ABSTRACT
In every species that has cognition, individual organisms take account of the orientations of things (see Fraenkel & Gunn, 1940). Ants leave their nests and search great distances for food or for other ant colonies. How does an ant find its way back? appears that ants see stripes in the sky, due to their sensitivity to the polarization of sunlight. As an ant forages, its average heading is encoded as an angle relative to the stripes in the sky (e.g., Schone, 1984). To return home, the ant reverses direction.
