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.
Roseate Spoonbill
The roseate spoonbill is the only spoonbill species in the Americas and one of the most striking wading birds in the Western Hemisphere. Like flamingos, their pink color comes from carotenoid pigments in their crustacean prey. Nearly hunted to extinction for their plumes in the 19th century, they have recovered substantially.
