Abstract

We examined migration routes and non-breeding sites of a poorly studied long-distance migrant, the Semi-collared Flycatcher Ficedula semitorquata, by tracking adult birds with geolocators from an eastern European breeding population across two subsequent years. All 11 birds migrated in a clockwise loop fashion where autumn migration routes lay east from the spring migration routes. Non-breeding sites were located in Eastern-Central Africa, i.e. Uganda, Tanzania, Burundi, Rwanda, and east DR Congo, where birds spent on average 128 days. Non-breeding sites of two birds were located outside of the currently estimated species’ non-breeding range.

Zusammenfassung

Räumlich-zeitliche Verbreitung des wenig bekannten HalbringschnäppersFicedula semitorquataim Jahresgang

Wir bestimmten Zugwege und Überwinterungsgebiete eines wenig bekannten Langstreckenziehers, des Halbringschnäppers Ficedula semitorquata. Mit Hilfe von Geolokatoren verfolgten wir adulte Vögel einer osteuropäischen Population während zweier aufeinanderfolgender Jahre. Alle 11 Halbringschnäpper zogen schleifenförmig im Uhrzeigersinn mit einer östlicheren Herbstzugroute und einer mehr westlichen Frühlingszugroute. Die Überwinterungsgebiete lagen im östlichen Zentralafrika (östlicher Teil der Republik Kongo) und Ostafrika (Uganda, Tansania, Burundi, Ruanda). Die Vögel verbrachten durchschnittlich 128 Tage im Überwinterungsgebiet. Zwei Vögel überwinterten ausserhalb des bisher angenommen Verbreitungsgebietes der Art.
