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.
Great Cormorant
The great cormorant is one of the most widespread seabirds in the world. Unlike most waterbirds, cormorants lack fully waterproof plumage, leading to the iconic pose of standing with wings spread open to dry. In Asia, cormorants have been used by fishermen to catch fish for over a thousand years.
