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.
Barolo Shearwater
25–28 cm. Small; dark above, white below with white cheeks. Breeds Macaronesian islands (Canaries, Azores). Ranges in North Atlantic. Near Threatened; threatened by introduced predators and light pollution. Formerly lumped with Little Shearwater; fast direct flight.
