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.
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.
