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.
Providence Petrel
40 cm, wingspan 96–100 cm. Dark brown overall with pale forehead; underwing shows white flash at base of primaries. Breeds Lord Howe Island; migrates to North Pacific after breeding. Feeds on squid and fish; populations recovering after predator control on Lord Howe.
