About These Birds
European Roller
파랑새롤러는 비행 중 구르고 굴러다니는 화려한 공중 묘기에서 이름을 얻었다. 수컷은 번식기에 이 공중 묘기로 암컷을 유혹한다. 밝은 파란색과 밤색이 눈에 띈다.
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.
