About These Birds
Northern Fulmar
The northern fulmar is a long-lived seabird that can survive over 40 years. It defends its nest by projectile-vomiting a foul-smelling stomach oil at intruders, which can mat the feathers of predators and cause fatal loss of waterproofing. Fulmars have expanded their breeding range dramatically southward over the past two centuries.
Manx Shearwater
30–38 cm, wingspan 76–89 cm. Classic small shearwater; jet-black above, brilliant white below; rapid wing-beats and stiff glides. Breeds UK, Faroe, Iceland, and Canary islands; makes extraordinary migrations to south Atlantic. Feeds on fish and squid; nocturnal at colonies. Near Threatened.
