Sažetak
The Drava River is a large right-bank tributary of the Danube in south-eastern Europe. Wintering ornithofauna of Anatidae has been research on 12 localities on the Drava River in Croatia. The data have been collected during a ten-year period, from January 1987 till January 1996, as a part of the Mid-Winter Waterbird Count. 23 Anatidae species were noted out of a total of 25 species that have contemporaneously wintered in Croatia as whole. The highest numbers and the most common species were Anas platyrhynchos, followed by Aythya fuligula, Aythya ferina, Bucephala clangula and Anas crecca. The average of 15.023 individuals of ducks, geese and swans, annually winters on the Drava river, comprising 35.8% of the annual winter average for the whole Croatia, amoung up to 42.006 individuals. The similarity index of wintering Anatidae community structure was calculated according to Sorensen and it ranged between 2.35 and 100%. Diversity indices are also given.
