Before European settlers first sailed to America’s shores, bald eagles may have numbered half a million. They nested in forty-five of the lower forty-eight states.
Four years before the bald eagle was listed as an endangered species in 1967 there were fewer than 500 breeding pairs in the lower forty-eight.
