Great tits () flexibly learn that herbivore-induced plant volatiles indicate prey location: An experimental evidence with two tree species.

When searching for food, great tits () can use herbivore-induced plant volatiles (HIPVs) as an indicator of arthropod presence. Their ability to detect HIPVs was shown to be learned, and not innate, yet the flexibility and generalization of learning remain unclear.We studied if, and if so how, naïve and trained great tits () discriminate between herbivore-induced and noninduced saplings of Scotch elm () and cattley guava ().
