Biology     Glossary (e.g. epibenthic)

In the North Sea off the east coast of Scotland and northern England, this species primarily forage inshore and breeding birds only spend approx. 30% of daylight period at sea, feeding primarily on the sandeel, Ammodytes marinus. They surface-feed by scooping prey from the water and also able to exploit the water column by diving. They form nesting colonies with breeding pairs sharing incubation and chick-rearing duties. Adults feed their chicks with regurgitated food (Ref. 95711).
