The bald eagle holds an olive branch on one foot and an arrow on the other, symbolizing peace and strong force. In peacetime, the bald eagle in the US national emblem will be changed to face the olive branch, and in case of war, the bald eagle in the US national emblem will be changed to face the arrow branch.
In 1982, President Reagan declared June 20 every year as the bald eagle day, in order to arouse the attention of the whole nation, which is enough to show the degree of his attention. As the national bird of the United States, the bald eagle has become one of the important symbols of the United States. Many badges have its portrait. The presidential emblem is a good example.
