Black storks are having a devastatingly bad breeding season
At the end of June 2022, the Nature Protection Guard Service of the Hortobágy National Park Directorate began monitoring the breeding success of the black stork population nesting in the Central Tisza Landscape Protection District.
Among the known nesting sites that have been occupied since spring, the pairs did not start nesting at several nests. In other cases, nestlings were destroyed during the hatching period or at a young hatchling age. In the tidal forests of the Tisza, only two of the 16 nests managed to find a chick, the National Park announced on its Facebook page.
As they said, the background of the extremely poor breeding results could be the insufficiency of the available food. Even though the winter and spring floods flooded the deeper areas of the wave field, filled the cubicles and backwaters, the dry, rainless period since the end of the summer of 2021 significantly decimated the population of amphibians and other aquatic organisms that form the food base of the black storks.
Surprisingly, nestlings with three hatchlings were found at some Black storknests , but the number of unsuccessful breeding pairs was also high, they wrote. The few successful Black stork pairs all spawn near small bodies of water and canals with locally favorable conditions. The successfully hatched chicks were provided with marking rings suitable for unique identification by the conservation guards.
The participants of the Ifjú Kócsagőr program also helped check the nests and ring the chicks.
