Size Comparison
Habitat Comparison
Demoiselle Crane
Dry grasslands, savannas, and semi-desert. Nests on the ground in open country, often near water. Winters in agricultural fields.
Snowy Owl
Arctic tundra for breeding. Winters in open habitats resembling tundra, including prairies, airports, shorelines, and agricultural fields.
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.
Snowy Owl
Male gives a deep booming hoot 'hooooo' and a rising 'hoo-hoo' series. Also barks sharply when alarmed. Quieter than many owls; silent during long Arctic winter hunts.
Geographic Range & Migration
Demoiselle Crane
Central Eurasia from the Black Sea to Mongolia and northeastern China. Winters in India and sub-Saharan Africa.
Snowy Owl
Circumpolar Arctic for breeding. Irruptive winter movements bring birds south to the northern United States, Europe, and Asia.

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.
Snowy Owl
The snowy owl is the heaviest North American owl and one of the most charismatic Arctic birds. Unlike most owls, it is largely diurnal, necessitated by the continuous daylight of Arctic summers. Snowy owl irruptions — periodic mass southward movements — are tied to lemming population cycles.
