The African pygmy goose (Nettapus auritus) is a perching duck from sub-Saharan Africa. It is the smallest of Africa's wildfowl, and one of the smallest in the world.
Though pygmy geese have beaks like those of geese, they are more related to the dabbling ducks and other species called 'ducks'.
It is one of the species to which the Agreement on the Conservation of African-Eurasian Migratory Waterbirds (AEWA) applies.
The African pygmy goose is one of the smallest of the perching ducks, and it has the average weight of about 285 grams (10.1 oz) for males and 260 grams (9.2 oz) for females and wingspans between 142 millimetres (5.6 in) and 165 millimetres (6.5 in).
They have a short bill which extends up the forehead so they superficially resemble geese.
