International news

Sound knowledge of the distribution, population sizes and trends of birds in Europe and beyond is indispensable when it comes to evaluating the situation of breeding and visiting birds in Switzerland. We therefore collaborate closely with institutions in other European countries as well as with international organisations in the areas of monitoring and assessment. The Swiss Ornithological Institute is actively involved in several European projects.
