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.
Galapagos Petrel
43 cm. Dark above with white forehead; white underparts with dark collar and carpal bar. Breeds Galapagos Islands; Critically Endangered with rapid decline due to introduced predators. Closely related to Hawaiian Petrel; migrates to eastern Pacific; feeds on squid and fish.
