The Sense of Geese: Next time you see geese heading south for the winter, flying along in the V formation, you might be interested in knowing what science has discovered about why they fly that way. It has been learned that as each bird flaps its wings, it creates an uplift for the bird immediately following. By flying in a V formation, the whole flock adds at least 71 percent greater flying range, than if each bird flew on its own. When the lead goose gets tired, it rotates back in the wind and another goose flies’ point. The geese honk from behind to encourage those ahead to keep up their speed. When a goose gets sick or hurt and falls out of formation, two geese fall out of formation and follow it down to help and protect it. They stay with the goose until it is able to fly again. Then they all fly together to catch up with their flock. Geese work together and do their best never to leave each other behind. This true story tells the adventures of four little goslings that became separated from their family. You’ll never guess what happened next!
