Why do geese have to wait in line when flying?
In fact, the main purpose of this is to save physical strength, because each migration is a long journey of thousands of kilometers. Although geese can fly about 70 to 90 kilometers per hour. But it still takes a month to two months to fly to the destination. Therefore, in this long journey, the team of Lun is very well organized, often maintain a neat herringbone team, or a one-line team, generally in front of the geese are very powerful and experienced, when the head goose in front of the wings, will make the air flow speed accelerate, produce a weak updraft, the geese in the back can use this updraft to fly fully, but also let the small swallow in the middle of the line fly more labor-saving, will not fall behind, but also improve the overall flight ability.
At the same time, the physical strength of the leading geese will also be consumed quickly, and it is easy to fatigue, so it is necessary to change the formation frequently, and let the strong geese in the team be the first geese. This is like a long-distance running on the sports field, experienced athletes will not take the initiative to run in the front at the beginning, but will run closely behind a person, because the air resistance will be smaller, running will save some effort, and then add more force to the sprint, which is the truth.
