Why Do Birds Fly in a V-Formation? | RapidSmartFacts

When large birds migrate, they often fly in a perfect V-formation.

But this shape isn’t random — it’s aerodynamic teamwork. Each bird’s wings create spinning air

currents called vortices. These vortices generate an upward push of air at the wingtip edges.

Birds behind position themselves to ride this upward push. This lets them use less energy

to stay airborne. Research shows birds in formation can save up to 20–30% of their

energy. They also beat their wings in coordinated timing to maximize the benefit.

The lead bird gets no help — it works the hardest. That’s why birds

take turns leading, rotating positions during long flights. The V-shape also helps birds keep
