Boundary Bay, at the southern edge of the Fraser River delta, is the most important bay to migratory birds on the Pacific Coast of Canada (Butler and Campbell 1987). About one million birds use the bay each year. Many of these birds are ducks and shorebirds that arrive in autumn from northern breeding grounds and remain through the winter (Vermeer and Levings 1977, Butler and Cannings 1989). In addition, the high density of raptors in the farmlands adjacent to Boundary Bay is unrivalled on the British Columbia coast. Moreover, the Lower Fraser Valley, especially around Boundary Bay, holds the last remnant population of Common Barn-Owls in Canada.
