(Pat)Terns in space and time: Movement, activity, and habitat preference in breeding Caspian Terns (Hydroprogne caspia)
In this study, Global Positioning System (GPS)-derived tracking data were used to explore aspects of the breeding season movement ecology of an at-risk seabird, the Caspian Tern, in the Baltic Sea. In particular, the foraging effort, daily activity, and foraging habitat use of the terns were investigated at two breeding colonies. Data were collected during two seasons at the colony on Stenarna isl
