Rozpoznávají sýkory kukačku obecnou (\kur{Cuculus canorus}) od krahujce obecného (\kur{Accipiter nisus})?

The thesis includes a review of the topic of brood parasitism, with focus on the most common European brood parasite, the common cuckoo (Cuculus canorus). Experimental part of the thesis tests the responses of two titmice species (Parus major and Cyanistes caeruleus), which have virtually no experience with cuckoo brood parasitism, to presented dummy of cuckoo adult. The visual appearance of the common cuckoo importantly resembles the Eurasian sparrowhawk (Accipiter nisus), and it is supposed that this similarity protects cuckoo from attacks of adult host birds. Thus I tested the theory that titmice mistake the cuckoo for the sparrowhawk, which affects their nest defence behaviour
