Song & Call Comparison
흰머리수리

A liquid, tinkling 'swit-swit-swit' in flight and a melodic twittering song. Flocks produce a bright jingling chorus. Male song is a sweet repetitive warble incorporating the flight call.

About These Birds
흰머리수리
흰머리독수리는 미국의 국조이자 국가 상징입니다. DDT 살충제 사용으로 인해 한때 멸종위기에 처했으나 놀라운 회복을 보여 2007년 멸종위기종 목록에서 제외되었습니다. 이 강력한 맹금류는 어떤 새보다 가장 큰 나무 둥지를 만들며, 어떤 것들은 2톤 이상이 됩니다.
European Goldfinch
방울새는 빨간 얼굴, 노란 날개 띠, 딸랑거리는 노랫소리로 사랑받는 화려한 핀치이다. 엉겅퀴와 같은 식물의 씨앗을 빼내는 뾰족한 부리로 유명하다.
