Field notes

  • This species exhibits an unusual disjunct distribution, occurring naturally across both sub-Saharan Africa and South America.
  • Unlike most ducks, they are highly social and engage in frequent mutual preening (allopreening) to reinforce social bonds.
  • They are primarily nocturnal or crepuscular feeders, often flying to foraging grounds in large flocks at dusk.
  • Their long legs and upright posture are characteristic of the whistling-duck lineage, which is taxonomically intermediate between geese and 'true' ducks.
  • During the dry season, they can congregate in massive colonial flocks that sometimes number in the tens of thousands.
Habitat
Freshwater wetlands, including lakes, rivers, marshes, and flooded grasslands.
Range
Sub-Saharan Africa, South America, and Madagascar.
