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.
Large Saint Helena Petrel
Extinct; known only from subfossil bones found on St. Helena. Medium-large petrel that went extinct within the last few centuries, likely due to human settlement, habitat destruction, and introduced predators. Related to living Pterodroma species; part of the endemic St. Helena avifauna.
