Why ducks fly in v formation

It took time for them to learn to fly in a V… and that adds one final surprise to the mix. They learned [V-formation flying] from each other. Upwash exploitation and downwash avoidance by flap phasing in ibis formation flight. All rights reserved. Why do some birds fly in a V? Here is the standard explanation for the V-formation: As a bird flaps, a rotating vortex of air rolls off each of its wingtips. Share Tweet Email. Go Further.

Another bird can spend less energy by flying in this sweet spot, which is slightly behind and above the first bird. The concept is similar to cyclists riding behind one another in a bike race to save energy.

For geese, spending less energy means flying longer distances. When the lead bird gets tired, it drops back in formation and another bird moves to the front. Flying in the V formation also lets the birds keep in visual contact with one another so they're oriented in the right direction. That way, they don't crash into each other or get lost along the way. Geese flying in a V formation makes a lot more sense to me. I have been told why they fly in that formation before but this article makes it a lot more clear for me.

Geese can fly longer when expanding less energy because it gets them more strength and energy. I think this is amazing to know this because this is why birds fly in a V-shape. Flying that way can reduce the energy used in long migratory flights.
