Seasonal occurrence of six migrating songbird species in the plain of the Aare at Solothurn from 1981 to 2012. – In the plain of the Aare between Büren a.A. (canton of Berne) and Solothurn (canton of Solothurn) all observations of Tree Pipit Anthus trivialis, Meadow Pipit A. pratensis, Water Pipit A. spinoletta, Western Yellow Wagtail Motacilla flava, Whinchat Saxicola rubetra and Northern Wheatear Oenanthe oenanthe were systematically recorded from 1981 to 2012. These six species occur here regularly during autumn and spring migration and yearly in varying numbers. Larger gatherings occur especially when held up by bad weather. The seasonal occurrence is described and shown in phenological diagrams. The migration pattern is compared with other areas in Switzerland. So far the seasonal occurrence of rather common species in Switzerland was roughly described (Glutz von Blotzheim 1962, Winkler 1999) and shown in schematic graphics (Maumary et al. 2007). Phenological diagrams of autumn and spring migration from the same areas on the basis of five-day periods (Berthold 1973) are only available so far for few species and regions, including the area of Lake Constance (Schuster et al. 1983, Heine et al. 1999). On the two Alpine passes Col de Bretolet (canton Valais) and Col de Jaman (canton Vaud) the medians of autumn migration for Tree Pipit (13–14 days), Western Yellow Wagtail (4–7 days), Whinchat (15–17 days) and Northern Wheatear (7–11 days) are markedly earlier than in Solothurn. This could suggest that the four long-distance migrants avoid crossing the Alps with progressing migration and prefer to migrate along the Swiss plateau. With more information on widespread species from daily lists recorded via the online platform ornitho.ch it will be possible to increase the number of species for which phenological diagrams can be compiled.
