The Radjah Shelduck is a large white duck with brown back and wing tips, and a rusty band across the breast (narrower breast band in females). It has pink legs and beak.
Radjah Shelducks occupy terrestrial wetlands, estuaries and the littoral zone of monsoonal regions. It nests in tree hollows in the wet season, forming flocks near the coast during the dry season. It uses its beak as a filter to feed on small invertebrates and a few seeds, taken from shallow wetland edges. Although not the most common duck in the region, it nonetheless remains fairly common, particularly in and around local wetlands.
