In 1782, the bald eagle was chosen as the national bird of the United States because it is a bird of strength and courage, and was found all over North America and only in North America.
But a little· over 200 years later, the bald eagle had 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 was 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 the poison affects their eggs. The eggs have very thin shells and do not hatch. Eagles only lay only two or three eggs a year. 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 increasing. It now appears that the American national bird will survive and remain a symbol of strength and courage.
