The Bald Eagle
The national bird of the United States is the Bald Eagle. The eagle is the symbol for freedom. At one of the early battles of the Revolutionary War, the noise awoke the eagles and they flew out of their nest and circled over the fighting men. The whole time, the eagles were screeching. It was said by a patriot that the eagles were "Shrieking for freedom". The eagle became the Nation's emblem on June 20, 1782, which was when the great seal of the United States was adopted.
It was also said that the eagle was chosen for our bird because of its long life, great strength and majestic looks, and because it was said to exist only in North America. The American Eagle is found on the silver dollar, the half dollar, and the quarter.
