Abstract
First breeding record of the Common Tern Sterna hirundo at Lake Sempach, Central Switzerland. The first breeding record of Common Terns at Lake Sempach was recorded in summer 2022. A breeding pair successfully raised three young on the rooftop of the
Swiss Ornithological Instituteʼs visitor centre on the south-eastern shore of the lake. The chicks hatched in mid-June and fledged on 7/8 July. The adult birds were
attracted by 7 self-made decoy terns that I had placed on the gravelly flat roof for the first time two years earlier. In 2023, again, a breeding pair raised three fledglings at this site. This new settlement, 34 km from the next breeding site, may have been favoured by a strong increase in the breeding population of the Common Tern in Switzerland, by the newly available gravel roof and the abundance of fish in Lake Sempach.
