The Woolly-necked Stork is a broad winged soaring bird, which relies on moving between thermals of hot air for sustained long distance flight. Like all storks, it flies with its neck outstretched. It is all black except for the woolly white neck and white lower belly. The upperparts are glossed dark green, and the breast and belly have a purple hue. Juvenile birds are duller versions of the adult. The Woolly-necked Stork walks slowly and steadily on the ground seeking its prey, which like that of most of its relatives, consists of frogs, lizards and large insects. African birds are attracted to bush fires.
