Large black and white seabird, breeding in large colonies on cliffs and offshore islands of Norway, the British Isles, Ireland, Iceland and Faroe, France, and E. Canada. Wanders the Atlantic Ocean outside breeding season south to W Africa, feeding on fish caught by characteristic plunge-dives. Young birds migrate to south of its range, adults range less far. Ring recoveries suggest shorter migrations than geolocator tracking, but indicate no long-term change in migration distances (Laurenson et al. 2021). European population 683,000 breeding pairs, increasing. Frequently drowns in fishing nets.
