Do you know why geese fly in V formation?|
Every year, once in spring and in fall geese and cranes fly over our Nature Preserve in Texas. First we hear them, look up and see them flying in a perfect V formation. This V-shaped formation has two important purposes:
A) 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.
B) It is easy to keep track of every bird in the group.
Fighter pilots often use this formation for the same reason.
