All geese like to fly in the V formation also known as a skein formation. This formation helps with their flying efficiency and how far they can fly.
This is called the V formation which greatly boosts the efficiency and range of birds. This reduces the amount of drag that the birds produce.
all birds that fly in a V formation fly in the upwash from the wings of the bird ahead, which assists each bird in supporting its own weight. Drag is considerably decreased and thus rage of flight increased. Birds rotate to and from the front at time to time
It is fairly random which side new birds join.
