Vol. 35 (2025)

Volume 35 comprises the continuous publishing of open access contributions in Ornis Svecica. The cover (available under the Creative Commons Attribution 4.0 International License) features a young Sandwich Tern Thalasseus sandvicensis, photographed in July 2016 at Närsholmen, Gotland, Sweden, by Niclas Ahlberg/N © (niclasahlberg.se). This is the focal species of this year’s first paper, in which Olofsson et al. (2025) analyze the population development of the species as a Swedish breeding bird.
