The bald eagle is the national emblem of the United States. Unfortunately, the very people who made this bird into an icon also put it at risk of extinction. The bald eagle has been the victim of pesticide use, poaching, and habitat destruction. Thankfully, conservation efforts and the banning of DDT have helped eagle populations recuperate. Breaking down the history of the bald eagle’s progress with a helpful timeline, this book educates readers about the issues facing our national symbol. They’ll learn about the animal’s unique ecological role in text accompanied by colorful photographs.
