Fig. 3. Intersection points of homeward runs of different individuals of
Cataglyphis fortis, at 1 m and 2 m radius from the release point.
Long arrows depict vector strengths at the 2 m radius, where full radial
length equals 1. Short arrows show the true vector to the nest in 3D tests and
ground distance controls (black), walking distance controls (white), and
straight controls (grey). (A) 3D outbound run (N=26 at 1 m,
N=23 at 2 m radius); (B) ground distance control (N=22 at 1
m, N=20 at 2 m radius); (C) walking distance control (N=21,
both radii); (D) straight control (N=20, both radii). Note that data
points obscure others with identical azimuth.
