Plot Summary:Everything about them is big. They are one of nature's largest raptors, with wings that can span eight feet, and nests that can weigh up to a ton. Unique to North America, the bald eagle is the continent's most recognizable aerial predator, with a shocking white head, electric yellow beak and penetrating eyes. Yet most people know little about it beyond its striking appearance. In the 1960s, the bald eagle was on the brink of extinction caused by the pesticide DDT and other human pressures. Following their protection as an endangered species, bald eagles have come roaring back. But even in the best of times, life in the wild for these birds is a surprisingly tough struggle. From the pristine wilderness of Alaska to the Upper Mississippi River Valley, American Eagle goes behind the scenes and into the nest to provide the ultimate bird's eye view into the private life of an American icon.
北美洲特有的白頭海鵰，是空中顯眼的掠食動物，牠有亮白的頭部、鮮黃的鳥喙與洞察萬物的雙眼。本片由榮獲艾美獎肯定並身兼養鷹人的尼爾瑞提負責掌鏡，來描述這傲人鳥類的故事。白頭海鵰的數量在1960年代早期跌落谷底，因為DDT的廣泛使用對鳥蛋造成傷害。在殺蟲劑禁用了一段時間之後，牠們仍面臨威脅。白頭海鵰與車輛、輸電線的相撞，使牠們深受其害。但最大的潛在危機，是每年為害大量白頭海鵰的金屬毒性。儘管因為和人類相鄰而居而危機四伏，但白頭海鵰的數量已經大幅回升，並且在2007年從美國聯邦政府瀕危物種名單上除名。白頭海鵰再度接管了北美高空。
