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 naturally occurring vagrants presumably displaced by wind and in birds experimentally displaced 1100 km from Denmark to the Faroes. The orientation was studied in orientation cages as well as in the free-flying birds after release by tracking departures using small radio transmitters. Both the naturally displaced and the experimentally displaced birds oriented in more easterly directions on the Faroes than was observed in Denmark prior to displacement. This pattern was even more pronounced in departure directions, perhaps because of wind influence. The clear directional compensation found even in experimentally displaced birds indicates that first-year birds can also possess the ability to correct for displacement in some circumstances, possibly involving either some primitive form of true navigation, or ‘sign posts’, but the cues used for this are highly speculative. We also found some indications of differences between species in the reaction to displacement. Such differences might be involved in the diversity of results reported in displacement studies so far.</dcterms:abstract> <dcterms:bibliographicCitation>Publ. in: PLoS one ; 6 (2011), 3. - e17903</dcterms:bibliographicCitation> <dc:creator>Holland, Richard A.</dc:creator> <dc:creator>Thorup, Kasper</dc:creator> <dc:contributor>Thorup, Kasper</dc:contributor> <dc:creator>Rabøl, Jørgen</dc:creator> <dcterms:issued>2011</dcterms:issued> </rdf:Description> </rdf:RDF>
