1. The wild geese form a "V" shape when flying. This labor-saving flight mode improves the flight ability by 71% compared to the lone wild goose flying alone
2. The wild geese flap their wings when flying. When flying in a queue, it provides updrafts for the geese behind, fanning the surrounding air into an upward and forward airflow. With this airflow, each goose can fly with less effort. When the geese leave the team, they cannot use the airflow to help, so they get tired quickly
3. The geese who are separated from the group, without the encouragement of their companions, lose their direction and lose the motivation to move forward, and it is impossible to go alone Arrived in the south
4. Stray geese
A group of geese are flying to a warm place to spend the winter. Their neat ranks are like the word "人" written in the sky.
One day, a young wild goose suddenly left the team and flew away by himself. As it flew, it thought: "Why do I have to line up? How unfree!" It flew, and flew. Gradually, it felt tired and its body became heavier and heavier. Only then did it regret that it should not leave the collective.
At this moment, an older goose flew to pick it up. It asked strangely: "Why can't it fly after leaving the team?"
The older goose The wild goose told it kindly: "Everyone flies in a queue and stirs up the surrounding air to create an upward and forward airflow. With this airflow, each goose saves a little effort when flying. If you leave the team, you can't take advantage of the airflow. Help, so it soon got tired."
The young wild goose understood, and it followed the older wild goose to catch up with the team.
