About These Birds

Small Saint Helena Petrel

Extinct; known only from subfossil bones from St. Helena Island. Smaller than Bulwer's Petrel; went extinct shortly after human settlement of St. Helena, likely from introduced predators. Part of the endemic St. Helena seabird community that was largely extirpated by human arrival.

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.
