The wings are 2.3 meters long, the golden eagle of the macho player, but the large raptor has fallen into the dirge of extinction

Golden eagles are the best-known large birds of prey in the northern hemisphere, with wingspans up to 2.3 meters wide. With their enormous size and strength, these hunters can capture and kill prey twice their weight. There was a shocking piece of news about the golden eagle. It was about the golden eagle attacking two men for "revenge for eating children" and forcing one of them to move for two years. After receiving 40 stitches, he was still frequently attacked by golden eagles and was forced to move. The target of the golden eagle turned to Yang Haijun, who was eating young birds with him. He was seriously injured by the golden eagle twice in a short period of time. How did such a ferocious animal grow in its youth?

The overlord attitude formed since childhood

First of all, let us understand something about the reproductive process of golden eagles: golden eagles mature for a long time, and they usually only reproduce for the first time when they are six years old. Between early March and early April, the significantly larger females will lay one to three eggs, which take a full six weeks to hatch. Young golden eagles stay in the nest for two and a half months. Due to the different growth rates of different individuals, some chicks can continue to stay in the nest for several weeks after that, and are fed by the parent birds. During this time, these little golden eagles have to learn to hunt by themselves. Although golden eagles will choose to nest on cliffs or higher trees, their nests are not completely safe. Parent birds work hard throughout the year to defend their range from encroachment by other carnivorous birds. Young golden eagles learn many hunting techniques as they grow up. They learn to hunt animals such as rabbits and pheasants. Golden eagles learn quickly. After 20 repetitions, the little ones will become familiar with hunting skills. As they grow older, these raptors will become more and more more wise. It is precisely because of the environment in which it lived since childhood that the golden eagle has gradually grown into an extremely ferocious aggressive animal. Golden eagles will capture any animal they can attack in their vicinity, and they are mainly found in northern Eurasia. In summer, the food of golden eagles is extremely abundant, and civet cats, rabbits and grouse will become the food of golden eagles. With its size advantage, golden eagles also like to catch young chamois, deer, reindeer, roe deer, fox, badger and lynx. Few birds of prey are capable of directly killing large herbivores, and the golden eagle is definitely an exception. When hunting, golden eagles usually stop on trees or rocks to wait. After finding the target, they often rush towards the prey by ramming to kill it. For larger mammals, golden eagles follow their prey closely in a sliding descent. Golden eagles prey on sika deer The above is what the editor first saw, heard and understood about golden eagles. However, now such a ferocious "Overlord" is facing a serious crisis of chasing and killing, and a stronger "Overlord" has launched an attack on them. The tragic hunter, such a ferocious golden eagle, has almost no rivals in the flying world, but now has the exact opposite situation? In recent years, the living conditions of golden eagles are not optimistic, especially in the rapidly urbanized European regions. The ferocious and powerful characteristics of golden eagles brought them bad luck. As early as the 17th century, golden eagles were used as competitors by hunters throughout Europe. Hunters waged an unprecedented war of annihilation against the majestic bird, using guns, iron cages and poisonous baits against the golden eagles, and half-built nests were taken or destroyed. Human activities have seriously affected the survival of golden eagles. Due to their long maturation period and low egg production, it is difficult for the golden eagle population to recover in a short period of time. The European region is the most severely hunted area for golden eagles: in Germany, for example, in the 17th century, golden eagles disappeared in the Thuringian Forest and the Erz Mountains in Germany. There were no traces of golden eagles in the Harz Mountains around 1750 and in the Swabian Jura around 1800. The last pair of golden eagles hatched in the Black Forest in 1816 and in Brandenburg in 1876. In 1887, the last golden eagle nest in Pomorie was also destroyed, and only the Bavarian Alps still had golden eagles in Germany, because the golden eagles there built their nests on the cliffs that people could not reach. The eagle has survived there to this day. The situation of golden eagles in other countries is definitely not optimistic. For example, the golden eagles in Iceland went extinct in 1910. It was not until the 1850s and 1860s that, like other birds, the hatching rate of golden eagles dropped sharply because of the pesticide DDT, and humans did not realize the seriousness of the situation. Immediately after this incident, the golden eagle became an endangered species in desperate need of protection. Many countries have not only banned the use of DDT, but have also adopted strict protection measures for golden eagles. The "Washington Convention" lists the golden eagle as a species in Appendix 2, and my country's protection of the golden eagle is more advanced, and the golden eagle is listed as a first-class key protected animal. More and more countries are enacting policies to protect the raptor. Since then, the number of golden eagles in many countries has gradually increased, or at least remained stable. In Europe, golden eagles are no longer the target of hunters, and some small golden eagles that fly out of the Alps into the plains out of curiosity will not be shot, and they can fly back safely.

Summary

When some European countries banned DDT and killed golden eagles, the golden eagle population began to recover, but the recovery rate was extremely slow. Despite the protection of humans, the golden eagle still has to overcome some difficulties to restore the population. Generally, golden eagles are built on cliff walls or high trees that Li and other mammals cannot climb. Some bird researchers in Sweden have found that golden eagles generally build their nests in large trees with an average age of 320 years. Such an old tree is still very rare in Europe, because forest managers will cut it down and put it into use when it reaches 120 years old and up to 140 years old, which makes it impossible for some golden eagles to find suitable places to nest. Since there are very few cliffs in the plains, the golden eagles need to wait for a while to incubate there. Therefore, the recovery of the golden eagle population is very slow, and the policy of protecting the golden eagles must be continued for a long time.
