Geese fly in a V formation to increase flying range and efficiency. Each goose flaps its wings to create uplift for the goose behind it, allowing the flock to travel 71% further than if each flew alone. When a goose falls out of formation, it struggles and quickly rejoins to gain the benefits of flying together. The leadership role is shared, with the lead goose rotating to the back to rest while another takes over. Geese honk from the back to encourage those in front to keep up the pace, and if one goose is injured, two will stay behind with it until it recovers or dies, then catch up to rejoin the flock.
