About These Birds
Southern Giant Petrel
86–99 cm, wingspan 185–205 cm; largest procellariid. Bill massive, pale horn with greenish tip. Two morphs: brown-and-white and rare all-white. Breeds Antarctic and subantarctic islands; ranges widely in Southern Ocean. Scavenges carrion and kills penguins; dominant at seal carcasses.
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.
