Abstract

The Aquatic Warbler Acrocephalus paludicola is a globally threatened European migratory songbird that passes through the Iberian Penninsula during its migration from Western Europe to Africa. The aim of our study was to determine the spatial migratory pattern of the species according to age classes during the post-nuptial passage in the Iberian Peninsula by analysing ringing data. The results confirm the existence of differential migration by age according to a longitudinal geographical gradient and suggest that the more westerly the wetlands, the smaller the proportion of juveniles that use them. Our findings also highlight the existence of a very broad migratory front. These results have implications for the conservation of different areas of migratory passage.

Zusammenfassung

Zeigen Seggenrohrsänger Acrocephalus paludicola im Herbst auf der Iberischen Halbinsel eine altersspezifische Differenzierung des Zugverhaltens?

Der Seggenrohrsänger Acrocephalus paludicola ist eine weltweit bedrohte europäische Singvogelart, die durch Westeuropa und Afrika zieht. Unser Ziel war es, durch die Auswertung von Beringungsdaten das räumliche Zugmuster der Art während des nachbrutzeitlichen Durchzugs auf der Iberischen Halbinsel nach Altersklassen zu beschreiben. Die Ergebnisse bestätigten das Auftreten altersspezifischer Unterschiede im Zugverhalten entlang eines longitudinalen geografischen Gradienten und deuten darauf hin, dass weiter westlich gelegene Feuchtgebiete in geringerem Maße durch Jungvögel genutzt werden. Dies unterstreicht außerdem das Vorhandensein einer sehr breiten Zugfront. Diese Ergebnisse haben Konsequenzen für den Schutz verschiedener Bereiche des Zugweges.
