. The Canadian field-naturalist. 24 The Canadian Field-Naturalist Vol. 113 panions in arms get together to reminisce among themselves. Science and Enforcement Knowledge was yet another critically important element of enforcement and one where the some- times disparate scientific and enforcement strengths of CWS could come together in a productive part- nership. In 1966, coincident with the announcement of a National Wildlife Policy (see Chapter 10), a mandatory Canada Migratory Game Bird Hunting Permit was introduced. This step, initiated in 1966 under the guidance of Denis A. Benson, enabled CWS to initiate two important surveys. One, the National Harvest Survey, was conducted through a questionnaire sent to selected permit holders and produced information on hunting activity and the demographic characteristics of the hunting popula- tion. The other, the Species Composition Survey, started in 1967. It was based on a sampling of wings and tails returned by permit holders and furnished data on the age, sex, and species composition of the annual kill. The statistical design of the harvest sur- vey was at the leading edge of questionnaire-based research. Developed by Amode Sen, then head of the CWS Biometrics Division, it represented an impor- tant contribution to research methodology.^^ As the world entered the computer age, the tools for analyzing harvest and population survey data became increasingly rapid and sophisticated. J. Stephen (Steve) Wendt, who joined CWS in 1976, played a key role in helping CWS to adopt and adapt the new information technology to the needs of con- servation and enforcement. Switching from manual to automated sorting streamlined the formerly tedious task of processing half a million migratory bird hunting permits every year. Other changes that Wendt initiated included a system for input, storage, and retrieval of bird banding data and permit records and an original technique for extracting data in rela- tion to particular geographic areas
