Storks are large, long-legged, long-necked wading birds with long, stout bills. They belong to the family Ciconiidae, and make up the order Ciconiiformes /sɪˈkoʊni.ɪfɔːrmiːz/. Ciconiiformes previously included a number of other families, such as herons and ibises, but those families have been moved to other orders.
