FUN FACTS

1. Demoiselles will often fake a wing injury to distract predators from their nests.
2. The mating dance of crane is spectacular. The birds walk stiffly around each other with quick steps, wings half spread, alternately leaping high in the air. During this display, the cranes bow deeply and stretch. Next, the cranes pick up sticks or pieces of grass, throw them in the air, and stab at them with their beak as they come down. Both sexes, mature and immature, take part in the dances.
3. Cranes form lifelong monogamous pair bonds.
4. During migration cranes fly with their head and neck straight and their feet and legs straight behind them. They are able to reach heights of 4,875-7,925 m (16,000-26,000 ft). Their migration is so long and hard that many die from fatigue, hunger, or predation from birds of prey.
5. Demoiselle cranes are the smallest of all crane species and the second most abundant of the world's cranes (only the sandhill crane is more numerous).

ECOLOGY AND CONSERVATION

Demoiselle cranes are protected by a few cultures in many parts of its range. In several Islamic regions, the birds are held in high regard because the Koran mentions them. In Mongolia and parts of India they are considered lucky birds and are protected by local people.

Demoiselle cranes are not endangered, however, their range and habitat has slowly been destroyed. Scientists record the last sighted breeding in Tunisia and Morocco was in the 1930s.

Of 15 species of cranes, 7 are endangered or threatened due to breeding habitat destruction.
