why do geese fly in a v formation

Nature

Geese fly in a V formation primarily to conserve energy and to maintain effective communication and coordination within the group. Each bird flies slightly above the bird in front of it, reducing wind resistance and allowing the flock to cover long distances more efficiently. They take turns leading the formation, sharing the hardest position to conserve their energy evenly. Additionally, the V shape helps the geese keep track of each other visually, maintaining group cohesion during flight.
