Název v původním jazyce

Are blackcaps (Sylvia atricapilla) defending their nests also calling for help from their neighbours?

Popis výsledku v původním jazyce

One hypothesized function of conspicuous mobbing of intruders by bird nest owners is to attract neighbouring birds ("calling for help" hypothesis) or thirdparty predators ("attract the mightier" hypothesis). These may help the nest owners by distractingand/or attacking the mobbed intruder. To date, these hypotheses have been studied solely during the mobbing of predators. Here, for the first time, I have studied mobbing attraction in the context of brood parasitism. I experimentally tested the Blackcap(Sylvia atricapilla), a small passerine with a highly aggressive and conspicuous nest defence behaviour. I elicited the aggressive responses of Blackcaps by presenting stuffed dummies of the brood parasitic Common Cuckoo (Cuculus canorus) and controls near their nests. At 32% of the nests (n = 75), the responses of the Blackcaps to dummies attracted up to 15 birds per trial from 21 passerine species. Most of the attracted birds were heterospecifics and rarely participated in mobbin
