“…Thanks to this, the updated list of Yom-Tov (2001) twenty years later already contained 234 species. Since then, intraspecific nest parasitism has been observed in some further species: Pied Avocet (Recurvirostra avosetta) (Hötker 2000), Northern Flicker (Colaptes auratus) (Bower & Ingold 2004), Song Sparrow (Melospiza melodia) (Latif et al 2006), Black-headed Gull (Larus ridibundus) (Duda & Chectnicki 2012) and Common Redshank (Tringa totanus).…”

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.

“…Among the 234 species listed by Yom-Tov in 2001, 41 are regular, occasional or former (extinct) breeders in Hungary. Based on publications since, I have added Pied Avocet (Recurvi rostra avosetta) (Hötker 2010) and Black-headed Gull (Larus ridibundus) (Duda & Chectnicki 2012) to Yom-Tov's list.…”

“…One aspect that may complicate the use of egg morphology indices such as MED to identify parasitized nests is the relatively high heritability of egg size (reviewed by Christians ), coupled with the finding that hosts and parasites are often related as has been found for example in common goldeneye Bucephala clangula (Andersson and Åhlund ), common eider Somateria mollissima (Andersson and Waldeck ), Barrow's goldeneye Bucephala islandica (Jaatinen et al ) and common black‐headed gull Croicocephalus ridibundus (Duda and Chętnicki ). Given the high heritability of egg size, relatedness between the host and the parasites may make the MED method less efficient in detecting CBP (see also Roy et al ).…”

Egg morphology fails to identify nests parasitized by conspecifics in common pochard: a test based on protein fingerprinting and including female relatedness

Conspecific brood parasites lay eggs in nests of other females of the same species. A variety of methods have been developed and used to detect conspecific brood parasitism (CBP). Traditional methods may be inaccurate in detecting CBP and in revealing its true frequency. On the other hand more accurate molecular methods are expensive and time consuming. Eadie developed a method for revealing CBP based on differences in egg morphology. That method is based on Euclidean distances calculated for pairs of eggs within a clutch using standardized egg measurements (length, width and weight). We tested the applicability of this method in the common pochard Aythya ferina using nests that were identified as parasitized (39 nests) or non‐parasitized (16 nests) based on protein fingerprinting of eggs. We also analyzed whether we can distinguish between parasitic and host eggs in the nest. We found that variation in MED can be explained by parasitism but there was a huge overlap in MED between parasitized and non‐parasitized nests. MED also increased with clutch size. Using discriminant function analysis (DFA) we found that only 76.4% of nests were correctly assigned as parasitized or non‐parasitized and only 68.3% of eggs as parasitic or host eggs. Moreover we found that MED in parasitized nests increased with relatedness of the females that laid eggs in the nest. This finding was supported by positive correlation between MED and estimated relatedness in female–female pairs. Although variation in egg morphology is associated with CBP, it does not provide a reliable clue for distinguishing parasitized nests from non‐parasitized nests in common pochard.
