White faced ducks (Dendrocygna viduata - also called White-faced Whistling duck) painted from a photograph I took at Sun City in North-West Province (South Africa) some years ago. They vocalize frequently with distinctive high-pitched, multi-syllabic whistles which sound very un-duck-like and their sweet "tweeeeet" belies their belligerent and boisterous nature as they constantly bicker and fight among one another, they're never still for a moment! Just getting a couple of photos was quite a job as they constantly swim and fly to and fro over the pond.
The lovely pond is situated right against the dining room windows of the Cascades Hotel, which offers gorgeous views over the gardens.
The adult males have the front half of their head and throat white and the rest of their head and neck are black with white patches on the underside of the neck the lower neck and wing shoulders are chestnut; their flanks are barred black on white the rest of the underparts, underside of wings, the rump and tail are black.
