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.
Soft-plumaged Petrel
32–37 cm, wingspan 83–95 cm. Grey above; white below with a distinctive dark partial breast-band and dark-streaked face. Breeds Tristan, Gough, and southern Indian Ocean islands. Ranges widely in Southern Ocean. Feeds on fish and squid; arcs steeply in strong winds.
