Klíčové znaky a prototypy ve vizuálním rozpoznávání predátorů - laboratorní experimenty se sýkorou koňadrou (\kur{Parus major}) / Key features and prototypes in visual predator recognition - laboratory experiments with Great Tit (\kur{Parus major})

Categorization of predators is fundamental for birds? life. However, the mechanism is not well explained yet. Two basic theories of categorization were tested in the laboratory conditions, where we have the possibility to focus on the behavior of each individuum. In the experiments we focused on the relevance of the key features and colour patterns. The responses of the Great Tit to variously modified dummies of Sparrowhawk were observed. The results confirm that the bird does not recognize the predator only on the basis of the key features and the colour patterns have a essential influence on the categorization. Categorization of the predator is a complex process and it cannot be explained only on the basis of one psychological theory. A combination of the key features and a prototype of a particular category learned throughout its life is probably used.
