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.
Fluttering Shearwater
33 cm. Dark brown above; white below; relatively short-tailed. Breeds New Zealand North Island coast; non-breeding range restricted to Tasman Sea and nearby waters. Sedentary compared to most shearwaters; feeds on fish and squid. Near Threatened due to small range.
