Speaking of birds with the deepest roots with human beings, I believe that the first reaction in many people's minds is swallows, because there are children's songs in primary school textbooks that read, "Little swallows, wear flower clothes, come here every spring", plus swallows belong to beneficial birds, and many people like it. But in fact, the bird most closely related to human life should be the sparrow, which is currently one of the most widely distributed, numerous and most common birds on the mainland.
However, some media have released news that the sparrows that are closely related to our daily lives are not actually native sparrows on the mainland, but the descendants of millions of sparrows imported from the Soviet Union in the last century, and if there are not a million sparrows imported from the Soviet Union, the sparrows may be extinct on the mainland.
Speaking of sparrow extinctions, it is necessary to mention the "Four Pests" campaign, which reached its climax in the winter of 1957 and the first half of the second year, including sparrows, flies, mosquitoes and rats.
To eliminate the four harms is mainly because at that time new China was just a few years old, all walks of life, waste to be rebuilt, especially agricultural production is relatively backward, the annual grain production can not even meet the needs of residents, some experts said that the sparrow is one of the important reasons affecting the lack of grain output, if the sparrow in the grain filling period to visit this land, then the grain in this land will appear a large number of grains, grain production will be greatly reduced, and if the sparrow in the milk ripening period of the grain to come, many places directly become bare. According to statistics, a sparrow needs to consume about 4.5 kilograms of grain every year, and if 1 million sparrows can be eliminated, the food saved is enough for 60,000 people to eat.
In order to protect food, the mainland has organized the "four pests" activities, although sparrows, flies, mosquitoes and rats belong to the same "four pests", but the way of life of each animal is different, flies, mosquitoes have obvious seasonality, the previous year was eliminated, the next year will make a comeback. And rats not only have super reproductive ability (they can mate all year round, they can give birth to 6-8 litters a year, each litter will have 4-8), but also have the ability to punch holes, although in addition to a long time, but the number of rats has not been greatly affected.
In order to complete the target of removing sparrows, at that time, men, women and children went into battle together, firecrackers were fired in unison in the streets, alleys, walls, and trees, bamboo poles and flags were waved together, forcing the sparrows to fly, and then combined with the comprehensive tactics of "bombing, hitting, poisoning, and digging", they dealt a heavy blow to the sparrows. Although sparrows were later removed from the four pests, the number of sparrows across the continent has been severely damaged and the number has plummeted.
Although the sparrow will eat a certain amount of grain, but the main food of the sparrow in addition to the grain there are pests in the field, eating grain is generally in the case of eating insects can not eat enough to do it, the reason is very simple, a plate of greens and a piece of meat in front of us, we must prefer to eat meat, only when the meat is not enough to eat, only reluctant to eat vegetables. Therefore, after the sharp reduction in the number of sparrows, crops everywhere have suffered more serious insect pests.
Some media on the Internet said that in order to speed up the pace of recovery of the number of sparrow groups on the mainland, the mainland imported millions of sparrows from the Soviet Union, and after the release, it supplemented the sparrow group, and after a long period of cultivation business, the current group of sparrows was obtained.
Many online media have analyzed the mainland's import of a million sparrows from the Soviet Union, but what I want to say is that this is an outright rumor. There are several main reasons:
1. Some people say that at that time, the four pests were removed by the mainland's domestic sparrow, and in order to restore the sparrow population, the continent imported from the Soviet Union was a tree sparrow. The actual situation is that since ancient times, the sparrows in the ancient continent are mainly tree sparrows, not domestic sparrows. The most obvious difference between the tree sparrow and the house sparrow is that the tree sparrow has a black spot on each side of the cheek, while the house sparrow does not. However, we can see from the propaganda map of the removal of the four evils at that time and the video at that time that the sparrows that were removed when the four pests were removed were all tree sparrows with black spots on their cheeks.
2. It can also be seen from the sparrows in ancient paintings that the most common sparrows in the ancient mainland were tree sparrows. For example, the sparrows in the works of the Five Dynasties and Ten Kingdoms Western Shu painter Huang Quan are all tree sparrows with black spots on their cheeks. The sparrows involved in other ancient paintings also have black spots on their cheeks. This can be explained by the fact that tree sparrows have existed on the mainland, rather than relying on imports from the Soviet Union.
3. According to the reports of the Internet, the time when the mainland may import sparrows is the time period when China and the Soviet Union are at odds, coupled with the serious shortage of labor population in the Soviet Union at that time, naturally the Soviet Union will not help us to do such a small thing as catching a million sparrows.
4, the Soviet Union to catch a million sparrows exported to the mainland is a big deal between the two countries, when the epidemic situation on the mainland of the millennium is more serious, Mongolia donated 30,000 sheep to the mainland caused a hot discussion on the Internet, even if the information at that time was not developed, newspapers and other media will also carry out a large number of reports, but whether it is the Soviet side or the mainland, there is no relevant report.
5, I believe that many friends have the experience of breeding sparrows when they were young, the temper of sparrows is very strange, as long as you keep it in a cage, it will not eat or drink until it starves to death.
Combining the above 5 questions and analyzing them, we can boldly say that the sparrows we see everywhere now are our native sparrows, and they are not at all the descendants of millions of sparrows imported from the Soviet Union.
