This ibis lives in western Madagascar and on Aldabra Atoll in the Seychelles. Its pale blue-white eye is distinctive, and it probes tidal mud for crustaceans and other prey.
The body is mostly white, while the wing tips, bare head and neck, and legs are black. It has a narrow downcurved bill and a light blue or white iris.
It pushes its bill into tidal mud to the base while searching for crustaceans and other invertebrates. It may breed near the coast in colonies with herons.
It often forages alone. Alongside crustaceans and other invertebrates, it occasionally eats frogs, reptiles, and birds.
It builds a nest of twigs in a tree fork about 3 m above the water.
It is generally resident, remaining in the same region.
