The magnetic field as a reference system for genetically encoded migratory direction in pied flycatchers ficedula hypoleuca

Beck W.; Wiltschko W.

To see whether the migratory orientation of pied flycatchers (F. hypoleuca Pallas) is genetically encoded with respect to the earth magnetic field, a group of young birds was hand-raised. They were thus prevented from ever experiencing the sky. The birds were tested in autumn 1980 and 1981 in the local geomagnetic field and in 3 artificial fields. Their magnetic compass matures independent of any experience with the sky and contains sufficient information for the birds to orient toward their migratory direction.
