About These Birds
Cape Petrel
38–40 cm, wingspan 81–91 cm. Unmistakable chequered black-and-white plumage with two white wing patches. Abundant in the Southern Ocean; breeds on Antarctic and subantarctic cliff ledges. Follows ships avidly; feeds on krill, fish, and offal. One of the most commonly seen Antarctic seabirds.
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.
