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.
Snow Petrel
30–35 cm, wingspan 75–95 cm. Entirely snow-white plumage; black bill, eyes, and feet. Nests in rock crevices deep in Antarctica, among the southernmost breeding birds on Earth. Feeds on krill and fish under pack ice. Highly territorial at nest; secretes stomach oil as defence.
