Analysis of foraging success of adult and juvenile Starlings in June, July and August indicates that juveniles are less successful than adults at catching their animal food, especially leatherjackets. I suggest that this low success in gathering animal food effectively causes a shortage that drives young Starlings to eat easily accessible cherries.
