GEESE AND DUCKS – family Anatidae
Most of our ducks are either migratory to some extent or locally nomadic, their movements being dictated by food, rainfall and breeding requirements.
Many show marked plumage differences between the sexes ( sexual dimorphism).
Ducks and gees undergo a flightless 4-8 week period each year when they moult all their flight feathers simultaneously.
The large Spur-winged and Egyptian geese differ from the geese of the northern hemisphere in having longer bills and legs placed well back on the body, which enables them to stand erect and walk without waddling. In addition they show no sexual dimorphism and have whistling voices. In contrast ducks of the genus Anas, often referred to as ‘dabbling ducks’, have widely spaced legs placed centrally on the body, which causes them to stand with the body horizontally and to walk with a waddle. They are further typified by quacking voices.
