Africans can be differentiated from Chinese by their heavy bodies and thick necks.
Mature birds have a large, forward-projecting knob above their beaks.
The bill and knob are black in the Brown form and orange in the White African. Africans are the leanest of the heavy breeds and are popular for this reason, as well as for their stately looks. An adult gander and goose should weigh in at 20 and 18 pounds, respectively.
