The Blue Crane (Grus paradisea), also known as the Stanley crane and the paradise crane, is the national bird of South Africa. It is a tall, ground-dwelling bird, but is fairly small by the standards of the crane family. This crane is pale blue-gray in color becoming darker on the upper head, neck and nape. From the crown to the lores, the plumage is distinctly lighter, sometimes whitish. The bill is ochre to greyish, with a pink tinge. The long wingtip feathers which trail to the ground. The primaries are black to slate grey, with dark coverts and blackish on the secondaries. Unlike most cranes, it has a relatively large head and a proportionately thin neck.
Blue cranes are birds of the dry grassy uplands, usually the pastured grasses of hills, valleys, and plains with a few scattered trees.
Of the 15 species of crane, the blue crane has the most restricted distribution of all. Even species with lower population numbers now (such as Siberian or whooping cranes) are found over a considerable range in their migratory movements. The blue crane is migratory, primarily altitudinal, but details are little known.
The blue crane is partially social, less so during the breeding season. There is a strict hierarchy in groups, with the larger adult males being dominant.
Blue cranes feed from the ground and appear to rarely feed near wetland areas. Most of their diet is comprised by grasses and sedges, with many types fed on based on their proximity to the nests. They are also regularly insectivorous, feeding on numerous, sizeable insects such as grasshoppers. Small animals such as crabs, snails, frogs, small lizards and snakes may supplement the diet, with such protein-rich food often being broken down and fed to the young.
The South African government has stepped up legal protection for the blue crane. Other conservation measures are focusing on research, habitat management, education, and recruiting the help of private landowners.
The blue crane is culturally significant to the Xhosa people, who call it indwe. Traditionally, when a man distinguished himself in battle or otherwise, he was often decorated by a chief with blue crane feathers in a ceremony called ukundzabela. Men so honored, who would wear the feathers sticking out of their hair, were known as men of ugaba (trouble)—the implication being that if trouble arose, they would reinstate peace and order.
