About These Birds
Sandhill Crane
Sandhill Crane (Grus canadensis) is a large 80–120 cm grey North American crane with a bare red crown and bushy tail plumes. Wingspan to 185 cm. Breeds across Arctic Canada, Alaska, and northern USA; migrates in vast flocks along central flyways; winters in the southern USA and Mexico.
Red-crowned Crane
The red-crowned crane is one of the rarest crane species and a potent symbol of longevity and fidelity in East Asian culture. 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.
