About These Birds
Demoiselle Crane
쇠두루미는 가장 작은 두루미 종이지만 가장 혹독한 이동을 하며, 해발 8,000m 이상의 히말라야를 넘어 인도의 월동지로 향한다. 우아한 외모로 마리 앙투아네트에게 명명되었으며 세계에서 두 번째로 풍부한 두루미 종이다.
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.
