    While biodiversity measures have led to increases in some farmland species in 2021, others continue to suffer losses due to intensive agriculture.

     

    Birds that favour open habitats, wetlands, hedges or low-intensity farmland occur in above-average numbers on military training sites.

     

    The southern end of Lake Neuchâtel accommodates many species in nationally important numbers. The Association de la Grande Cariçaie manages the area and is in charge of population monitoring.

     

    «Monitoring common breeding birds» (MHB) brings to light the large-scale decline of the European Greenfinch. The nosedive can be traced to a parasite infecting the birds’ digestive tract.

     

    The Red-rumped Swallow extends its range in Europe to the north. It has been observed in Switzerland almost every year since 2000. Spring 2021 saw the greatest influx so far.

     

    In January 2022, 430 000 waterbirds were recorded in Switzerland, the lowest count since about 1970. The wintering numbers of common species such as Tufted Duck, Common Pochard and Mallard are in decline.

     

    Compared to other countries in central Europe, the positive trends of woodland birds in Switzerland since 1990 stand out. However, many farmland species in our country suffered their greatest losses before 1990.
