The Canadian field-naturalist. 1999 Burnett: Chapter 8: Wildlife Toxicology 131 ization and expansion at the National Wildlife Research Centre but also in the designation of CWS staff in every region to be the "eyes and ears" of the toxics group.'^' Collectively, they formed a national network of wildlife toxicology information gatherers that added greatly to the understanding of how wildlife can be used to mon- itor environmental trends. During a period when many CWS programs turned to a strongly regional focus, the coUegial spirit linking biologists in the field with the specialists at the National Wildlife Research Centre sustained a strong sense of inte- grated national purpose and collaboration in wildlife toxicology. This spirit made it feasible, for example, for Pierre Mineau and Alain Baril, at headquarters, to launch an effective review of the impact of pesticides on wildlife in sloughs across the Prairies. As more CWS biologists across Canada took up the study of contaminants in wildlife tissues, the demands on the analytical resources of the National Wildlife Research Centre grew in propor- tion. In this regard, one important area of develop- ment was the CWS Specimen Bank, which now constitutes the world's largest assemblage of wildlife specimens available for toxic chemical analysis. Chemical analysis capabilities in the early 1970s had been relatively primitive. Many com- pounds that would be almost commonplace in the 1980s were scarcely known to exist as environmen- tal contaminants a decade earlier. Fortunately, CWS had started collecting and storing tissues for immediate and future analysis during the early DDT studies of the 1960s. Until the mid-1970s, most of these samples were stored, frozen, at the Ontario Research Foundation. The Specimen Bank became a special CWS resource almost by default, when Jim Learning got word from the Ontario Research Foundation advis- ing that the provincial facility would no longer have room to keep the g
