Fig.2: Learning walks in Cataglyphis nodus. (Left) Path and time course of an individual learning walk around the nest entrance (black star). Time is color coded, and indicated on the left, the compass (red) is pointing north (N). Firouettes, characteristic body rotations during which the antsstop to look back to the nest entrance indicated by arrows depicting the view direction during the longest stopping phases. Scale bar = 5cm. (Upper right) Mean gaze directions during the longest stopping phases in pirouettesare not significantly different from the nest direction (the inner circle indicates Rayleigh's critical value α = 0.05; further details in FLEISCHMANN & al. 2017). (Lower right) Schematic drawing showing C.nodus performing a pirouette with a nest-directed view during a stopping phase. The green circular arrow shows the center of rotation during a pirouette. The alignments of views during pirouettes were measured and quantified by tracking the tip of the mandibles and the position of the thorax (yellow spots).
