Název v původním jazyce

Eviction behaviour of the common cuckoo Cuculus canorus chicks

Popis výsledku v původním jazyce

During the coevolution between brood parasitic birds and the hosts, each has evolved a variety of mechanisms. Nestling competition for food among nestmates was probably such efficient selective pressure that eviction behaviour, i.e. pushing out of the eggs or nestlings, to have evolved in some obligate brood parasites. We studied the eviction behaviour of common cuckoo Cuculus canorus chicks by video recording at nests of great reed warblers Acrocephalus arundinaceus and reed warblers Acrocephalus scirpaceus. There were no differences between cuckoos reared by either host in hatching mass and age at first eviction. However, mass at eviction had a significant effect on the timing of first eviction event. No significant difference in time required to evict was found between serial intranest eviction events for cuckoos raised by either host.
