Ducks fly together for a few reasons. One of the main reasons is to conserve energy. By flying in a formation, known as a “V” formation, ducks can reduce air resistance and take turns leading the flock. This helps to reduce the amount of energy needed to fly, allowing the ducks to cover longer distances more efficiently.

Another reason ducks fly together is for communication and navigation. Flying in a formation allows ducks to communicate with each other through vocalizations and body language. This helps them to stay together as a flock and avoid obstacles or dangers along the way.

Lastly, flying in a formation also provides some protection from predators. By flying in a group, ducks can increase their chances of detecting predators and defending themselves against them. Additionally, flying in a group makes it harder for predators to target an individual duck.

Overall, flying together in a formation helps ducks to conserve energy, navigate, communicate, and protect themselves while migrating or traveling together.
