Based on data available so far, it seems that Common Moorhens (Gallinula chloropus) rarely, but regularly lay one or more eggs in the nests of Common Little Bittern (Ixobrychus minutus). Three such incidents from Hungary are hereby added to the cases known to date. However, Common Moorhens do not only lay eggs in other species’ nests, but also in the nests of conspecifics, while other species may also parasitise the nest of Common Moorhens. The present study summarises these aspects.
