Formation Flyers is a term used to describe a group of birds, usually GEESE, flying in a V-shaped formation. This type of flight is used by many species of birds, including GEESE, ducks, and cranes, as a way to conserve energy while migrating long distances. The leader of the formation is usually the strongest and most experienced bird, and the other birds follow in a line behind it. This type of flight has been studied extensively by scientists, who have found that the birds can fly up to 70% farther than they would if they were flying alone.
