For centuries, people have admired eagles and adopted them as symbols of strength, bravery, and authority. Roman soldiers carried a golden figure of the eagle into battle. Russian and Austrian emperors used the eagle to project power and prestige. For thousands of years, eagle feathers have been rewarded as a high honor among Native Americans. In 1782, the Founding Fathers selected the bald eagle as the national bird of the United States, and it remains on the seal of the president.
