| dc.description.abstract-translated | The way, how birds discriminate and categorize their predators exactly, hasn't been known yet. More theoretic conceptions try to explain the mechanism of the categorization, one of them is the feature theory. The theory is based on that object is a compound of neutral and key features. We decided to examine this theory under labor conditions. We tested yellow expressive eyes of a predator, sparrowhawk, as a key stimul for recognition of predator by tits (Parus major). We used wooded dummies of the predator - sparrowhawk (Accipiter nisus) and a nonpredator - pigeon (Columba livia f. domesticus) and made chimeras between those two type that differed in eyes. Our results showed, that eyes really could be a key feature and it may works in a combination with other key stimuli. | eng |
