Field notes

  • Females possess a distinctive white face and crown, whereas males have a uniform ash-grey head.
  • Unlike most waterfowl, they frequently nest in abandoned aardvark burrows located far from water.
  • During the post-breeding season, thousands congregate at specific deep-water sites for a synchronous flightless moulting period.
  • They are highly territorial and aggressive, often chasing other waterfowl away from their chosen nesting and feeding sites.
  • Their diet is primarily vegetarian, consisting of agricultural grain, succulent leaves, and various aquatic plants.
Habitat
Shallow freshwater dams, salt pans, and open grassy areas near permanent water sources.
Range
Endemic to Southern Africa, specifically South Africa, Namibia, Lesotho, and parts of Botswana.
