Sandhill Crane

The sandhill crane is a large crane of North America and extreme north-eastern Siberia. Adults are grey overall, and in breeding plumage, particularly in migratory populations, look nearly ochre because of staining and wear. They have red foreheads, white cheeks and long, dark, pointed bills. Males average 4.57kg and females 4.02kg, and the wingspan is about 200cm (Wikipedia, general species account).

Females lay one to three (usually two) oval, dull brown eggs with reddish markings. The central Platte River Valley in Nebraska is the most important stopover for the lesser sandhill crane, with up to 450,000 birds migrating through annually. The birds give a loud, trumpeting call that carries a long distance. The source does not describe its status in China (Wikipedia, general species account).
