The white-headed duck (Oxyura leucocephala) is a small diving duck some 45 cm (18 in) long. The male has a white head with black crown, a blue bill, and reddish-grey plumage. The female has a dark bill and rather duller colouring. Its breeding habitat is lakes with open water and dense vegetation at the margin.
The white-faced whistling duck (Dendrocygna viduata) is a whistling duck that breeds in sub-Saharan Africa and much of South America. This species is gregarious, and at favoured sites, the flocks of a thousand or more birds arriving at dawn are an impressive sight. As the name implies, these are noisy birds with a clear three-note whistling call.

Hardheads are smaller than most ducks, with body length typically between 42 – 59 cm.Both sexes are similar in size, ranging from 525 – 1100 g with wingspans of 65 – 70 cm. [4] Both male and female are a fairly uniform chocolate-brown above, with rufous flanks and white undersides (which are often not visible if the duck is in the water).
The black-headed duck is the most basal living member of its subfamily, and it lacks the stiff tail and swollen bill of its relatives. Overall much resembling a fairly typical diving duck, [5] its plumage and other peculiarities indicate it may not be a very close relative of the other stiff-tailed ducks, but rather the product of convergent evolution from the ancestors of the stiff-tailed ducks.
The male is much larger than the female, and has a large black knob on the bill. Young birds are dull buff below and on the face and neck, with dull brown upperparts, top of the head and eyestripe. [ 4 ] [ 9 ] Knob-billed ducks are generally larger in size when compared to comb ducks, and flanks are usually lighter (light grey, in females ...
Mergellus albellus female (closeup view). The drake smew, with its 'cracked ice' or 'panda' appearance, is unmistakable, and looks very black-and-white in flight.
