Seasonal occurrence of Winter Wren Troglodytes troglodytes, Dunnock Prunella modularis and European Robin Erithacus rubecula in a small wetland in Switzerland. – Winter Wrens, Dunnocks and European Robins were recorded weekly by thirty-minute surveys in a small wetland (total area 5 ha) in the Aare plain near Solothurn (Switzerland) from 1983 to 2007. The wetland is used by the three species only during migration and in winter. It is therefore well adapted to show the seasonal occurrence of these forest birds. Autumn migration is significantly more intensive than spring migration in all three species. In Wren and Dunnock, the migration peak in autumn is reached later than in the Alps, in the Jura mountains or at Lake Constance. In winters with many snow and ice days numbers of all three species are smaller than in mild winters.
