Caspian terns (Hydroprogne caspia) are long-lived migratory seabirds and constitute the largest tern species in the world. We are currently looking for a dedicated master’s students to study the anti-predator behavior, disturbance and nest failure rates during breeding in the largest and oldest Caspian tern colony in Sweden (Stenarna, Björns archipelago, Baltic Sea). The Master’s student will be based in coastal village of Fågelsundet (Uppsala county) between the end of April/early May and mid July 2025 with the fieldwork team and observe Caspian terns in their breeding grounds on Stenarna. The study of anti-predator behavior, mortality and types of disturbances of breeding Caspian terns will occur via a combination of direct observation on the island (with overnight stays in the hide on the Stenarna), by using the surveillance camera that is accessible remotely and tracking data. The student will also have the possibility to partake in chick ringing sessions on Stenarna. Students interested in this project are encouraged to contact Prof Susanne Åkesson for more information and to discuss specific plans for their MSc projects.
