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.
MacGillivray's Prion
25–27 cm. Medium-billed prion intermediate between Broad-billed and Fairy prions; pale blue-grey with dark M-mark. Breeds St. Paul and Amsterdam islands in southern Indian Ocean. Very restricted range; feeds on zooplankton and small crustaceans at sea surface.
