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.
Peregrine Falcon
世界最速の動物として知られるハヤブサで、急降下時には時速320キロメートルを超えることがある。南極を除く全大陸に生息し、都市部での繁殖も増加している。
