Every 20 years, the Swiss Ornithological Institute and its more than 2000 volunteer collaborators survey the distribution and population sizes of our native breeding birds as comprehensively as possible. The results of the surveys carried out from 2013 to 2016 are presented in the new breeding bird atlas*. For the first time, we are able to represent quantitative changes in the form of density and distribution change maps, thanks to cutting-edge analytical techniques and a methodology similar to the one used for the 1993–1996 atlas. The maps show the changes, some of them dramatic, that have occurred in a relatively short period of time. Farmland birds in particular have seen steep declines, while the populations of generalist species have increased. This year’s edition of The State of Birds in Switzerland presents the most important results of the breeding bird atlas in a special issue. Please note: The atlas is available in print in German, French and Italian. An English version will be accessible online from January 2019.
