The wing coverts are white, the primary remiges black, and the secondaries black with a strong green iridescent reflection in good light (only showing in flight). The outer tertial feather is orange-brown, with the inner tertials white. The underwings are white, except for the flight feathers, which are black.

Ruddy Shelduck
Tadorna ferruginea
The ruddy shelduck grows to a length of 58 to 70 cm (23 to 28 in) and has a 110–135 cm (43–53 in) wingspan. The male has orange-brown body plumage and a paler, orange-brown head and neck, separated from the body by a narrow black collar. The rump, flight feathers, tail-coverts and tail feathers are black and there are iridescent green speculum feathers on the inner surfaces of the wings. Both upper and lower wing-coverts are white, this feature being particularly noticeable in flight but hardly visible when the bird is at rest. The bill is black and the legs are dark grey.
