Breeding birds of fish ponds of the Stobrawski Landscape Park in the year 2021

The paper presents the results of a 2021 inventory of
selected breeding bird species at 16 fish pond complexes
located in the Stobrawski Landscape Park
(northern part of the Opolskie voivodeship). For the
majority of aquatic species, an assessment was made
of the size of the breeding population inhabiting the

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