There are two subspecies of Southern Pochard, one from South America
(N. e. erythrophthalma) and one from southern/eastern Africa (N. e. brunnea).
The latter, also called the (South) African Pochard, is shown on this page.
The male, above, is dark brown with red eyes and a blue bill tipped with black.
The female, above, has a scaup-like white patch at the base of her bill and white cheek patches on her face.
Since the male doesn't have an eclipse plumage but has the same plumage all year,
with a bright red eye, the birds above are all females, showing the regular brown eye and, when catching
the sunlight, a dark red eye.
