About These Birds
Blue Petrel
파란페트렐(26–32cm, 날개 길이 60–71cm)은 특유의 흰 끝 사각형 꼬리를 지닌 청회색 바닷새로 아랫면은 흰색이다. 아남극 섬에서 번식하고 남극해를 광범위하게 유랑한다.
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.
