The Demoiselle Crane is the smallest crane. It is blue-gray in color, with black eyes, sides of the head, throat and front neck. There is a white ear tuft behind the eyes that is very eye-catching. The black feathers on the front neck are extended and hang on the chest. The feet are black, and the wing tips are black when flying. The black feathers on the front neck are extended and hang on the chest. The feet are black, and the wing tips are black when flying. When flying, it forms a "V" formation with the neck straight. The call is like a horn, similar to that of the gray crane, but it is sharper and less undulating.
Except for the breeding season, they usually move in families or small groups, and sometimes they move alone. They often move in shallow water near the water or on the higher ground near the water on the sheep grass meadow. They are timid and alert, good at running, often stay away from humans, and are unwilling to get together with other cranes.
The breeding season is from April to June, with one male and one female. When they first migrate, they often move in small groups, and then gradually disperse into pairs and occupy nesting areas. They usually do not build nests, but lay eggs directly on the exposed and dry saline-alkali land in the sheep grass meadow, with sheep grass, reeds, Artemisia capillaris and other plants growing around them.
