What formatian do geese fly in?

Geese fly in a V formation to reduce air resistance and save energy. When flying in a V formation, the geese create a slipstream of air that helps to lift the geese behind them. This allows the geese to fly more efficiently and cover longer distances without tiring. The geese at the front of the V formation take turns breaking through the air resistance, which allows the geese behind them to glide more easily. This cooperative flying technique allows geese to travel long distances and migrate to warmer climates during the winter months.
