Flying in a V formation allows geese to fly farther and more efficiently by reducing wind resistance. When a goose falls out of formation, it feels increased resistance and quickly returns. Staying united with those going in the same direction reduces individual effort. Leadership is shared, with different geese taking turns at the front. Geese encourage each other with calls to maintain speed. When one goose is sick or injured, others care for it until it recovers or dies. Working together makes life easier and more fulfilling.
