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.
그리폰독수리
The griffon vulture is one of Europe's largest flying birds and a crucial scavenger in Mediterranean ecosystems. These social birds nest in large cliff colonies and can soar for hours using thermals without flapping. Vulture populations faced a crisis from the veterinary drug diclofenac, which proved fatal when consumed through contaminated carcasses.
