About These Birds
Southern Fulmar
45–50 cm, wingspan 115–120 cm. Pale grey above, white below with dark wingtips; pink bill with blue tube-nose. Breeds Antarctic cliffs; ranges across Southern Ocean to about 35°S after breeding. Feeds on fish, squid, and krill by surface-seizing. Highly colonial; migratory.
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.
