Additional file 1. Additional methods. Additional results and discussion. (1) Study site: nest locations, movements between years and age of first breeding. Table S1. Nest locations of pairs that remained together in 2017 and 2018. Table S2. Nest locations of pair members that changed between years. Figure S1. Plan of courtyard study area and age of first breeding. (2) Productivity estimates. (3) Body mass changes and clutch sizes of geolocator-tagged pairs. Table S3. Clutch sizes and capture/re-capture mass of pairs in 2018. (4) Size-corrected body mass of chicks from nests of geolocator-tagged birds. Figure S2. Log (Body mass) plotted against log (Head length) for Arctic Tern chicks. (5) Geolocators and overall breeding performance. (6) Longitude trajectories in the non-breeding area. Figure S3. Longitude trajectories of pairs in 24-h daylight and in the interval between the end of 24-h daylight and departure from the Antarctic ice zone.
