Fulmarus glacialis
The Fulmar is a medium-sized seabird that can be seen in Britain, particularly in coastal areas, throughout the year, with large colonies found on rocky outcrops and islands. It is a common sight in British waters, especially during the breeding season, when it can be spotted on cliffs and rocky coastlines.
Use these features to identify Fulmar in the field.
The Fulmar can be identified by its grey and white plumage, with a distinctive white rump patch and a thick, black bill, as well as its broad, rounded wings and a distinctive tube-shaped nostril on its upper mandible.
The Fulmar is slightly larger than a Herring Gull, but smaller than a Lesser Black-backed Gull.
The male Fulmar has a grey back and wings, with a white belly and rump, and a black stripe above its eye, with no significant seasonal variation in its plumage.
The female Fulmar is similar to the male, with no notable differences in plumage.
The Fulmar's call is a loud, guttural "ka-ka-ka" or "cack-cack-cack" sound, often heard during the breeding season.
Fulmars are skilled gliders, using rising air currents to stay aloft, and they feed on fish, crustaceans, and carrion, often following fishing boats to scavenge for food.
The Fulmar can be confused with the Gannet, but can be distinguished by its thicker bill, more rounded wings, and greyer plumage, as well as its distinctive tube-shaped nostril.
