The body of the black stork is 96cm long, and its head and neck, upper chest, and back are glossy black. The belly is white, and the bill, legs, and sides of the eyes are red. The young bird has an overall blurred color mixed with brown. This bird lives in a rice field, the riverside, or a small valley, alone or as part of a couple. It builds a nest on top of a high tree or on the twig of a rock cliff and lays 3~5 white eggs.
