The quality of social relationships in ravens
Open accessAbstract
The quality of a social relationship represents the history of past social interactions between two individuals, from which the nature and outcome of future interactions can be predicted. Current theory predicts that relationship quality comprises three separate components, its value, compatibility and security. This study is the first to investigate the components of relationship quality in a large-brained bird. Following methods recently used to obtain quantitative measures of each relationship quality component in chimpanzees, Pan troglodytes, we entered data on seven behavioural variables from a group of 11 ravens, Corvus corax, into a principal components analysis. The characteristics of the extracted components matched those predicted for value, compatibility and security, and were labelled as such. When the effects of kinship and sex combination on each relationship quality component were analysed, we found that kin had more valuable relationships, whereas females had less secure and compatible relationships, although the effect of sex combination on compatibility only applied to nonkin. These patterns are consistent with what little knowledge we have of raven relationships from aviary studies and show that the components of relationship quality in ravens may indeed be analogous to those in chimpanzees.

Social bonds in birds reflect a lifetime of interactions for evaluating mate choice, and for establishing relationships and parental behavior.
“Social bonds in birds reflect a lifetime of interactions for evaluating mate choice (Dubois et al., 1998), and for establishing relationships and parental behavior (Fraser and Bugnyar, 2010).”
From Husbandry and enclosure influences on penguin behavior and conservation breeding (2016) · cites this paper as Fraser and Bugnyar, 2010
The Discussion (page unavailable) describes raven pair bonds as long-term investments tied to consistent interactions over time, supporting the relationship portion of the claim. Our copy does not link those bonds to parental behavior, and its findings concern primarily young, aviary-housed ravens rather than birds generally. The mate-choice clause is attributed to a different citation and is not assessed here. (LLM, conf=0.83)

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
