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.
Fiji Petrel
30 cm. Small dark petrel; all dark brown with slightly paler chin. Critically Endangered; only one confirmed breeding record from Gau Island, Fiji. Fewer than 50 known sightings total. Possibly nests in highland forest burrows; one of the rarest and least-known petrels.
