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.
Common Diving-petrel
20–25 cm. Dark above; white below; broad wings used for underwater propulsion. Most widespread diving-petrel; breeds New Zealand, southern Australia, Falklands, and subantarctic islands. Feeds on small fish and crustaceans by diving. Highly vulnerable to introduced predators at nesting colonies.
