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.
Eastern Bluebird
동부파랑새는 북미에서 행복의 상징으로 사랑받는 새이다. 한때 농약과 집 짓기 경쟁으로 급감했지만, 둥지 박스 설치 운동 덕분에 개체군이 크게 회복되었다. 수컷은 짙은 파란 윗면과 녹슨 붉은 가슴을 자랑한다.
