About These Birds
Barn Swallow
제비는 세계에서 가장 넓게 분포하는 제비류이며, 어떤 참새목 조류보다 가장 긴 이동을 합니다. 북반구 전역에서 봄의 도래를 알리며, 고대 그리스에서 현대 시에 이르기까지 문화적 참고가 되고 있습니다. 제비는 둥지를 위해 인공 구조물에 거의 완전히 의존하게 되었습니다.
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.
