Why Birds Fly in V Shape: Aerodynamics and Efficiency

Birds fly in a V-shape formation during long journeys to save energy.

The bird in front works the hardest, while the others use the air currents it creates.

This is like catching a free ride!

Scientists studied ibises and found they fly in very specific positions to get the most lift from the air.

Birds take turns leading, so no single bird always has to work the hardest.

The birds at the back of the V flap their wings less often and have slower heart rates than the lead bird.
