GMF as a compass cue in honeybees. Honeybees were trained to visit a feeder (F, indicated by the black x) placed in a constant compass direction (e.g., west) from a landmark (black circle) within a tent. During a training (indicated by the question mark on the landmark) and during (b) testing (indicated by the tick on the landmark) when the feeder was removed (indicated by the white x), honeybees faced most often southwards. c When the magnetic field was rotated by 180° (magnetic North (mN) pointing to geographic South), honeybees oriented also southwards relative to the experimental magnetic field. d When the magnets (i.e., the artificial magnetic field) were removed during testing, honeybees oriented themselves relative to the landmarks and ignored the conflicting information provided by the GMF relative to the panorama.
