Recognition of warning signal jay (Garrulus glandarius) in roe deer (Capreolus capreolus)
Pacáková, Alena ; Obleser, Petr (advisor) ; Husinec, Václav (referee)
This elaboration focus on bioacoustics interactions between a deer/roubucke(Capreolus capreolus) living in our territory, which is highly hunted and a jay bird (Garrulus glandarius), which has abilities according to ingrained experiences and traditional folk superstitions hetero-specifically to warn against predators.
On territory of the Czech republic is a deer/roubucke one of the most widespread artiodactyl and a jay bird is one the most common birds. The acoustic communication between those two species plays a big role, but her research was paid only slight attention.
This elaboration focus on recognition is abilities of deer on warning signals received from jay bird. There was 39 records received, how roe deer reacts on jas is bird signals. All recording took place in area of Radotin in Prague. By using the sound system, there were playing control signals of magpie bird follow up with warning signals of jay bird. There were evaluated aspects like sex, bonnet, distance, size of the bunch and of curse their influences on timing of hunting season.
The outcomes helped us to closely understand of life of roe deer and their behavior when they recognize warning signals. The analysis provided us information that roe deer respond the same way to warning signals from jay birds as well as control signals from magpie birds.
Based on further outcomes of the elaboration, it is important to mention unsubstantiated correlations of received signals between sex and age of roe deer.
We assume that behavioral symptoms to warning signals are closely related to experiences of given individual roe deer.
