We often see geese flying in the sky, so why do geese line up when they fly?

Wild goose. It is a migratory bird and migrates every year, but unlike other birds, geese are generally divided into teams. Whether it is in the text or in real life, almost all the geese we see are lined up with the word "one" or arranged into the word "human".

So why do geese use this way of flying?

Strictly speaking, this way of flying is to save physical strength. The migration of geese themselves is a long process, often requiring a long journey of about two months. Without some methods to conserve energy, it will be difficult for the whole team to fly to the place where they are going to move.

The flying method of the word "one" or "person" can allow the geese to rest halfway.

1. In life, the wild geese we see are all flying in a special way. The most common is the word "person", which has a head bird in front and then a row on each side, like a "person" character. Sometimes you can see them lined up in a row, forming a "one" character.

In this case, the main reason is to save physical strength.

From a flight point of view, geese use rising air currents to glide, and the larger the air current, the less effort it can fly. In addition to the air coming from the air, this air flow also has the wings of the geese themselves. The flapping wings in front create an air current, so the geese behind will fly with less effort.

The word "person" is generally a flying posture, and the word "one" belongs to the braking deceleration posture.

2. In addition to saving physical strength, the way of queuing allows them to better defend against enemies. In the face of external attacks, this posture can also be regarded as a defensive formation. Under normal circumstances, there will be some experienced geese in the team who will take turns to take the lead in the flight.

This kind of wild goose, which we can call the "head goose", can lead the whole team.

In the normal wild goose team, there are usually several "head geese", which take turns to fly first. By changing the formation, let the person be replaced to rest temporarily. It can be seen as a team with a division of labor and cooperation, with several leaders leading the whole team forward.

One of the leaders rested, and the other stepped forward.

3. The geese that are migratory birds during their migration time are generally from south to north and then from north to south. It's a simple way, it's only twice a year, but each time it takes a lot of time. Under normal circumstances, it takes 1-2 months for geese to complete their migration.

The endurance of this long journey is enough to be awe-inspiring.

And the reason why they travel long distances is mainly to reproduce and survive. When the weather is cold, they go to the south to spend the winter, and when the weather gradually warms up, they return to the north to find food. In addition, the geese have a certain grasp of the weather to avoid encountering a situation that is still cold in the north after migration.

These geese have to line up when they fly, these geese are very united and afraid of the enemy, so they will line up, also because their ability is relatively weak.

Because this can reduce the influence of air currents on them, the geese in the back are more labor-saving, so the role of the head goose is very important.

Reducing the consumption of physical strength can allow them to reach their destination very quickly, and most of the geese fly in a herringbone shape during the flight.

A flock of geese fly in a herringbone in the blue sky.

A flock of geese flew in the blue sky for a long time.

A flock of geese. Belch... Can't think of =v=

Ask for adoption and give good reviews =w=

Thank you for your praise

A flock of geese flew neatly in the blue sky.

A flock of geese flies leisurely in the blue sky.

It is because they fly all day long, and the strength of one goose alone is not enough, and they must help each other in order to fly fast and far. When the vigorous geese flutter their wings and fly, the tips of the wings slowly fan a gust of wind, and send them from below to the top, so that the geese will be gently lifted, and the geese will not be left behind after a long journey.

Generally by the front of the wild goose, is very powerful, very experienced, disturbing Qiyin due to the head of the goose flapping the wings, driving the air next to the wild current, if the line into a "human" shape or "one" shape to fly, the back of the wild goose will fly very easily, do not have to rest many times.

During the flight, a low pressure area will be formed behind the head goose, and the wild goose that follows it can use this low pressure area to reduce the drag of the air when flying. Beneficial to the ability to fly continuously for the entire group.

The same principle can be found in athletics, where some experienced athletes do not start in the first place, but run closely behind the other, because the air will have less resistance to him than in the first place. It's also easier to run.

1. Wild geese, also known as wild geese, swans, and large migratory birds, are national second-class protected animals. The wild geese are full of enthusiasm and can encourage their companions with their cries.

2. In long-distance flights, geese will use the rising air currents to glide and save physical strength. The geese in front flap their wings to form a weak updraft, and the geese in the back use the lifting force of the updraft to glide. One follows the other, so that a neat line is formed.

In addition, queuing is also good for defending against predators.

3. The geese maintain a strict and neat formation, that is, they are arranged in the shape of "people" or "one". Because they laugh at Liang Tianfei, the strength of a goose alone is not enough, they must help each other in order to fly fast and shoot far. When the vigorous geese flutter their wings and fly, the tips of the wings fan a gust of wind, and send them from below to the top, so that the geese will be gently lifted, and the geese will not be left behind after a long journey.

1.The geese fly in a "V" shape, which is a labor-saving flight mode that improves the flight ability of the 71 compared to the solitary flying geese.

2.When the geese fly in line, they provide an updraft for the geese behind them, and fan the surrounding air into an upward and forward airflow. When the geese left the group, they couldn't use the air currents to help, so they quickly got tired.

3.Without the encouragement of their companions, it is impossible for the wild geese to reach the south alone.

4.Outliers of geese.

A flock of geese will fly to a warm place for the winter. Their neat procession resembles the word "man" written in the sky.

One day, a young wild goose suddenly left the group and flew away on its own. As it flew, it thought, "Why do I have to stand in line?"

How unfree! "It flies, it flies. Gradually, it felt strained and its body became heavier and heavier.

At this time, it regretted that it should not have left the collective.

At this moment, an old wild goose flew to pick it up, and it asked strangely, "Why can't you fly when you leave the team?" ”

The older geese kindly told it: "Everyone lines up to fly, and the air around them is fanned up and forward, and through this air flow, each wild goose can fly with a little effort." You leave the party and can't use the air currents to help, so you get tired quickly. ”

The young geese understood, and it followed the older geese to catch up with the procession.
