African Black Duck

The African black duck (Anas sparsa) is a species of duck of the genus Anas. It is genetically closest to the mallard group,[2] but shows some peculiarities in its behavior[3] and (as far as they can be discerned) plumage; it is accordingly placed in the subgenus Melananas pending further research. https://en.wikipedia.org/wiki/African_black_duck
