Why do birds fly in shape of chevron?

Answer 1

Birds fly in circles for various reasons.

• The birds are simply gliding on thermals, which move in circles.
• The birds are searching for prey
• The birds are performing a mating ritual by flying with each other.

Answer 2

Birds that fly in a V formation carefully position themselves, and time their wing flapping, so they can draft off the bird in front of them. This helps them conserve energy, sometimes by as much as 70%. During flight, the birds at the tips and in the front of the V swap positions at regular intervals to cut down on fatigue.

Answer 3

The bird at the front of the chevron is usually the strongest flier of the group. The birds flying behind it then have an easier time flying by riding the lead bird's wake.
