Length at first maturity / Size / Weight / Age
Maturity: Lm ?  range ? - ? cm Max length : 45.0 cm TL male/unsexed; (Ref. 8812); max. published weight: 300.00 g (Ref. 356)
Culmen: 5.8 cm; tarsus: 2.54 cm; wing: 32.5 cm.
Total Length: 40 to 45 cm; Wingspan: 91 to 94 cm (Ref. 8812). A coastal species (Ref. 356), found on beach and shoreline, nearshore and in islands (Ref. 116102). Primarily foraging inshore. In the North Sea off the east coast of Scotland and northern England, they are known to partially feed on the sandeel, Ammodytes marinus. Breeding pairs share incubation and chick-rearing duties in nesting colonies. They surface-feed by scooping prey from the water and carry it in their bills (Ref. 95711). Displays plunge-diving behavior (Ref. 356). Adults feed their chicks with regurgitated food (Ref. 95711).
