Název v původním jazyce

High synchrony of egg laying in common cuckoos (Cuculus canorus) and their great reed warbler (Acrocephalus arundinaceus) hosts

Popis výsledku v původním jazyce

Female common cuckoos Cuculus canorus lay eggs every other day and typically parasitise nests before the hosts complete their clutches. When cuckoos? laying strategy is well-synchronised with hosts? laying, the parasites? reproductive success may increase. In contrast, when parasitism frequencies are high, cuckoo females might be less able to find suitable nests of the desired stage and without any prior cuckoo eggs. Contrary to this prediction, we found high synchrony of laying patterns between cuckoosand their locally primary hosts, the great reed warbler Acrocephalus arundinaceus, under unusually heavy brood parasitism (ca. 64% parasitism frequency) in the Hungarian Great Plains. Although hosts' laying activities showed different temporal patternsin the two consecutive years studied, the cuckoos closely followed the hosts? laying patterns in each year. This occurred despite the arrival of cuckoos to the study site 2-3 weeks earlier than the great reed warblers.
