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.

Black-winged Petrel

30 cm. Small gadfly petrel; pale grey above with dark M-mark; white below with dark carpal patch and partial collar. Breeds Lord Howe, Kermadec, and central Pacific islands. Migrates to North Pacific; feeds on small squid and fish.
