Having been recognized as a family since 1901, the storks form a well-defined group highlighted by several characteristics both behavioural and morphologic: long legs with the tibiotarsus not covered by feathers; relatively short feet and with small interdigital membranes; 12 primary remiges; 12 secondary remiges; bare parts of the head; oil gland for the feathers, pectoral muscles associated to flying high altitudes; strong beak; feathering predominantly black and white; the young have two layers of fuzz; air sacs under the skin of the neck; loss of the filoplume; similar social behaviours; uro-hydrosis (behaviour of thermal regulation through defecating on the feet) (HANCOCK; KUSHLAN; KAHL, 1992).
