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.
Jamaican Petrel
36 cm. Dark sooty-brown throughout with slightly paler underparts. Possibly Critically Endangered or extinct; last confirmed sighting 1879 in Jamaica. Likely nested in Blue Mountains. If surviving, threatened by mongoose predation and habitat loss; only occasional sight records at sea.
