However, exclusion may be based on avoidance of the empty location without drawing inferences about the presence of the food in the baited location. So far, such inferences have been demonstrated in the great apes only: after seeing an experimenter eating one of two food types, which both had been hidden previously in two boxes, the apes were able to choose the box that still contained the other food type. African grey parrots are capable of exclusion, and we here assessed if they are capable of inference by exclusion. In our task, two different but equally preferred food items were hidden in full view of the birds under two opaque cups. Then, an experimenter secretly removed one food type and showed it to the bird. Similarly to the apes, one out of seven parrots significantly preferred the baited cup; control conditions rule out that its choice was based on associative learning or the use of olfactory cues. Thus, we conclude that—like the apes—some grey parrots are able to infer the location of a hidden food reward."],["dc.identifier.doi","10.1098/rsbl.2011.0500"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/116123"],["dc.language.iso","en"],["dc.notes.intern","DOI-Import GROB-602"],["dc.relation.eissn","1744-957X"],["dc.relation.issn","1744-9561"],["dc.relation.orgunit","Deutsches Primatenzentrum"],["dc.rights.uri","https://royalsociety.org/journals/ethics-policies/data-sharing-mining/"],["dc.title","African grey parrots (\n Psittacus erithacus\n ) use inference by exclusion to find hidden food"],["dc.type","journal_article"],["dc.type.internalPublication","unknown"],["dspace.entity.type","Publication"]]

While the ravens chose by exclusion, the jackdaws did not. Thus, foraging behaviour may affect EP abilities. To investigate this possibility, another food-caching corvid species, the carrion crow (Corvus corone corone), was tested in the same exclusion task. We hid food under one of two cups and subsequently lifted either both cups, or the baited or the un-baited cup. The crows were significantly above chance when both cups were lifted or when only the baited cup was lifted. When the empty cup was lifted, we found considerable inter-individual variation, with some birds having a significant preference for the un-baited but manipulated cup. In a follow-up task, we always provided the birds with the full information about the food location, but manipulated in which order they saw the hiding or the removal of food. Interestingly, they strongly preferred the cup which was manipulated last, even if it did not contain any food. Therefore, we repeated the first experiment but controlled for the movement of the cups. In this case, more crows found the food reliably in the un-baited condition. We conclude that carrion crows are able to choose by exclusion, but local enhancement has a strong influence on their performance and may overshadow potential inferential abilities. However, these findings support the hypothesis that caching might be a key to exclusion in corvids."],["dc.identifier.doi","10.1007/s10071-011-0434-1"],["dc.identifier.purl","https://resolver.sub.uni-goettingen.de/purl?gs-1/8832"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/60620"],["dc.language.iso","en"],["dc.notes.intern","Merged from goescholar"],["dc.publisher","Springer"],["dc.publisher.place","Berlin/Heidelberg"],["dc.rights","Goescholar"],["dc.rights.uri","https://goescholar.uni-goettingen.de/licenses"],["dc.title","Is caching the key to exclusion in corvids?
