the wing tip updraft effect. This eventually makes a group of birds form a V formation. You can get more details about why birds fly in a V formation on Wikipedia.
