Why do birds fly in a v?
Most commonly see are ducks flying in a V shaped formation when they migrate south for the winter. The reason they fly in such a shape, is so that one can take the lead, and when it gets tired, it can fall back and another will take it’s place. Also, the formation helps the other birds save energy by flying off the “disturbed” air that the lead bird is creating, and they can ride off of it and not get worn out so much. When a bird flies, the air above and below its wing get “shifted” out of place, and it creates an upward current. By riding off that current, a bird behind it can save energy. It’s also why you’ll see cyclists riding behind each other and race car drivers (NASCAR) do the same. The V shape comes from birds riding off each others current, since the outside wing will stick out more than it’s body, birds will place themselves right behind the outside wing.
