In 1782, soon after the United States won its independence, the bald eagle was chosen as the national bird of the new country. American leaders wanted the eagle to be a symbol of their country because it is a bird of strength and courage. They chose the bald eagle because it was found all over North America. Presently, the bald eagle has almost disappeared from the country. In 1972 there were only 3,000 bald eagles in the entire United States. The reason for the bird’s decreasing population is pollution, especially pollution of the rivers by pesticides. Pesticides are chemicals used to kill insects and other animals that attack and destroy crops. Unfortunately, rain often washes pesticides into rivers. Pesticides pollute the rivers and poison the fish. Eagles eat these fish and then the eggs eagles lay are not healthy. The eggs have very thin shells and do not hatch. Because many of the eggs did not hatch and produce more eagles, the number of eagles quickly became smaller. Today, the American government and the American people are trying to protect the bald eagle. The number of bald eagles is slowly increasing. It now appears that the American national bird will survive.
