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.
Antarctic Prion
25–28 cm, wingspan 58–66 cm. Classic prion pattern: pale blue-grey, white below, bold dark M across upperwing. Medium-broad bill. Most abundant and widespread prion; breeds South Georgia, Heard, Kerguelen, Macquarie. Feeds on crustaceans; makes deep dives compared to congeners.
