Layout of the aviaries. Group aviaries are depicted on the left, the separation aviary on the right. Presentations were conducted either for both complete groups, or for a single separated raven. The presenter walked along the horizontal line, following the direction indicated by the arrows, and stopped at two locations per aviary (indicated by numbered circles), where they faced the ravens while remaining still for two minutes. The vertical bar represents a visual, but not acoustic barrier between the group and separation aviaries
