How The Bald Eagle Become A National Symbol of USA?
Eagles perched high and only soars in the sky, unwilling to jump on the ground like the other animals. The eagle has a single target, a keen eye, an obvious flight path, and a single direction, and will swoosh down instantly. It knows what it wants and where its goals are. Therefore, many people believe that the eagle represents courage and strength, so the new United States chose it as its national symbol. So a bald eagle becomes the national emblem of the United States. This bald eagle, which symbolizes independence and freedom, has a shield-shaped national flag on its chest. Its right paw holds an olive branch representing hope for peace, and its left paw holds a sharp arrow of determination to defend itself. This pattern Forms the national emblem of the United States. The bald eagle is one of the most important symbols representing the United States.
The bald eagle, is a bird of prey in North America. It belongs to the class of eagles. Its head is white. The biggest feature is that it looks extremely heroic and sturdy in appearance. Coupled with the unique free and unrestrained nature of eagles, and its absolute status as a winner in fights with other birds, the "bald eagle" has the characteristics of freedom, bravery, strength, and victory. They are found throughout most of Canada, the entire continental United States, and northern Mexico. Their range of activity is usually in open water because of the abundance of food resources. They usually nest in old trees. Bald eagles eat mainly fish, but sometimes they also eat carrion, small mammals and other birds.
It is precisely because of these characteristics that the Americans elected it as the national bird of the United States. It is worth mentioning that the number of "bald eagles" that survived in the United States at that time was not as large as what we see today, and the number was very rare. After the United States identified it as a national bird, it carried out protection actions, relying on artificial breeding and other reproductive methods. Let the "bald eagle" race breathe and not go to the fateful path of being disappeared.
When the bald eagle was designated as the national bird of the United States in 1782, there were about 100,000 bald eagles in the continental United States except Alaska. However, the continuous development of the land after the founding of the United States has caused the habitat of bald eagles to decrease rapidly, and overhunting has led to a further decline in the number of bald eagles. In 1940, the U.S. Congress passed the Bald Eagle and Golden Eagle Protection Act, which prohibited the killing and trading of bald eagles, and strengthened the publicity for the protection of bald eagles among the people. After the law was enacted, bald eagle populations rebounded in many states in the early 1940s. Shortly after the end of World War II, the United States began to use pesticides such as DDT and PCB in large quantities in agricultural production. These pesticides enter the bald eagle's body through the food chain, softening the bald eagle's eggshell and making it impossible to hatch eaglets. In addition, the habitat loss of bald eagles caused by human activities has increased the threat to bald eagles. By 1963, there were only 417 nesting pairs of bald eagles left in the continental United States. The bald eagle's doom doesn't stop there. In recent years, scientists have found that the blood of bald eagles has significantly higher levels of toxic chemicals than other raptors. This is because bald eagles are at the top of a long food chain and are more vulnerable to environmental pollution. The reproductive organs and brain tissue of many bald eagles were damaged as a result. To make matters worse, a large number of embryos often die from an excess of toxic chemicals in the mother's body. The number of bald eagles has been drastically reduced as a result. At present, the United States is making great efforts to save the endangered bald eagle, and it has achieved great results.
