.... (B) Magnetic and celestial compass orientation of first-year Eurasian reed warblers tested under the different experimental treatments (magnet, magnet+celestial cues) of experiment 2 during autumn migration. Circular diagrams depict the birds’ individual mean directions from repeated orientation...

... by The Company of Biologists Ltd 2017 http://www.biologists.com/user-licence-1-1/ Summary: Different Cataglyphis desert ant species include distinct types of turn, namely voltes and pirouettes, in their learning walks that may serve different navigational purposes. Celestial compass Central...

..., use just two analyzer channels. Although this excludes the perception of specific e-vector orientations, a two-channel system does provide a coarse, categoric analysis of polarized light stimuli, comparable to the limited color sense of dichromatic, ‘color-blind’ humans. The celestial compass...

... demonstrate navigational functions of the ocelli in the visually guided Australian desert ant Melophorus bagoti . These ants are known to rely on both visual landmark learning and path integration. We conducted experiments to reveal the role of ocelli in the perception and use of celestial compass information...

.... In this study we manipulate the amount of celestial compass information available to the bee during flight, and analyse the encoding of spatial information in the waggle dance as well as in the navigation of the foraging bee. We find that the waggle dance encodes information about the total distance flown...

... the calibration reference for the magnetic compass. In contrast, during migration, a majority of experiments suggest that birds rely on the magnetic field as the primary source of compass information and use it to calibrate celestial compass cues, i.e. the relative saliency of magnetic and celestial cues...
