Sažetak
Wintering ornithofauna of Anatidae was researched on four carp fishponds in the Drava River tract: "Našička Breznica fishpond", "Grudnjak fishpond", "Donji Miholjac fishpond" and "Podunavlje fishpond". The data were collected during a ten-year mid-winter waterbird count, from January 1987 to January 1996. During the Homeland War, from 1992 to 1996, no count was taken in the Podunavlje fishpond, because this region was inaccessible to us. Registered are 22 Anseriformes species out of a total of 25 species that have contemporaneously wintered in Croatia as a whole. Anas platyrhynchos was the most common species in all four localities. The index of similarity ranged between 41.4% and 56%. The highest species diversity was found in Donji Miholjac fishpond. The Shannon-Wiener diversity index ranged from 0.32-1.37. A globally threatened species - Aythya nyroca - was also recorded here. Recently, all four investigated fishponds are evaluated as Important Bird Areas and potential Ramsar Sites.
