Northern Gannet
Loud, harsh 'urrah-urrah' grunting and croaking at breeding colonies on sea stacks. Also gives a softer 'karrr' in flight. Large colonies are extremely noisy during the breeding season.

About These Birds
부채머리독수리
하피수리는 세계에서 가장 강력한 맹금 중 하나로 발톱이 회색곰의 발톱만큼 크다. 멕시코에서 볼리비아와 브라질까지 아메리카 열대우림에 서식하며 나무늘보, 원숭이, 이구아나 등을 사냥한다.
Northern Gannet
The northern gannet is a spectacular plunge-diver, folding its two-meter wingspan into an arrow shape to hit the water at up to 100 km/h. Air sacs under the skin and a reinforced skull protect it from the impact. Bass Rock in Scotland hosts over 150,000 gannets, the largest single colony of any seabird in the world.
