Habitat Comparison
Demoiselle Crane
Dry grasslands, savannas, and semi-desert. Nests on the ground in open country, often near water. Winters in agricultural fields.
Northern Fulmar
Open ocean and sea cliffs. Breeds on cliff ledges and grassy slopes on northern coastlines. Pelagic outside breeding season.
Song & Call Comparison
Demoiselle Crane
A high-pitched, bugling 'karr-r-r' in flight. Also gives softer clucking and purring contact calls. Migrating flocks produce a continuous musical babbling audible from great distance.
Northern Fulmar
A nasal, cackling 'kak-kak-kak-kak' or grunting 'uh-uh-uh' at the nest and colony. Less melodic than petrels. In flight gives occasional single nasal calls.

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 Fulmar
The northern fulmar is a long-lived seabird that can survive over 40 years. It defends its nest by projectile-vomiting a foul-smelling stomach oil at intruders, which can mat the feathers of predators and cause fatal loss of waterproofing. Fulmars have expanded their breeding range dramatically southward over the past two centuries.
