David N. Nettleship was a Senior Research Scientist with the Canadian Wildlife Service (retired 1998). His northern researches began on Common Snipe in lower James Bay with Dr. Leslie M. Tuck, followed by his own work on Ruddy Turnstones and Red Knots on Ellesmere I., and more than 3 decades studying northern seabirds. His main research interest is the reproductive ecology of colonial seabirds, particularly the Alcidae. Dr. Nettleship received a B.Sc. in biology at Sir George Williams University (now Concordia), Montreal, in 1965; M.Sc. in biology at University of Saskatchewan, Saskatoon, in 1967; and Ph.D. in zoology at McGill University, Montreal, in 1970. He was a research fellow at Oxford University (Edward Gray Institute of Field Ornithology and Animal Behaviour Group of the Zoology Department) in Oxford, England, from 1970 to 1971. Late in 1971, Dr. Nettleship officially joined the Canadian Wildlife Service to establish and head a formal research program on the ecology of seabird populations in arctic and eastern Canada which he continued to direct until his retirement in 1998. He is a Fellow of the American Ornithologists’ Union, past Chairman of the International Ornithological Congress (IOC) Standing Committee for Seabird Research (1985–1998) and Member of the IOC Committee, and is an associate editor of The Auk, Journal of Marine Ornithology, and Waterbirds; he has served as President of both the Waterbird Society and the Society of Canadian Ornithologists, and as Co-Chairman of the Canadian Committee for the International Biological Programme Conservation TerrestrialTundra (Panel 9). His publications include 9 books on the ecology and conservation of fauna and its habitats, more recently Seabirds on Islands: Threats, Case Studies, and Action Plans 1994), The Double-crested Cormorant: Biology, Conservation, and Management (1995), and Biology and Conservation of Forest Birds (1999). He is deeply committed to the development of land-use policy to protect biologically important marine and terrestrial sites in Canada and is active in several nongovernmental organizations, including Bird Studies Canada and the Quebec Labrador Foundation.
