About These Birds
Northern Giant Petrel
80–95 cm, wingspan 150–200 cm. Resembles Southern Giant Petrel but bill tip is reddish-brown; lacks white morph. Breeds subantarctic islands (South Georgia, Macquarie, Auckland). Ranges north into subtropics; scavenges offal and carrion at sea. Near Threatened due to longline bycatch.
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.
