Abstract

The objective of this study was to determine prey consumed by Red Knot (Calidris canutus). We analyzed 30 faeces and 2 pellets gathered in February 2002 in San Julián Bay, Santa Cruz Province, Argentina. The birds fed upon the clam Darina solenoides (90% of the faeces) and upon an undetermined amphipod species (40%). Perimeter of the maximum size of ingested clam did not overcome 30 mm, threshold limit of prey size that can be ingested by Red Knots. Mean faeces biomass was higher than those found in other locations.
