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.
White-necked Petrel
43 cm. Large gadfly petrel; dark above with white hindneck collar; white underparts with dark carpal bar. Breeds Kermadec and Phillip islands (Norfolk). Vulnerable; ranges in southwestern Pacific. Nocturnal at colonies; feeds on squid and fish.
