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.
Vanuatu petrel
37–40 cm. Dark above with white forehead and underparts; black partial collar. Breeds Vanuatu; poorly known. Endangered or Critically Endangered with very few confirmed nests. Described as full species only in 1984; nocturnal at colonies; feeds on squid and fish in tropical Pacific.
