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.

37–41 cm. Polymorphic; pale morph grey-brown above with white underparts and dark breast-band; dark morph all sooty. Breeds Trindade Island (Brazil) and Round Island (Mauritius). Ranges in tropical Atlantic and Indian oceans; feeds on squid and flying fish.
