- <p>The paper presents the results of a 2021 inventory of<br>selected breeding bird species at 16 fish pond complexes<br>located in the Stobrawski Landscape Park<br>(northern part of the Opolskie voivodeship). For the<br>majority of aquatic species, an assessment was made<br>of the size of the breeding population inhabiting the</p> <p>study area: Mute Swan Cygnus olor – 43–50 pairs,<br>Whooper Swan C. cygnus – 1 pair, Greylag Goose<br>Anser anser – min. 47 pairs, Goldeneye Bucephala<br>clangula – 18–25 pairs, Red-crested Pochard Netta<br>rufina – 1 pair, Common Pochard Aythya ferina<br>35–39 females, Tufted Duck A. fuligula – 42 females,<br>Gadwall Mareca strepera – 19–24 females, Great<br>Crested Grebe Podiceps cristatus 20–26 pairs, Bittern<br>Botaurus stellaris – 10 males, Little Bittern Ixobrychus<br>minutus – min. 1 pair, Marsh Harrier Circus<br>aeruginosus – 13–16 pairs, Bluethroat Luscinia<br>svecica – 1 pair. The results of the study showed that<br>the inventory area is an important nesting site for<br>many wetland bird species on a regional scale. The<br>biggest peculiarity of the area is the only regularly<br>inhabited nesting site of the Red-crested Pochard<br>in the Opolskie Voivodeship. The high numbers of<br>some species prove that extensive management of<br>fish ponds in the Stobrawski Landscape Park has<br>a positive impact on the preservation of populations<br>of many important and scarce waterbird species.</p>
