Název v původním jazyce

Consistency in egg rejection behaviour: responses to repeated brood parasitism in the blackcap (Sylvia atricapilla)

Popis výsledku v původním jazyce

To evaluate host responses towards repeated brood parasitism we experimentally parasitized and videotaped blackcap nests in 2 consecutive trials. The most common response in both trials was ejection. The general method of ejection was puncturing. In 9.8%of identified ejections, already punctured eggs stuck to abdominal feathers of incubating birds and were carried out of the nest. Females were responsible for the majority of ejections in both trials and their response time was shorter. Blackcaps exhibited consistency in the sex responsible for egg ejection over the two trials; but in five experiments individuals changed their behaviour. Repeatability for responses within the nest was very high. In ejections accomplished by the same bird, response wasquicker in the second trial, indicating the presence of certain learning abilities. Our results suggest that cuckoo hosts are quite consistent in their responses towards alien eggs when parasitized repeatedly within one breeding attempt.
