Behavioral responses of blackbirds (Turdus merula) and silvereyes (Zosterops lateralis) to the experimental situation and in a natural vineyard setting were compared. The two species behaved in a similar way in the artificial and natural situations, indicating that the experimental method used is a valid and useful tool to investigate bird decision-making mechanisms with natural grapes.Acknowledgment: Funding for the Marlborough Survey was from New Zealand Winegrowers.
