DAY 59: TEAMWORK

Why do birds fly in V formation? Scientists have determined this serves two important purposes: Firstly, it conserves their energy. Each bird flies slightly above the bird in front of it, resulting in a reduction of wind resistance. The birds take turns being in front, falling back when they get tired.  In this way, they can fly for a long time before they have to stop for a rest.  The V formation enables adding at least 70% greater range than if each bird flew on is own. Secondly, they are able to keep track of each bird in the group. The brilliance of teamwork!
