State of Birds 2021

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 2021 report focuses on the publication of the second European Breeding Bird Atlas (EBBA2) and its implications for Switzerland. It also takes a closer look at trends in scarce breeding birds like Western Yellow Wagtail, rare passage migrants such as Glossy Ibis, and local winter visitors such as Whooper Swan.
