How Do Predators Learn to Recognize a Mimetic Complex: Experiments with Naive Great Tits and Aposematic Heteroptera

Popis výsledku v původním jazyce

We tested the importance of innate wariness, avoidance learning, memory and generalization for the formation of predatory behaviour in naive great tits (Parus major) towards mimetic complex of four aposematic species of true bugs (Insecta: Hemiptera: Heteroptera): Lygaeus equestris, Spilostethus saxatilis, Pyrrhocoris apterus and Graphosoma lineatum. The birds showed almost no innate wariness against the aposematically coloured bugs, although a hidden wariness elicited by defensive chemicals of some ofthe bug species is not excluded. Naive birds learned to avoid different species at different rates, which resulted in different prey mortalities. The avoidance learning was faster when the defensive chemicals produced an immediate irritating effect (particularly when squirted into distance - G.lineatum) than when they caused sickness several minutes after the consumption (P.apterus). The experience of birds from learning to avoid a particular species of bug affected their subsequent beha
