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.
Peruvian Diving-petrel
22–24 cm. Small, stocky diving seabird; dark above, white below. Breeds coastal Peru and Chile; non-migratory. Uses wings to 'fly' underwater like alcids; feeds on anchovy and krill in the Humboldt Current. Endangered; highly vulnerable to El Niño events and guano harvesting disturbance.
