“…Therefore, our results provide evidence that Coots could rely on the differences in eggshell pigmentation to recognize foreign eggs and evade the costs of brood parasitism. The recognition of own eggs might be particularly important in this species, because besides facing the odds of the occasional interspecific brood parasitism of the Moorhen, the Coot is also known to utilize this alternative reproductive strategy as a facultative intra-and conspecific brood parasite (Samraoui & Samraoui 2007, Haraszthy 2018.…”

“…Common Moorhens Gallinula chloropus (Moorhen hereafter) exhibit a highly diverse breeding strategy, ranging from monogamy to polygamy and polygyny, but are also notoriously brood parasitic (Gibbons 1986). Moreover, besides eggs dumped in the nests of conspecifics, Moorhen eggs were found within the clutches of Little Bittern Ixobrichus minutus, Eurasian Coot Fulica atra (Coot from hereafter), Grey Partridge Perdix perdix, Little Grebe Tachybaptus ruficollis, Black-headed Gull Chroicocephalus ridibundus and Ferruginous Duck Aythia nyroca (Engler 1983, David et al 2005, Meniaia et al 2014, Haraszthy 2018.…”

Differences in eggshell pigmentation pattern between Common Moorhen Gallinula chloropus and Eurasian Coot Fulica atra eggs

Facultative avian brood parasites increase their reproductive output by laying eggs in the nests of conspecifics or closely related species. The Common Moorhen Gallinula chloropus is a well-known facultative brood parasite that nests in wetlands, which are utilised also by a wide range of waterfowl, including the Eurasian Coot Fulica atra. The two species breed in similar habitats and have a similar egg pigmentation pattern; thus, the Coot can be a suitable host of brood-parasitic Moorhen. To study whether there is any discernible difference between the spotting pattern of Coot and Moorhen eggs, we compared the density of different sized spots on eggs of the two species. Our results show that Coot eggs have a significantly higher density of small speckles then Moorhen eggs, while the latter species has eggs with more conspicuous larger spots. Therefore, Coots can possibly rely on these differences in eggshell pattern to recognize and eject the brood parasitic Moorhen eggs.

Intraspecific nest parasitism has only recently received more attention from ornithologists. In 2001, Yom-Tov published a list of 234 species that had exhibited this behaviour. I have since found literature data on four additional species in which intraspecific nest parasitism has been observed. No such record has so far been published from Hungary. This study presents records on 25 species from Hungary and on one species from Croatia, out of which I have not found any reference for intraspecific nest parasitism in the literature for Cattle Egret (Bubulcus ibis), Eurasian Thick-knee (Burhinus oedicnemus), Black-winged Stilt (Himantopus himantopus), Collared Pratincole (Glareola pratincola), Mediterranean Gull (Larus melanocephalus), Little Tern (Sternula albifrons), Whiskered Tern (Chlidonias hybrida), Eurasian Roller (Coracias garrulus) and Eurasian Jackdaw (Corvus monedula). In addition to records from Hungary, for Black-headed Gull (Larus ridibundus) and Mediterranean Gull I also present observations from Slovakia, and for Common Shelduck (Tadorna tadorna) from Germany.

“…On 10 June 1979,Rékási (1980) found Little Bittern nests under three of the Purple Heron nests in the marsh at Madaras, one of which contained three white Little Bittern eggs and three speckled Common Moorhen eggs. On 29 May 2005, the nest I found in the reedbelt of the Hortobágyi-Fishponds had five Little Bittern eggs and a Common Moorhen egg(Haraszthy 2018). On 18 May 2017, I checked 191 Black-headed Gull nests out of approximately 500-600 at Fülöpszállás.…”

Cases of occasional interspecific brood parasitism and egg dumping in Hungary

There are numerous publications in the ornithological literature on mixed-species broods, i.e. on cases when a species lays some or all of its eggs into the nests of other species. This phenomenon, known as brood parasitism, has not yet been studied in Hungary. Here, I use the term brood parasitism, but I could not separate cases of egg dumping, a reproductive error by females. Based on literature and my own observations, I found evidence for interspecific brood parasitism in 28 species breeding in Hungary, not including the cases of the obligate interspecific brood parasite, the Common Cuckoo (Cuculus canorus). Only one of these belongs to passerines, while in the rest of the cases, this phenomenon occurred in representatives of non-passerine families. However, cases of brood parasitism and nest parasitism have to be treated separately. The latter refers to cases when a species occupies a nest, usually a nesthole or nestbox, already containing eggs of another species, and lays its own eggs next to the foreign eggs. The present study provides data on European Roller (Coracias garrulus), Northern Goshawk (Accipiter gentilis), Common Kestrel (Falco tinnunculus), Red-footed Falcon (Falco vespertinus), Eurasian Hobby (Falco subbuteo), tit species (Parus, Cyanistes, Poecile spp.), Eurasian Nuthatch (Sitta europaea) and Eurasian Tree Sparrow (Passer montanus), but in all likelihood the number of species involved is much higher.
