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 Petrel
40–46 cm, wingspan 100–110 cm. Striking chocolate-brown and white pattern; only member of its genus. Breeds solely in Antarctica on cliff ledges; among the most southerly-nesting birds. Feeds on fish and krill beneath pack ice. Returns to colonies in October; one of the most abundant Antarctic seabirds.
