About These Birds
Common Raven
큰까마귀는 가장 지능적인 조류 중 하나로, 도구 사용, 미래 계획, 복잡한 사회적 행동을 보인다. 전반적으로 광택 있는 검은 깃털을 가지며 북반구 전역의 다양한 서식지에 서식한다.
Red-crowned Crane
The red-crowned crane is one of the rarest crane species and a potent symbol of longevity and fidelity in East Asian culture. Their elaborate unison call and dancing displays have inspired art and folklore for millennia. The resident population on Hokkaido, Japan, recovered from about 33 birds in 1952 to over 1,800 today.
