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.
Kermadec Petrel
38 cm. Polymorphic: pale morph has white underparts; dark morph is all brown-grey. Breeds Kermadec, Juan Fernandez, and Pacific islands. Ranges widely in subtropical and tropical Pacific. Feeds on fish and squid; nests in rock crevices and burrows.
