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 clear line of sight.

Besides this, since the bird in the lead faces greater air resistance, the birds keep changing their positions in the V and take turns as leaders. This maximizes the use of each bird's energy, allowing flocks to fly without having to stop.
