The Bald Eagle is the living symbol of a nation — and its comeback from the edge of extinction is one of conservation's great triumphs. Found across North America, Bald Eagles nest near large bodies of open water with abundant fish. Eagles mate for life and return to the same nest year after year — adding sticks until nests can weigh over a ton. In flight, that flat-winged soar on a six-to-seven-foot wingspan is unmistakable.
