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.
Great-winged Petrel
41 cm, wingspan 97 cm. Large all-dark gadfly petrel; dusky bill, black feet. Breeds on islands from Tristan da Cunha to SW Australia and New Zealand. Ranges widely in southern Atlantic, Indian, and Pacific oceans. Flies with characteristic high arcing; feeds on squid and fish.
