The evolution of nestling discrimination by hosts of parasitic birds: why is rejection so rare?

Original language description

Question: Why do hosts of parasitic birds defend against parasitic eggs but not nestlings? Data incorporated: Reported cases of parasitic chick discrimination or mimicry and all previously published explanations for the rarity of these phenomena. Analysis method: Contrasting the predictions of previous hypotheses and fitting available data from both parasitic and non-parasitic birds to assess the relative validity of each explanation. Results: None of the previously suggested hypotheses appears to provide a general explanation for the scarcity of chick discrimination. Various cognitive and behavioral traits potentially usable for discrimination of parasitic chicks are present in virtually all avian taxa, including host lineages, yet these traits are not used to reject parasites. Thus, low selection pressure imposed by rare parasites is the most likely general explanation for the absence of these adaptations in the context of brood parasitism. Based on this I predict that nestling discr

Czech description

Článek podává přehled známých případů diskriminace a mimikry parazitických mláďat, dále všech hypotéz, které vysvětlují, proč je toto chování tak vzácné a nakonec vlastní model, který - na rozdíl od všech předešlých hypotéz uspokojivě - vysvětluje pozorovanou distribuci odmítání mláďat v přírodě.
