Morphologie
Culmen: 4.56 cm; tarsus: 2.88 cm; wing: 17.21 cm.
Total Length: 28 to 30 cm; Wingspan: 53 to 58 cm (Ref. 8812). Occupy the continental shelf; <100 km; exhibits plunge-diving feeding behavior (Ref. 356). In the North Sea off the east coast of Scotland and northern England, this species is known to feed on the sandeel, Ammodytes marinus and breeding birds spend approx. 80% of daylight period at sea, commonly in dense rafts. They form nesting colonies with breeding pairs sharing incubation and chick-rearing duties; surface-feeding by scooping prey from the water, they carry prey in their bills and feed their chicks with regurgitated food (Ref. 95711).
