About These Birds
Black Swan
검은 백조는 한때 모든 백조가 흰색이라고 믿었던 유럽인들에게 불가능하다고 여겨졌으며, 귀납적 추론 실패의 유명한 철학적 예가 됩니다. 서부 오스트레일리아의 주 새입니다. 검은 백조는 평생 짝 유대를 형성하며 양 부모가 포란과 새끼 양육을 공유합니다.
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.
