Geese fly in a V formation to increase flying range. By flapping its wings, each goose creates uplift for the goose behind it, allowing the flock to travel 71% further than if each flew alone. Any goose that falls out of formation feels increased drag from flying solo, encouraging it to quickly rejoin the V. Geese also take turns leading the formation, rotating the point position when tired, and work as a team to share leadership and help each other reach their destination quicker and with less effort than if they were alone.
