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.
Subantarctic Shearwater
27–30 cm. Dark above; white below with clean sharp borders; slightly larger than related small shearwaters. Breeds subantarctic islands (Tristan da Cunha, Gough, St. Paul). Ranges in subantarctic Southern Ocean. Separated from Little Shearwater by range and subtle differences.
