Sean Boyd's doctoral thesis investigated the interaction between Lesser Snow Geese and bulrush on the Fraser and Skagit River deltas. He documented the abundance and distribution patterns of geese within and across years, the growth ecology of bulrush within and across years, and the long-term interaction between the grubbing impact of the geese and the re-growth potential of bulrush. He worked as a habitat biologist with the Canadian Wildlife Service of Environment Canada from 1980-83. From 1983 to the present, he has worked with a number of colleagues and students on a variety of migratory bird projects: eg., winter ecology and demographics of Snow Geese, winter and migration ecology of Brant Geese, abundance and distribution of Trumpeter Swans, population demographics and behavior of Harlequin Ducks, habitat interactions and natal return rates of Barrow‰s Goldeneye and Bufflehead, distribution and demographics of moulting Surf Scoters, migration ecology and abundance of Eared Grebes, nesting habitat requirements of Marbled Murrelets, and at-sea foraging distributions of Cassin‰s Auklets. Many of his projects are long-term in nature and involve the use and refinement of marking protocols, especially radio-telemetry. The research is necessarily multidisciplinary and international in-scope. The objective is to provide scientific advice necessary to conserve migratory bird populations and their habitats in Canada, the U.S.A., and Mexico. He became a Research Scientist in 1997 and an Adjunct Professor in the Biology Dept. of Simon Fraser University in 1998. He serves on advisory committees of graduate students affiliated with the Canadian Wildlife Service Chair of Wildlife Ecology at Simon Fraser University and, to date, has been an active member of three PhD and six MSc graduate student committees.
