Comb Duck
Sarkidiornis melanotos
The Comb Duck (Sarkidiornis melanotos) is also known as the Knob-billed Duck. The species is widespread over much of southern Africa but also occurs in parts of South America and India. Some taxonomists regard these geographically separated populations as distinct species, but treat them together. The shots here were taken near Malelane, Mpumalanga Province, South Africa in January, 2006 with a Canon EOS 1D Mark II & EF 500mm F/4L IS lens. Only the male shows the unusual structure on the bill. Note the shots of the smaller female.
