Diet of migrating robins was studied on the Courish Spit of the Baltic Sea region by stomach flushing in the spring of 1997. In spring, the diet of robins mainly consists of invertebrates. The main prey objects (occurrence >25%) were coleopterans (firstly, Carabidae, Curculionidae, and Staphylinidae), ants, myriapods, and spiders. Birds collected them in the litter and on the soil surface. In autumn, dipterans and hymenopterans were consumed more rarely. No differences in the diet of fat and lean birds, as well in their mass were found. A strategy of spring migration of robins is discussed related to their foraging.
