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.
Salvin's Prion
25–28 cm, wingspan 57–63 cm. Similar to Broad-billed Prion but bill intermediate in width; blue-grey above with dark W-wing mark. Breeds Crozet and Marion islands in Indian Ocean. Feeds on crustaceans by filter-seizing at surface. Distinguished from congeners mainly by bill width.
