Abstract
This study examined contrafreeloading—choosing a physical task to access food over free food—in two Grey parrots (Psittacus erithacus). Both birds contrafreeloaded for food of equal or higher value, but differed in which contrafreeloading task they preferred. Differences between the parrots are considered as individual preferences for self-reinforcing tasks.
