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.
뱀잡이수리
The secretary bird is the only raptor that hunts primarily on foot, striding through grasslands on crane-like legs up to 1.2 meters tall. Its name may derive from the crest feathers resembling quill pens tucked behind a secretary's ear. The species is classified as Endangered due to habitat loss and decline across much of its range.
