- As each goose flaps its wings it creates “uplift”, an aerodynamics orientation that reduces air friction, for the birds that follow. By flying in a V-formation, the
whole flock achieves a 70% greater flying range than if each bird flew alone.
- When a goose falls out of formation it suddenly feels the friction of flying alone. It will quickly adjust and move back into formation to take advantage of the lifting power of the bird immediately in front of it.
- Empowering others to lead: When the lead goose in the front gets tired, it rotates back into the formation and allows another goose to take the leadership position.
- The geese at the rear honk to recognize each other and encourage those up front to keep up their speed.
- When a goose gets sick or wounded, two geese drop out of formation and follow it down to help and protect it. They stay with it until it dies or is able to fly again. Then, they launch out with another formation or catch up with the flock.
- The geese migration routes never vary. They use the same route year after year even when the flock members change. The young learn the route from their parents. In the spring they will go back to the spot where they were born.
- When flying over mountain ranges the birds will fly closer to the ground to take advantage of the air movement over the mountains. As air hits a mountain range it creates an updraft which aids the birds. On the way down the other side it gives the birds a bit of a rest as they coast downhill with the current.
