Abstract:

A total of 195 experiments were performed during the fall migration under three basic environmental conditions, in all cases with only the overhead sky visible to the bird. First, under clear starlit skies, secondly, under clear starlit skies with the moon visible, and, finally, tests under artificial overcast. The tests under moonlit skies showed a clear tendency for the bird to head either in the direction of the moon or in the direction of the side of the apparatus lighted by the moon, i.e., directly away from the moon.
