Two chapters in this thesis try to explain whether insectivorous birds can smell volatile compounds released by plants attacked by herbivorous insect, and use them as a cue to locate prey rich plants. First chapter describes field experiments with chemical induction of volatile compounds similar to those released during real herbivory. Second chapter depicts foraging behaviour of birds towards trees with "true" herbivory caused by live caterpillars in a cage experiment.
