The Siberian Crane also known as the Siberian White Crane or the Snow Crane, is a bird of the family Gruidae, the cranes. They are distinctive among the cranes, adults are nearly all snowy white, except for their black primary feathers that are visible in flight and a naked red face, with two breeding populations in the Arctic tundra of western and eastern Russia. They eastern populations migrate during winter to China while the western population winters in Iran and formerly, in India. Among the cranes, they make the longest distance migrations. Their populations, particularly those in the western range have declined drastically in the 20th century due to hunting along their migration routes and habitat degradation. The world population was estimated in 2010 at about 3200 birds, mostly belonging to the eastern population with about 95% of them wintering in the Poyang lake basin in China, a habitat that may be altered by the Three Gorges Dam.Height is about  5 ft tall and they weigh about 13 pounds All cranes are omnivorous. Siberian Cranes eat a wide variety of food items. On the breeding grounds in spring, they eat cranberries, rodents, fish and insects.
The traditional migratory and wintering habitats of this species are under constant pressure from the demands of the growing human population.
