Fred Shaffer worked for the Maryland-National Capital Park and Planning Commission for over 30 years and became interested in gulls by observing the large flocks that gathered each day at Schoolhouse Pond just outside his office. He enjoys observing gulls in all their diversity and plumages and has documented his gull observations from Schoolhouse Pond in Maryland Birdlife. He has studied gulls in their natural habitat across North America and photographed the many plumages of each species.
