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.
Northern Cardinal
The northern cardinal is the state bird of seven US states, more than any other species. Unlike many songbirds, both males and females sing, often in duets. Cardinals do not migrate and their brilliant red plumage against winter snow makes them a favorite among backyard birdwatchers.
