Juvenile Songbirds Compensate for Displacement to Oceanic Islands during Autumn Migration
To what degree juvenile migrant birds are able to correct for orientation errors or wind drift is still largely unknown. We studied the orientation of passerines on the Faroe Islands far off the normal migration routes of European migrants. The ability to compensate for displacement was tested in na...
