Vliv konspecifické varovné vokalizace na formu a intenzitu antipredačního chování ťuhýka obecného (\kur{Lanius collurio}) / The effect of the conspecific alarm vocalization on the form and intensity of antipredator behaviour of the Red-backe Shrike (\kur{Lanius collurio})

Description

I examined the effect of the conspecific mobbing call of the Red-backed Shrike (Lanius collurio) on nest defence against arial predator (kestrel). I used a playback experiment in the presence of a dummy of kestrel (Falco tinnunculus) in two variants either with nature look or with adjusted key features (pigeon beak, claws and eyes), and pigeon (Columba palumbus) as a control. Shrikes were attracted by the mobbing call and arrived to their nests faster. Only the modified kestrel was attacked more likely in the presence of the playback, that suggests possible function of the mobbing call as a cue for social learning of predator recognition.
