Vasopressin 1a receptor antagonist disrupts male-male affiliative relationships formed by triadic cohabitation in large-billed crows

This study shows that blocking the vasopressin 1a receptor disrupts affiliative relationships in triadic male crow cohabitation, suggesting a role for the VP system in maintaining same-sex affiliations.

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.

Interceptive capturing in large-billed crows: Velocity-dependent weighing of prediction of future target location and visual feedback of current target location.

This study shows that large-billed crows adjust their interception strategy based on target velocity, using predictive mechanisms for fast targets and visual feedback for slow targets.

Rapid adjustment of pecking trajectory to prism-induced visual shifts in crows.

This study compares how pigeons and crows adjust their pecking trajectories to visual shifts caused by prisms, finding that crows show more flexible visuomotor control.
