Zusammenfassung
In vielen Teilen Skandinaviens sind übereinstimmend in den letzten Jahren Rückgänge im Bestand des Stars festgestellt worden. Die Gründe hierfür sind unbekannt. Vor allem bleibt zu prüfen, ob auch in südlich gelegenen Teilen des Areals Änderungen in der Siedlungsdichte, Reproduktionsrate usw. des Stars festgestellt wurden. Anregungen zu Untersuchungen der Bestandsentwicklung des Stars in Mittel- und Westeuropa bzw. zur Veröffentlichung bisher noch nicht publizierter Befunde werden gegeben.
Summary
After an imitial large-scale increase in all parts of Europe the populations of Starlings have been seriously decreased in Scandinavia, northern parts of the species range.
Data from 8 populations from Finland, 2 from Sweden (Tab.) and notices from Norway show, that population densities have decreased to the level of 0–50% of their previous size. Many reasons have been proposed to be responsible for this: low productivity, pesticides, actions against Starlings in their wintering areas and shortening of suitable breeding habitats, but non of these gives a sufficient explanation.
