"To some, he was "Professor Nuts Peterson, " but to the world he was Roger Tory Peterson. For the birds: the life of Roger Tory Peterson tracks this American artist, activist, and passionate bird lover from his days as a child, to art student, to creator of the Peterson Field Guides, to global environmentalist. Peterson's guides were revolutionary--simply written and drawn for everyone to enjoy the birds, animals, and plants of the outdoors. Millions of copies have sold to date. Author Peggy Thomas and artist Laura Jacques worked closely with the Roger Tory Peterson Institute in Jamestown, New York, to create the first children's book about this great naturalist."--book jacket.
