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.
Little Shearwater
25–30 cm. Small shearwater; dark above with white underparts and extensive white on face and sides of neck. Breeds Canary Islands, Madeira, and southern hemisphere islands; ranges in adjacent oceans. Feeds on small fish and squid; fast fluttering flight close to water.
