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.
Atlantic Petrel
43 cm, wingspan 104 cm. Large; dark brown above with pale belly and dusky breast-band creating hooded appearance. Breeds Tristan da Cunha and Gough Island; ranges into south Atlantic and Indian Ocean. Endangered; threatened by introduced predators and longline fisheries.
