Abstract The feeding on aquatic invertebrates, intensity and efficiency of forage intake were studied at the Sivash lagoons in 1995–2002 by the example of 6 wader species (217 birds). The diet composition significantly varied from seeds of plants to different species of aquatic and soil organisms. The diet at Eastern Sivash was based on Polychaeta, at Central Sivash — on Crustacea and chironomid larvae (Insecta). Foraging intensity depended on the abundance of main prey and the size of prey item
