Recent changes in waterfowl hunting effort and kill in Canada and the USA / by H. Boyd. : CW69-9/175E-PDF
"Estimates based on responses by hunters to the Canadian and American waterfowl harvest surveys in the four hunting seasons between 1983-84 and 1986-87 show that the number of active waterfowl hunters continued to decline, as did the reported kill of ducks. The kill of geese had been increasing between 1974 and 1982; it is no longer increasing in Canada and has decreased greatly in the USA. Canadian waterfowl hunters continue to be more successful, on average, than US hunters"--Abstract.
