About These Birds
흰머리수리
흰머리독수리는 미국의 국조이자 국가 상징입니다. DDT 살충제 사용으로 인해 한때 멸종위기에 처했으나 놀라운 회복을 보여 2007년 멸종위기종 목록에서 제외되었습니다. 이 강력한 맹금류는 어떤 새보다 가장 큰 나무 둥지를 만들며, 어떤 것들은 2톤 이상이 됩니다.
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.
