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.
Eurasian Wren
Dense undergrowth in woodlands, gardens, hedgerows, and rocky areas. Prefers tangled vegetation close to the ground.
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.
Eurasian Wren
Extraordinarily loud for its tiny size: a rapid, powerful stream of trills, buzzes, and churring phrases. One of Europe's loudest songs by volume relative to body weight.
Geographic Range & Migration
Demoiselle Crane
Central Eurasia from the Black Sea to Mongolia and northeastern China. Winters in India and sub-Saharan Africa.
Eurasian Wren
Eurasia from Iceland and western Europe to Japan. The only wren species found outside the Americas.

About These Birds
Demoiselle Crane
The demoiselle crane is the smallest crane species but undertakes one of the most grueling migrations, crossing the Himalayas at altitudes over 8,000 meters to reach wintering grounds in India. Named for its elegant appearance by Marie Antoinette, it is the second most abundant crane species in the world.
Eurasian Wren
ヨーロッパ最小クラスの鳥の一つで、体の大きさに不釣り合いな大きな声で鳴く。民話では鳥の王様とされる。
