Role of different colours of aposematic insects in learning, memory and generalization of naive bird predators
Original language description
The role of the red-coloured wild-type and some coloured mutants (white, yellow and orange) of an aposematic insect (firebug, Pyrrhocoris apterus) was tested in unlearned avoidance, learning, memory and generalization of a naive avian predator (great tit, Parus major). Wild-caught great tits avoid the firebug depending on colour, and their reaction to variously coloured prey is a result of avoidance learning and may vary according to their experience. Naive, hand-reared great tits showed no initial avoidance and attacked firebugs irrespective of colour. The results od the study showed that red colour represents a more effective signal than the yellow. The naive tits learned to avoid all the colour form at a similar rate, but generalization their experience was asymmetric.
