|Comb Duck (Sarkidiornis melanotos)|
|Nova Roma, Goiás, Brazil
The Comb Duck is found in sub-Saharan Africa and tropical Asia as well as in South America.
The South American subspecies S. m. sylvicola may well be a full species and is considered Near threatened whereas the African and Asian nominate subspecies is fairly widespread.
They inhabit swamps, rivers, lakes and grasslands where they feed on seeds and grain with occasional insects. They graze on land and dabble and wade in shallow water.
|The male is unmistakable with a large fleshy knob on the top of his bill. This is lacking in the female as you can see from this photo.
There is an illustration in HBW, Volume 1, Page 590.
