Food Provisioning and Nestling Diet of the Black Stork in the Czech Republic

The food composition, prey size, quantity of prey, feeding frequency and diurnal pattern in the feeding frequency of chicks of Black Stork (Ciconia nigra) were studied in six nests in the Czech Republic during the breeding seasons 1998-2003. Video cameras were used to record prey brought to the nests. Regurgitations and pellets were also analyzed. In total, 474 prey items were collected. Aquatic animals, mainly fish, prevailed in the nestlings’ diet. Six species of fish, undetermined frogs and snakes, two mammal species and eight insect species were found. Adults provisioned their young nestlings with smaller fish. The length of fish and total mass of consumed prey significantly increased with nestling age. No relationship between chick age and feeding rate was found. In total, each chick consumed 14-20 kg of food up to fledging.

The diet of young's and feeding places of Black Storks Ciconia nigra in Gemenc

We have been carrying out investigations of the feeding of Black Storks Ciconia nigra in the Gemenc area since 1996. We have collected data about the species and quantity of prey found near nests and thrown up by young during ringing; furthermore, we regularly observe Black Storks at feeding places as well. Based on these eight years’ data, the food and feeding place preference of the Black Stork can be determined (for this habitat, or for
this type of habitat). Main food of the Black Stork is fish, whereas the most important feeding grounds are temporary shallow floodplain waterbodies.

Potrava mláďat čápa černého (Ciconia nigra) v České republice a v Polsku - Nestling diet of the Black Stork (Ciconia nigra) in the Czech Republic and Poland

Food composition and prey size of Black Stork (Ciconia nigra) chicks were studied from regurgitations at 26 nests in the Czech Republic and Poland during 1977–2007. In total, 181 prey items were identified. Fish prevailed in the nestlings’ diet, but frogs and invertebrates were also present. Ten species of fish and two taxa of frogs were found. The average length of the fish was 12.8 cm. On average, chicks regurgitated 7.7 pieces of prey/nest. In nests with more than two prey items, mostly two species were recorded.
