The demoiselle crane (Grus virgo) is a species of crane found in central Eurosiberia, ranging from the Black Sea to Mongolia and North Eastern China. There is also a small breeding population in Turkey. These cranes are migratory birds. Birds from western Eurasia will spend the winter in Africa while the birds from Asia, Mongolia and China will spend the winter in the Indian subcontinent. The bird is symbolically significant in the culture of India, where it is known as Koonj or Kurjaa.
The demoiselle is 85–100 cm long, 76 cm tall and has a 155–180 cm wingspan. It is the smallest species of crane. The demoiselle crane is slightly smaller than the common crane but has similar plumage. It has a long white neck stripe and the black on the foreneck extends down over the chest in a plume.
It has a loud trumpeting call, higher-pitched than the common crane. Like other cranes it has a dancing display, more balletic than the common crane, with less leaping.
The demoiselle was so named by Queen Marie Antoinette, for its delicate and maiden-like appearance.
