Total Length: 40 to 45 cm; Wingspan: 63 to 66 cm (Ref. 8812). Found along coasts; <15 km (Ref. 356). In the North Sea off the east coast of Scotland and northern England, this species primarily forage inshore and feed on the sandeel, Ammodytes marinus (Ref. 95711). Known to be pursuit divers (Ref. 356). They surface-feed by scooping prey from the water and also able to exploit the water column by diving; carrying prey in their bills back to their colony. In nesting colonies, breeding pairs share incubation and chick-rearing duties. Adults feed their chicks with regurgitated food (Ref. 95711).
