VogelbalansThe State of the Netherland's Birds 2022

Sovon lists the most important developments in The State of the Netherland’s Birds (Dutch title: Vogelbalans) and outlines which species are increasing, and which are becoming less abundant. Thanks to research and counting efforts by numerous volunteers and professionals, we can determine the trends of 193 species of breeding birds and 172 wintering bird species and explain the reasons behind these changes. In 2023, Sovon celebrates its 50-year anniversary. In this context, this edition of The State of the Netherland’s Birds is all about long time series. Bird populations have been monitored for decades, sometimes in great detail. Over the long term, major shifts become visible that are often caused by human influences.
