About These Birds
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.
オジロワシ
The white-tailed eagle is Europe's largest eagle and the fourth-largest eagle in the world. Once extinct in Britain, it has been successfully reintroduced to Scotland and Ireland through conservation programs. These powerful raptors can live over 25 years and form lifelong pair bonds.
