Question

why do birds fly in V formation?​

Answer 1

There are two reasons birds might fly in a V formation: It may make flight easier, or they’re simply following the leader. Squadrons of planes can save fuel by flying in a V formation, and many scientists suspect that migrating birds do the same. Models that treated flapping birds like fixed-wing airplanes estimate that they save energy by drafting off each other, but currents created by airplanes are far more stable than the oscillating eddies coming off of a bird. “Air gets pretty darn wiggy behind a flapping wing,” says James Usherwood, a locomotor biomechanist at the Royal Veterinary College at the University of London in Hatfield, where the research took place.

Answer 2

Answer:

First, it conserves their energy. Each bird flies slightly above the bird in front of them, resulting in a reduction of wind resistance. The birds take turns being in the front, falling back when they get tired. ... The second benefit to the V formation is that it is easy to keep track of every bird in the group.
