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.
South Georgia Diving-petrel
20 cm. Tiny; dark above, white below; paler scapular edges. Breeds South Georgia, Kerguelen, and Heard Island. Extremely abundant; possibly billions of individuals in Southern Ocean. Feeds on euphausiids by diving; sympatric with Common Diving-petrel but smaller with narrower bill.
