Why birds fly in a V-Formation

Have you ever wondered why birds fly together in a “V” shape pattern? Well, that is mainly because they are able to fly up to 70% further than a solo bird using the same amount of energy. This is what I call teamwork. The full explanation can be found at Aerospaceweb. A snippet is as follows.

By spacing themselves apart properly, birds can achieve optimum positions that reduce the drag of every bird in the formation. However, not all birds benefit equally. Your speculation about the lead bird being in the best position is actually incorrect. This bird has to work the hardest since it flies into undisturbed air. The upwash that this bird creates improves the aerodynamics of the two behind it, and these two further improve conditions for the next two birds in line.
