Host selection in parasitic birds: are open-cup nesting insectivorous passerines always suitable cuckoo hosts?

Popis výsledku v původním jazyce

How do potential hosts escape detrimental interactions with brood parasites? Current consensus is that hole-nesting and granivorous birds avoid brood parasites, like common cuckoos Cuculus canorus, by their inaccessible nest-sites and food unsuitable forparasites, respectively. Any open-nesting insectivorous hosts are believed to remain open to brood parasite exploitation which leads to the evolution of costly host defences like egg or chick discrimination. In contrast to this coevolutionary scenario,we show for the first time that a previously not studied but seemingly suitable host species escapes brood parasites. The Asian verditer flycatcher Eumyias thalassinus, feed newly hatched chicks entirely with beetles and grasshoppers. These are poor quality and hard to digest diet items that are rarely fed to own or cuckoo chicks by regular hosts. Indeed, chick cross-fostering experiments showed that these food items remained undigested by either cuckoos or other sympatric passerines cau
