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.
Broad-billed Prion
25–30 cm, wingspan 57–66 cm. Largest prion; pale blue-grey above, white below with dark M-mark across wings. Bill broad, blue with lamellae for filter-feeding on copepods. Breeds Tristan da Cunha and New Zealand subantarctic. Feeds by hydroplaning with bill submerged.
