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.
Hutton's Shearwater
38 cm. Dark above; white below; larger than Fluttering Shearwater. Breeds only in alpine zone of Kaikoura Ranges, South Island, New Zealand. Endangered; very restricted inland breeding range unique among shearwaters; feeds at sea in Tasman Sea and off south Australia.
