Of Birds and "V"

When you see birds flying along in "V" formation, think about what science has learned about why they fly that way.

As each bird flaps its wings, it creates uplift for the bird immediately following it. By flying in a "V" formation, the whole flock can fly at least 71% farther than if each bird flew on its own.

When a bird falls out of formation, it feels the resistance of trying to do it alone, and quickly gets back into formation to take advantage of flying with the flock.

When the lead bird gets tired, it rotates back in the wing and another bird flies on the point.

The birds chirp from behind to encourage those up front to keep up their speed.

Finally, (get this!) When a bird weakens or is wounded and falls out of formation, two birds fall out and follow down to help and protect the bird. They stay with the bird until it is either able to fly or until it is dead, and they then set out on their own or with another formation until they catch up with the group.
