5203 |a"Collections were made of three species of scoter ducks, white-winged, surf and black, Melanitta deglandi, M. perspicillata and M. nigra, wintering at two clam beaches in southern British Columbia. Analysis of the crop and gizzard contents showed these ducks were feeding primarily on bivalves in the intertidal area. The commercially-important littleneck and manila clams, Protothaca staminea and Tapes philippinarum, comprised over half the gut contents of scoters. It was estimated that a wintering flock of 200 scoters could remove 5.3 to 15.9 tonnes of littleneck and/or manila clams from these two beaches in a six month period"--Abstract, page iii.
