About These Birds
Small Saint Helena Petrel
멸종; 세인트헬레나 섬의 아화석 뼈로만 알려져 있습니다. 뻘어즈슴새보다 작으며, 섬에 인간이 정착한 직후 도입된 포식자로 인해 멸종했을 가능성이 높습니다. 인간 도착으로 대부분 멸종된 세인트헬레나 고유 바닷새 군집의 일원입니다.
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.
