Early in his research, Kramer found that caged migratory birds became very
restless at about the time they would normally have begun migration in the wild.
Furthermore, he noticed that as they fluttered around in the cage, they often
launched themselves in the direction of their normal migratory route. He then set
up experiments with caged starlings and found that their orientation was, in fact,
in the proper migratory direction except when the sky was overcast, at which
times there was no clear direction to their restless movements. Kramer surmised,
therefore, that they were orienting according to the position of the Sun. To test
this idea, he blocked their view of the Sun and used mirrors to change its apparent
position. He found that under these circumstances, the birds oriented with respect
to the new "Sun." They seemed to be using the Sun as a compass to determine
direction. At the time, this idea seemed preposterous . How could a bird navigate
by the Sun when some of us lose our way with road maps? Obviously, more testing
was in order.
