The annual publication “The State of Birds in Switzerland” summarises the results of our various monitoring projects, conducted with the support of more than 2000 volunteers in all parts of the country. The 2019 report focuses on the 20th anniversary of “Monitoring common breeding birds” (Monitoring Häufige Brutvögel, MHB). Thanks to the MHB scheme, the population trends of common and widespread breeding birds have been carefully documented since 1999.
