| Abstract: | Summary In experiments performed in Italy, altered magnetic fields were effective in biasing the initial orientation of Italian pigeons but not that of German pigeons raised in Italy, suggesting a genetic difference between the two bird stocks.We are grateful to Dr H. G. Wallraff who kindly supplied the German pigeons used in our experiments and gave useful suggestions. |
