About Radjah radjah (Garnot & R.Lesson, 1828)
This species, Radjah radjah, has both males and females that are mostly white, with dark wing-tips and a distinct dark feather collar. When seen from above with wings outstretched or during flight, green bands can be seen on the upper surfaces of their wings. For communication, females produce a harsh rattle, while males make a breathy, "sore-throat" whistle. Radjah shelduck lives in mangrove forests and coastlines of New Guinea (covering West Papua and Papua New Guinea), Australia, and some islands of the Moluccas in eastern Indonesia. In Australia, its main range runs along coastal tropical northern Australia, stretching south to central Queensland, west through the upper regions of the Northern Territory (including Kakadu National Park) to the Kimberley region in Western Australia. Radjah shelduck is classified as a protected bird across all Australian states, with penalties for harming or disturbing individuals of the species. This species prefers the salty waters of mangrove flats and paperbark tree swamps, but during the wet season it will travel inland to visit a wide variety of brackish and freshwater swamps, lagoons, lakes, estuaries, river deltas, and billabongs.
