The V-formation provides an optimal use of the Bernoulli Effect.

Explanation:

The lead bird (the strongest flyer) provides a low pressure area in its wake; in effect, this "vaccuums" birds behind it along with less effort on their part. By flying in a V-formation, two birds are able to take advantage of the low pressure area provided by the lead bird.
