Can we trace the social affiliation of rooks (Corvusfrugilegus) through their vocal signature?

This study investigates whether rooks use vocal signatures to indicate social affiliations at different levels, finding only individual-level signatures.

Social influences on delayed gratification in New Caledonian crows and Eurasian jays

This study examines how social context affects delayed gratification in New Caledonian crows and Eurasian jays, finding species differences in reward selection under varying social conditions.

Individual repeatability, species differences, and the influence of socio-ecological factors on neophobia in 10 corvid species

This study investigates neophobia in 10 corvid species, finding species differences and socio-ecological influences on novelty responses across 241 subjects in 10 labs.

Little evidence that Eurasian jays (Garrulus glandarius) protect their caches by responding to cues about a conspecific's desire and visual perspective

This study tests whether Eurasian jays adjust caching behavior based on conspecifics' visual perspective or desire, finding little evidence for such responses.

Testing two competing hypotheses for Eurasian jays' caching for the future: planning versus compensatory caching

The paper tests two hypotheses for corvid caching behavior and finds neither explains the observed caching pattern, suggesting a need for further research.

How flexible is tool use in Eurasian jays (Garrulus glandarius)?

This study investigates tool use in Eurasian jays, finding limited tool selectivity but ability to use different tools for similar tasks.

Decision-making flexibility in New Caledonian crows, young children and adult humans in a multi-dimensional tool-use task

This study compares decision-making flexibility in New Caledonian crows, children, and humans during a tool-use task, finding differences in tool selection and adaptability to complexity.
