There are several key reasons why many bird species fly in a V formation: - Energy efficiency - By flying in a V, birds can fly farther using less energy. Each bird flies in the updraft from the birds next to it, allowing them to glide more. This gives the flock an overall energy savings of up to 70% compared to a single bird flying alone. - Aeronodynamics - Wingtip vortices are generated by each flapping wing, and the air disturbance patterns interact in a way that is helpful rather than disruptive to the bird immediately behind. It provides stabilizing lift enhancement. - Improved visibility - With birds spaced evenly behind and to the sides of one another, more eyes are available to watch for predators. Any evasive maneuvers can be seen more quickly by the whole flock. - Navigation - Flying V formations help coordinate directional changes and migratory paths across long distances. Leaders can take turns at the front to share navigation duties. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . #birds #fly #vformation #formation #why #animals #science #migration #aerodynamics #nature
