The tendency of people towards foreign travel can be felt from the beginning of civilization. People have repeatedly left their homeland in the name of climate change, to earn a living or to acquire all the steps of education. It has run from east to west, from north to south. Land, water or air travel from one's own land to another has gradually increased. People have sung over and over again like birds,

If that were the case

I'm like a bird

I fly all the time

That's how he made the model of the aircraft. Well, have people somehow learned the rules of this 'foreign travel' from birds? You can learn!

Birds arrived on Earth during the Jurassic period about 16 crores years ago. Being a social animal, living with birds is quite ancient. People have domesticated birds. Staying in one house without adjusting the pet. This innocent creature has come so close to man that people have started calling his beloved 'bird' in the metaphor! He wanted to keep the birds in the cage according to the natural behavior of human beings. But love does not have to be kept in a cage, it is as if the bird has repeatedly explained it. Birds have migrated to the Himalayas in need. From Siberia to the south, further south to this Bengal. Migratory birds in hints. We call the guest birds whom we cherish. Let us know the story of the beginning of these guest birds today.

Birds are traveling thousands of miles from one country to another. Although they are not very large to look at, especially if they do not have the same 'superiority' as humans, they are not less intelligent. The matter may sound exaggerated, but it is a coincidence.

A flock of birds going for a walk;

Birds have no airspace. Birds do not stop on the radar. They do not have the boundaries of country, time, borders like the horses of Mahin. There are about 1.5 million species of birds in the world. Many of these species move from one country to another at a certain time of the year due to necessity. So some birds fly 22,000 miles every year effortlessly abroad. In our country, the guest birds do not travel that far, but the distance they travel is not less. Most of the guest birds arrive across the snow-white Himalayas. These birds enter from the Ladakh in the foothills of the Himalayas via the Central Asian Indian Flyway.

They fly about 800-1,300 meters above sea level. The speed of small birds is about 30 kilometers per hour. They can fly about 250 kilometers day and night. Those who turn a little, they can fly at 60 kilometers per hour effortlessly. Surprisingly, these birds can accurately determine their own destination!

Now the question may be, how do these birds come from so far away every year? Do they not lose their way? Birds can recognize the path through the earth's magnetic field. Our planet has its own magnetic field, and birds have magnets naturally in their brains. It works in the same direction as a small compass. Many people think that because birds have something in their eyes, they can sense the magnetic field directly and can easily recognize the north-south direction. We don't see the Earth's magnetic field, the lines seem to be moving from south to north

Note that this magnetic field also plays a role in the beautiful natural light play called aurora at the North and South Poles.

Some birds recognize the path from the position of the sun and stars, making their own way. These birds sense the sun's ultraviolet rays. When the sun sets in Norway, it can point in the direction of the sun. Among the birds, those who understand science less, which means students are bad, can understand the direction in shortcuts by looking at the environment around them, such as rivers, mountains, roads, etc.

Thousands of guest birds can be seen in our haors, beels and chars as soon as the river air feels like winter. They migrate to the colder winters of the south to escape the severe winters of North Hampshire, Siberia or Antarctica in England.

There are also flying birds math!

There is a story about this. The story is: One day a boy noticed birds flying in the sky and noticed that the birds were flying in a strange way. It is true that the world has laid down enough rules for us; But what a rule for birds! Seeing the birds flying in the sky, the boy Leonardo Bonachi alias Fibonacci discovered a star and sat down. In this number, birds fly like the English letter 'V'. 1, 1, 2, 3, 5, 6, 13, 21, 34 ... follow this section. This number is later called Fibonacci or Fibonacci.

Interestingly, when the ducks walk in groups, they also follow these rules. Sunflower leaves are similarly decorated. Let's talk about the science of birds flying in this 'V' shape. It is very difficult for a bird to fly four and a half thousand kilometers continuously in the same way that they fly alone. Maybe not. Because not all birds have the same strength. Birds have to fly through strong wind pressure.

The bird on the far right in the picture above is the team leader. Of all the birds, he consumes the most energy, which means that the wind pressure is gradually increasing. The one who is next, he is spending a little less energy than his predecessors. The two birds that are just behind are using a little less energy than the previous bird. The same rule applies to each row, there will be no deviation from this rule. Birds in a particular row fly with less energy than before and then use more energy in the next row. After a while they will change their position in order. This is how the birds go through an incredible journey of thousands of miles.

Among these birds is the well-known guest bird of Bangladesh, the Northern Pintail; As well as clear water sand ducks, khaira chakachakki, carliu, bunohans, storks, heron, diving birds, kadakhocha, singing rain birds, rajsarali, patikut, gadwall, pintail, nardam subelar, common pochardal, etc. extinct. Notable.

Birds of various colors and vocalizations include swan, sand duck, lenja, chiti, sarali, duck, nilshir, butihans, khanjana, patari, jalpipi, pani murgi, north giriya, patibatan, kamanchil, cottonchil, baikal, piangang. Rangamuri, black swan, swan, peribhuti, chakhachakhi, giriya etc.

The answer to why guest birds come and go is very simple. When the winter comes in their own home, they can't stand it and move to other countries where the winter is relatively less. At this time there is a shortage of food in the winter areas. There is also snowfall. So no plants can grow.

And who doesn't know, the relationship between nature, plants and birds is quite intimate. Birds nest in trees and collect food from there. They cannot digest the fruit or flower seeds eaten again, so the seeds move with the stool. And where that stool falls, new trees grow. Thus nature has been reforested in a strange way. Where there is no one to plant trees, the birds reach. Birds are very environmentalist.

The reproduction of this species of Avis in the vertebrata subfamily of the Cordata period is a well-known process. Birds lay eggs and hatch into babies. But it is not possible to get baby birds just by dropping these eggs. After giving it (heat) for a certain period of time, the embryo is born from the embryo of the bird. We all know how to give this to a bird's egg. The temperature should be 38 degrees. In a cold country, it is almost impossible in the winter season. So the birds choose a nomadic life like the Arab Bedouin to save the new generation and keep the lineage in order.

As winter approaches, birds from the Arctic, Siberia, Europe, parts of Asia, and the Himalayas flock to less cold regions. Although spring does not come to Kolkata in West Bengal at the end of winter in the city of December, it does catch the spring in the West Mary of the world, spring time means the ice of the temperate zone begins to melt towards March-April, gradually the vegetation begins to grow. The birds then returned to their homeland
