Redundancy in use of celestial compass cues

Insects need compass cues in order to perform path integration and the sky provides multiple potential sources of compass information. Polarisation patterns, sun position and chromatic gradients are all informative. Here, Wystrach et al. investigate how Australian desert ants balance the various celestial sources of compass information. They find that ants can flexibly deal with the disruption of individual compass channels and seem to average the directions indicated by conflicting cues.
