Abstract

Quails were tested for leftward and rightward turning preferences in a detour task. When facing a mirror located behind a barrier composed of vertical bars, quails showed a striking population-level preference for turning leftward. In order to check whether the asymmetry reflected a motor or a sensory (i.e. visual hemifield) bias, in a second experiment quails were reared in pairs and then tested in the detour task with a familiar (companion) or an unfamiliar (stranger) conspecific as a target. Quails turned leftward when viewing the stranger, but they turned rightward when viewing the companion. These findings are dis- cussed in relation to current evidence for brain lateralization in response to social stimuli in non-human animals.[...]
