"The geese sound to the north and Yan flies to the south." Why do the geese go north? Why does Yan want to fly south? Where are they going?

In "The geese sound in the north and the geese fly to the south", both the geese going north and the geese flying south refer to their habits. The flight of wild geese to the north is related to the seasons. Yan flies south because he leaves the cold north to spend the winter in the warmer south. The place they are going to is not the south of our country as we understand it, but a place further away. The geese go north to breed their offspring

Winter is coming, and because of the cold weather in the north, there is little food for the geese to find. If they stay in the north, they may not be attacked by natural enemies and the geese will face the risk of extinction. Therefore, when winter comes, geese will fly south in groups. The temperature in the south is higher and warmer than in the north, and the food is more abundant. It is a wise choice for wild geese to fly south to spend a long winter. However, why do wild geese choose to fly south instead of spending time in the south? That's because winter temperatures in the south are more comfortable and it's easier for geese to find food, making it more suitable for geese to survive.

Only winter in the south is suitable for wild geese to survive. Most other seasons and climates in the south are not suitable for wild geese. Therefore, when winter turns to spring, the wild geese are ready to go north. Therefore, it is equivalent to the north being the long-term home of wild geese, while the south is just a tourist area for them. It is spring when the wild geese fly back to the north, a season suitable for breeding. With the arrival of spring, the north becomes sunny and the temperature is comfortable. In the spring in the north, the wild geese have fewer natural enemies and more food, which is suitable for the wild geese to survive, so the wild geese choose to settle in the north and breed their offspring. Swallows fly south to survive the cold winter without food

Swallows are also migratory birds. They are extremely sensitive to the impact of the coming winter in the north, so swallows have to carry out large-scale operations before winter. migration. All migratory birds are prone to extinction in cold weather and without food support, so migratory birds will choose places with suitable temperatures and sufficient food to spend the entire winter. However, the winter in the south meets these conditions, and then a large-scale southward migration of swallows occurs.

The swallows spend the whole winter enjoying the warm sunshine and mild weather in the south. When the winter ends and spring comes, it is time for the swallows to go home. This is the same as the wild geese going north. , swallows fly to their hometown to live and work in peace and contentment, reproduce and reproduce, waiting for the arrival of the next winter. In fact, swallows flying south will also analyze where there are more insects or flying insects. so that they can find food on their own. Where did Yanbeiqu and Yannanfei go?

The headquarter of wild geese is in the Siberian area, so when they fly back from the south, they return to the Siberian area. Where did they fly back from? There are two different routes for wild geese flying south: one starts from Northeast my country, passes through the Yellow River and Yangtze River basins, and then reaches the coastal areas of Fujian and Guangdong. Sometimes there are groups of wild geese that fly to the Nansha Islands to spend the winter; another one passes through our Inner Mongolia and Qinghai regions to Sichuan and Yunnan and other places, and some fly to farther away Myanmar or even India and other regions to spend the winter.

When everything recovers, these wild geese fly back to Siberia to breed and wait for the coming of the next winter; in winter, swallows fly from their homeland to the south to spend the winter, and most of the places they fly to are It is much farther to Southeast Asia or South Asia than to the southern part of our country. Sometimes they will fly to places close to the equator, such as South Africa, the Nansha Islands and other areas, and even farther to the southern hemisphere. .

Flying south is not the south of our country as we understand it, because the way swallows look for food is different from other birds. They like to catch insects and flying insects in the air. Therefore, flying south is not only a journey for the swallows to spend the winter, but also a journey to find food. They will complete the task of overwintering according to the distribution of insects. Whether geese go north or swallows fly south, it is a way of survival that migratory birds respond to seasonal changes.

When you see swallows passing by in large numbers, be sure not to disturb them, so as not to frighten them and cause them to fall out of the queue or delay their arrival. This is not only very important for the swallows, but also for the swallows. It is also very important for us humans and researchers who study migratory birds. Once a flock of migratory birds is disturbed, it will have a huge impact on later researchers studying them.

So when you see the migration of migratory birds, you must keep a distance and do not scare them maliciously. You can feed the migratory birds some appropriate food to supplement the energy they consume during flight to support them. Next round of flight. We must know that the existence of migratory birds can also bring benefits and convenience to us humans. Therefore, we must protect them well, keep them from harm, and protect the environment where they live. Let humans and nature coexist peacefully.
