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.
Murphy's Petrel
39–41 cm. Dark grey-brown above; variable pale grey below with dusky underwing. Breeds widely across central Pacific (Pitcairn, Austral, Henderson islands). Migrates to North Pacific in non-breeding season. Feeds on squid and fish; nocturnal at breeding colonies; Near Threatened.
