There are 2 kinds of Whistling Ducks in Australia. And as I promised Theresa from The Run*A*Round Ranch Report , here they are.
The Wandering Whistling-Duck.
"The Wandering Whistling-Duck is a large duck with rich red-brown plumage overall, with a paler face, front of neck and upper breast. There is a dark stripe on the crown of head, nape and back of neck. The bill and legs are dark. There are elongated flank plumes, which are off-white with chestnut edges. In flight, the dark underwings, cinnamon and chestnut underbody, white undertail and trailing dark legs are seen." - Birds In Backyards
And the Plumed Whistling-Duck; which is quite different in colour and appearance
"The Plumed Whistling-Duck... is a tall, long necked duck, with very prominent long lanceolate off-white plumes edged in black along the flanks. The face and foreneck are light, the crown and hind neck are pale brown and the brown feathers of the upper back are edged buff. The breast is pale chestnut, finely barred in black. The bill is mottled pink and grey and the legs and feet are pink." - Birds In Backyards
You can see the distinct differences in colour, markings and build in the image below...
