About These Birds
Common Crane
Common Crane (Grus grus) is a large 100–130 cm crane of Eurasia. Grey with black and white head pattern; bare red crown patch; drooping bushy tail plumes. Wingspan to 240 cm. Breeds from Scandinavia east to Siberia; winters in Spain, Africa, India, and China. Forms enormous migratory flocks. Feeds on grain, roots, and invertebrates.

Their elaborate unison call and dancing displays have inspired art and folklore for millennia. The resident population on Hokkaido, Japan, recovered from about 33 birds in 1952 to over 1,800 today.
