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.
Roseate Spoonbill
The roseate spoonbill is the only spoonbill species in the Americas and one of the most striking wading birds in the Western Hemisphere. Like flamingos, their pink color comes from carotenoid pigments in their crustacean prey. Nearly hunted to extinction for their plumes in the 19th century, they have recovered substantially.
