Siberian crane (Grus leucogeranus)

Appearance and behaviour

Adult birds are predominantly white with contrasting black primary feathers visible in flight; juveniles show dusky markings. They are long‑legged and long‑necked, with a loud, tremulous call typical of cranes. Siberian cranes form long‑term pair bonds during the breeding season and build shallow nests on tundra or marsh islands. Their social structure, courtship dances and vocalizations align them with other members of the crane family.

Range and migration

Breeding takes place on arctic and subarctic wetlands in Siberia. The species is traditionally divided into three main groups with separate flyways: the eastern group migrates from eastern Siberia to winter in parts of China, the central group historically traveled from western Siberia toward wintering grounds in India, and a western group used wetlands farther west, including sites in Iran. These long-distance migrations rely on a chain of stopover wetlands along each route.

Habitat and diet

Siberian cranes depend on shallow freshwater wetlands — tundra pools at breeding sites and lakes, marshes and floodplains at stopovers and wintering areas. Their diet includes aquatic plants, roots and tubers, seeds, and small aquatic animals; they feed by probing and gleaning in soft substrates.

Threats and conservation

• Wetland loss and degradation from drainage, agricultural conversion and water diversion.
• Illegal hunting and disturbance along migration corridors and at wintering sites.
• Collisions with power lines and reduced availability of safe stopover habitats.

Conservation actions combine habitat protection and restoration, legal protection, captive breeding and reintroduction, satellite tracking and international cooperation to safeguard flyways. Many initiatives involve local communities and cross‑border agreements to maintain the chain of wetlands cranes require.

Notable facts

The Siberian crane is an emblematic wetland species: its plight highlights the broader problem of wetland loss across Eurasia. While some captive and reintroduction programs have had localized success, recovery depends on protecting key breeding, staging and wintering sites and reducing human threats along its migration routes.
