Peering into the world of wild passerines with 3D-SOCS: synchronized video capture and posture estimation

The paper introduces 3D-SOCS, a system for collecting behavioral data on wild birds using synchronized video, and finds it can estimate 3D postures and characterize visual fields in great tits.

Fine-scale tracking reveals visual field use for predator detection and escape in collective foraging of pigeon flocks

The paper tracks pigeon flock behavior during predator simulations to show how foveal vision is used for detection and escape, finding earlier foveation correlates with vigilance and faster escape responses.

Gaze tracking of large-billed crows (Corvus macrorhynchos) in a motion-capture system

This study tracks head movements of large-billed crows to infer their visual field use and attentional focus using a motion-capture system.

Testing the effect of oxytocin on social grooming in bonobos

This study tests if oxytocin increases social grooming in bonobos, finding an overall increase but limited individual effects.

Experimental evidence for the gaze-signaling hypothesis: White sclera enhances the visibility of eye gaze direction in humans and chimpanzees

This study shows that white sclera improves eye-gaze detection in humans and chimpanzees, especially under challenging visual conditions.

What is unique about the human eye? Comparative image analysis on the external eye morphology of human and nonhuman great apes

This study compares human and nonhuman great ape eye morphology using image analysis to test if human eye features are uniquely visible for gaze signaling.
