. The Canadian field-naturalist. 1999 Burnett: Chapter 3: Working with Birds 41. Concern over declining populaTOns""6f the Black Duck in eastern Canada led to a decade of concentrated banding and research on this species between 1981 and 1991. One of the princi- pal participants in this work was biologist Myrtle Bateman, shown here at a 1985 field camp at Indian House Lake, Labrador (Photo credit: K. Dickson). Cooke with the William Brewster Award for his leadership of "the most meritorious body of work on birds of the Western Hemisphere published during the previous ten calendar years.'"^^ Cooke left the La Perouse Bay project in 1993, but Snow Goose research has continued to be an active field. In recent years, the more southerly populations of this species expanded rapidly. At La Perouse and Eskimo Point and many other breeding locations, the increase in the number of nesting pairs has out- stripped the carrying capacity of the range. Hugh Boyd, now Scientist Emeritus at the National Wildlife Research Centre, has followed this phenom- enon since the 1970s: In the southern locations, the geese are devastating large portions of their nesting grounds. That sort of damage might recover quite quickly in a temperate climate, but in the Arctic, once you chew up a grazing area, it may take a hundred years to regenerate. When Lynda Maltby and I were looking at Snow Geese in the high Arctic, it was obvious that those northern geese had adopted a somewhat nomadic lifestyle. They return to a different nesting site each year, whereas the southern geese return to the same site year after year. I think the southern geese nesting around Hudson Bay used to do the same thing. The trouble is that now there are so many geese that there aren't the unoccupied spaces to move to. When I was flying in the north in the early 1970s, we looked at large parts of Baffin Island that looked perfectly good in July and August but had no geese. When I was back there in 1988 and
