State of Birds 2023

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 2023 report focuses on environmental factors that affect our bird communities, such as extreme weather events and climate change. It also explores trends in species whose populations have increased in Switzerland or Europe in recent years.
