Proposed Mechanisms for the Navigation of Migrating Birds
The question of how migrating birds find their way when flying at night at great altitudes or in clouds, when no geographical landmarks can be seen, is an old puzzle. The hope of gaining new ideas for the guidance of intercontinental missiles has prompted the armed services to expend considerable research efforts on this quest. The number of papers dealing with this subject is quite impressive, but no final answer has yet been found.1 In the following, two hypotheses are proposed. One of them is a new mechanism, the other a physical phenomenon so far not considered in relation to bird migration.
