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.
Red-crowned Crane
The red-crowned crane is one of the rarest crane species and a potent symbol of longevity and fidelity in East Asian culture. Their elaborate unison call and dancing displays have inspired art and folklore for millennia. The resident population on Hokkaido, Japan, recovered from about 33 birds in 1952 to over 1,800 today.
