About These Birds
Grey Crowned Crane
Grey Crowned Crane (Balearica regulorum) is a tall 100–110 cm crane of eastern and southern African grasslands and wetlands. Grey body, white and red facial wattles, and a distinctive golden bristle crown. Inhabits open grassland, cultivated land, and wetland margins from Kenya south to South Africa. Roosts in trees.
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.
