Lessons we get from wild geese

Why do geese fly in a V-shaped form? As each bird flaps
its wings, the wind it makes lifts the bird that follows behind.
The geese gather lift from one another. This helps the geese
travel faster. The geese behind the leader make honking
noises. The noise encourages the lead birds as they fly along.
The honking makes the birds keep up the speed. By honking,
the birds tell each other, “Good job.” If a goose gets injured
or sick, it falls out of the V. Two other geese from the group
follow it down to the ground. They help or protect the bird.
What can we learn from geese? We should take good care of wild animals.
