Why do Birds fly in V Shape? | #aumsum

Flocks of birds like geese, pelicans fly in V formations to make flight easier. In V formations, when a bird flaps its wings, the air behind the bird gets pushed downward creating a downwash, while the air towards its sides gets pushed upward, creating an upwash. This produces rotating vortices. If another bird flies in these upwash zones, it gets a free lift and glides due to reduced air resistance. Thus, birds are able to fly long distances without putting much effort and maintaining a
