About These Birds
Barn Owl
헛간올빼미는 어떤 올빼미보다 가장 비대칭적인 귀를 가지고 있어, 동물계에서 가장 정밀한 청각 위치 파악 능력을 지닙니다. 소리만으로 완전한 어둠 속에서 먹이를 잡을 수 있습니다. 헛간올빼미의 독특한 하트 모양 얼굴은 포물면 접시처럼 작용하여 소리를 어긋난 귀로 집중시킵니다.
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.
