Paperback in very good condition. Crease to front cover. A definitive work on the ecology of the bald eagle…The Bald Eagle begins with a history of the species as we know it in North America, through periods of near extinction at the first half of the century from over-hunting and habitat destruction, its recovery as environmentalists began to protect it, its brush with extinction again in the 1950s with DDT, and its recovery once again to the present. -- Prince Edward Island Evening Patriot
