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.
Peregrine Falcon
매는 세계에서 가장 빠른 동물로, 먹이를 향해 급강하할 때 시속 320km 이상의 속도를 낼 수 있습니다. 남극 대륙을 제외한 전 세계에 분포하며 도시 고층 건물에서도 번식합니다. DDT 사용으로 20세기 중반 크게 줄었다가 현재 회복되었습니다.
