| Description
| - Egg discrimination in hosts of the common cuckoo Cuculus canorus is frequently studied by experimental parasitism, using model cuckoo eggs. We compared egg rejection behaviour of the great reed warbler Acrocephalus arundinaceus to either model cuckoo eggs made of plastic or painted real host eggs. In the present study we showed 96% average rejection rates against these egg types when they were applied in multiple experimental parasitism, causing a more predictable output for rejection behaviour. Hard plastic eggs and painted real eggs were rejected at similar frequencies, and videotaping revealed that model eggs caused extra work for great reed warblers. Most experimental eggs of either type were ejected within one day after the introduction of the eggs, indicating that hosts made their rejection decision quickly. Our observations suggest a lack of plasticity in the mode and timing of ejection behaviour towards experimental cuckoo eggs of different types in great reed warblers.

- Rozpoznávání vejce hostitelem kukačky obecné je běžně studováno experimentálním přístupem. Srovnávali jsme odmítání parasitického vejce vyrobeného z umělé hmoty a reálného. Vícenásobná parasitace positivně ovlivnila rozpoznání a následné odstranění z hnízda. Většina vajec byla odstraněna během jednoho dne, což indikuje rychlou reakci. Naše pozorování naznačují nedostatek plasticity ve způsobu odstraňování původem odlišných experimentálních vajec. (cs)
