Here is what science has to say about why geese fly in V formation.
I found it to be fascinating and inspiring.
As each bird flaps its wings, it creates an uplift for the bird immediately following.
By flying in V formation the whole flock adds at least 71% greater flying range than if each bird flew on its own.
When a goose falls out of formation, it suddenly feels the drag and resistance of trying to go it alone ... and quickly gets back into formation to take advantage of the lifting power of the bird in front.
When the Head Goose gets tired, it rotates back in the wing and another goose flies point.
Geese honk from behind to encourage those up front to keep up their speed.
Finally...and this is important...when a goose gets sick, or is wounded by gunshots, and falls out of formation, two other geese fall out with that goose and follow it down to lend help and protection. They stay with the fallen goose until it is able to fly, or until it dies; only then do they launch out on their own, or with another formation to catch up with their group.
Wouldn't it be great if we could learn to have the sense of a goose, and stand by each other like that.
