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.
No Room For Speciesism In Welfare Considerations, Jennifer Vonk
No Room For Speciesism In Welfare Considerations, Jennifer Vonk
Animal Sentience
Speciesism should play no role in determining welfare outcomes. Cognition may vary within species as well as between species, but broad classifications such as invertebrates are functionally meaningless in this context. Cognition should relate to welfare only to the extent that it relates to the capacity to suffer or to experience pleasure.

Animal Sentience
Mikhalevich & Powell (2020) have built on the discussion about which species deserve inclusion in animal ethics and welfare considerations. Here, we raise questions concerning the assessment criteria. We ask how to assess different species for their ability to fulfill the criteria, which criteria are most important, how we quantify them (absolute or on a continuum), and how non-animals such as fungi and plants fit into this paradigm.
