Storks have large and heavy bills. Their nests are also very large and used year after year. They are mute, but clack their bills as a means of communication, especially at or near the nest. They eat insects, worms, fish, and small mammals. They are related to egrets, herons, ibises, and spoonbills, but not to flamingos.
The southern ground hornbill is characterized by black coloration and vivid red patches of bare skin on the face and throat (yellow in juvenile birds), which are generally believed to keep dust out of the birds eyes while they forage during the dry season. The white tips of the wings (primary feathers) seen in flight are another diagnostic characteristic. The beak is black and straight and presents a casque, more developed in males.
