About These Birds
Blue Jay
어치는 화려한 깃털과 큰 울음소리로 알려진 까마귀과의 대담하고 지능적인 구성원입니다. 가을마다 수천 개의 도토리를 저장하기 때문에 참나무 나무의 중요한 산포자입니다. 복잡한 사회 행동으로 먹이통에서 다른 새들을 겁주기 위해 매의 울음소리를 흉내 내기도 합니다.
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.
