Abstract: The aims of this study were to determine the distribution of waterfowl, shorebirds, birds of prey and songbirds, and estimate the amount of land required to support these populations in the vicinity of Boundary Bay, British Columbia. The estimated amount of food in Boundary Bay was insufficient to provide the energy needs of all American Wigeons (Anas americana), Northern Pintails (A. acuta) and Mallards (A. platyrhynchos) after autumn. Large populations of these ducks remained in Boundary Bay during day and night in autumn and flew to farmlands to forage at night through the winter. In the Bay, they ate mostly intertidal invertebrates, marsh plants, algae and eelgrass (Zostera marina and Z. japonica). In farmlands, they ate wild seeds, grasses, corn, potatoes, cabbage and insects. Over three quarters of the farmlands were used by the three duck species with especially large concentrations near the northwest shore of Boundary Bay along the Serpentine and Nicomekl Rivers and south of Ladner Village.
