About These Birds
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.
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.
