The paper shows features of distribution based on regular captures and measurements since 1986 on two sites of Sivash (Central and Eastern), which are different in their hydrological regime and composition of forage macrozoobenthos. Shorter-billed males reliably prefer Central Sivash for storage of fat reserves at the expense of feeding on larvae of chironomids and possibly the brine shrimp. For longer-billed females it is more profitable to concentrate on Eastern Sivash, where they prefer to feed on polychaete worms. On basis of size characteristics of the captured birds and their time dynamics, the paper considers suggested terms of passage of different subspecies and populations of the Dunlin across the Azov-Black Sea coast of Ukraine. Also differences in age composition of migratory waders on different sites of Sivash are shown compared to other water bodies of the near Black Sea area.
