Presence And Degree Of Contrafreeloading In African Grey Parrots (Psittacus Erithacus), Gabriella E. Smith

Theses and Dissertations

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.

Using Object-Choice Tasks To Investigate Sensory Perception In Sunda Pangolins (Manis Javanica), Joshua Dipaola

In this study, we used an object-choice task to assess the ecological relevance and use of sensory information in Sunda pangolin foraging behavior. This is the first controlled experiment on pangolin behavior to our knowledge.
