Distribution of birds in the intertidal portion of the Fraser River delta, British Columbia / Robert W. Butler, Richard J. Cannings. : CW69-5/93E-PDF
"The Fraser River delta supports more birds than all other estuaries on the Pacific coast of Canada. Bird populations in the delta have been estimated for mostly large segments of the delta such as riverine marshes and Boundary Bay. Savard’s (1985) study counted waterfowl at 19 sites around the delta in autumn and winter. However, there is no information on the numbers of all birds using the entire shoreline of the Fraser River delta around the year. The purpose of this study was to compare the monthly use by all birds of small segments of the Fraser River delta seaward of the dykes throughout the year"--Introd., p. 1.
