For several reasons, waders in the Wadden Sea face a large seasonal and annual variation in their food supply. Observations on a tidal flat in the Dutch Wadden Sea have shown that: (1) The average energy density of ten invertebrate prey species varies between 21 and 23 kJ.g-1 AFDW. In Scrobicularia...
