The Geese in the V

Written by Studio AM.

In northern autumn, many migrating geese travel south in flocks. Look up, and you may see them in a clear V shape, one long arm on each side. This shape is not for show. Flying in a suitable formation can reduce the energy some birds use.

As each goose flaps, its wings push the air and leave a small rising current behind. The goose just behind and to the side rides on that current, so it does not have to work as hard. Only the lead goose, at the point of the V, gets no such help.

Experienced birds can take turns leading the flock. A bird moving back from the front may benefit from another bird’s rising air current. In this way, no single bird carries the whole load, and the flock can fly many hundreds of miles together.
