Total Length: 35 to 43 cm; Wingspan: 76 to 79 cm (Ref. 8812). A coastal species; <30 km (Ref. 356). This species primarily forage inshore (Ref. 95711). Displays plunge-diving and dipping behavior (Ref. 356). In the North Sea off the east coast of Scotland and northern England, they are known to partially feed on the sandeel, Ammodytes marinus.
