Abstract

The Mosoni Plain Natura 2000 site is one of the most western nesting sites of the strictly protected Red-footed Falcon (Falco vespertinus) in Hungary, and the Common Kestrel (Falco tinnunculus) is the most common nesting bird of prey in the area. The breeding success of these two species, which do not build nests, can be greatly enhanced by the installation of good quality and properly placed artificial nests boxes. Monitoring of the artificial nest-boxes was previously not regularly and entirely conducted. However, from 2019 onwards, the now nearly 100 active nest-boxes are being regularly monitored, recording nest occupancy, clutch size and fledging data for Red-footed falcon, Common Kestrel, as well as for the Long-eared owl. The presenent paper summarises the nesting records of these three species on artificial breeding sites on the Moson Plain. During the period 2019–2023, we observed a total of 12 Red-footed Falcon breedings, 7 of which were in artificial nestboxes. On average, 3.0 chicks were successfully fledged from the boxes. Regarding Common Kestrel, a total of 121 breedings were recorded in nesting boxes, of which more than 80% were successful. On average 3.84 chicks fledged per nest box. During the 5 years of the study, a total of 14 pairs of Long-eared Owl breeding were associated with artificial nest-boxes, of which 10 proved successful. A total of 35 chicks fledged successfully.
