Tamás, Enikő Anna & Kalocsa, Béla. (2006). The diet of young's and feeding places of Black Storks Ciconia nigra in Gemenc. BIOTA 7, 1-2: 103-108.
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.

Hampl R., Beran V. & Dolata P. T. (2007) 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]. Sylvia 43: 165–172.
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.

Hampl, Radek & Bures, Stanislav & Baláž, Peter & Bobek, Miroslav & Pojer, František. (2009). Food Provisioning and Nestling Diet of the Black Stork in the Czech Republic. Waterbirds 28, (Mar 2005): 35-40.
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 analysed. 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.

Maciej Kamiński, Jerzy Bańbura, Bartosz Janic, Lidia Marszał, Piotr Minias, and Piotr Zieliński Intra-Seasonal and Brood-Size Dependent Variation in the Diet of Black Stork (Ciconia nigra) Nestlings, Waterbirds 41(3), 268-275, (1 September 2018). https://doi.org/10.1675/063.041.0306
Nestling diet and parental provisioning rate are important determinants of reproductive success and future offspring performance in birds. The diet of Black Stork (Ciconia nigra) nestlings was characterized and tested for intra-seasonal and brood-size dependent variation in the type and mass of prey provisioned to the brood. Data were collected on 576 prey items from 45 Black Stork broods in central Poland during 2005–2016. Black Stork nestlings were provisioned almost exclusively with fish and amphibians; the proportion of invertebrates in their diet was marginal. Fish were a dominant component of nestling diet, comprising up to 65% of prey items and over 85% of total prey mass. Common spadefoot tadpoles (Pelobates fuscus), weatherfish (Misgurnus fossilis) and Prussian carp (Carassius gibelio) were among the most abundant prey. Black Storks foraged on relatively small prey, with an average length of 101.4 ± 1.5 mm (n = 576) and an average mass of 13.8 ± 1.0 g (n = 550). Larger broods were significantly more often fed with amphibians and with lighter prey. As the season progressed, the probability of preying on amphibians increased. This study provides evidence for Black Stork provisioning effort optimisation mediated by selection of smaller, but easier to catch and handle prey, such as common spadefoot tadpoles.
