The Sacred Ibis (Threskiornis aethiopicus), is a species of wading bird of the ibis family, Threskiornithidae. The Sacred Ibis breeds in sub-Saharan Africa, southeast Iraq and formerly Egypt. In Egypt it was often mummified as a symbol of the god Thoth. The species has also been introduced into France, Italy, Spain, Australia, and the United States in southern Florida.
Adult individuals are about 27 inches long with all-white body plumage apart from dark plumes on the rump. The bald head and neck, thick curved bill and legs are black. The white wings show a black rear border in flight. Sexes are similar, but the young have dirty white plumage, a smaller bill and some feathering on the neck. This bird is usually silent, but occasionally makes some croaking noises.
The Sacred Ibis occurs in marshy wetlands and mud flats, both inland and on the coast. It will also visit cultivation and rubbish dumps. It feeds on various fish, frogs and other water creatures, as well as insects. The bird nests in tree colonies, often with other large wading birds such as herons. It builds a stick nest often in a Baobab and lays 2-3 eggs.
The introduced and rapidly growing populations in southern Europe are seen as a potential problem, since these large predators can devastate breeding colonies of species such as terns. They also compete successfully for nest sites with Cattle and Little Egrets. The adaptable Ibises supplement their diet by feeding at rubbish tips, which helps them to survive the winter in these temperate regions.
