The Ruddy shelduck (Tadorna ferruginea) is a distinctive waterfowl that has a loud honking call. The ruddy shelduck mostly inhabits inland water-bodies and forms a lonf lasting pair bond. In central and eastern Asia, populations of this species are steady or rising, but in Europe, they are generally in decline.
The male Ruddy shelduck 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. The female is similar but has a rather pale, whitish head and neck and lacks the black collar, and in both sexes, the coloring is variable and fades as the feathers age. The birds molt at the end of the breeding season and the male loses the black collar, but a further partial molt between December and April restores it. Juveniles are similar to the female but are a darker shade of brown.
