Song & Call Comparison
흰머리수리
High-pitched, chattering whistle: a rapid 'kleek-kik-ik-ik-ik'. Surprisingly weak and thin for such a large raptor. Also gives a lower 'kwit-kwit' call near the nest.
Shoebill
Largely silent; produces mechanical bill-clattering 'clap-clap-clap' when greeting at the nest — similar to White Stork. Also gives low croaking grunts. Rarely calls in the wild.

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.
Shoebill
The shoebill is one of the most sought-after birds for birdwatchers visiting Africa, prized for its prehistoric appearance and massive bill. It can stand motionless for hours before collapsing forward to seize prey in its enormous bill. Despite standing over a meter tall, shoebills weigh relatively little due to their hollow bones.
