The Hottentot teal is uncommon to locally common, preferring to live in permanent, shallow wetlands with tall, emergent vegetation. Its diet varies greatly with different regions, although it usually it eats more animals than it does plant matter. The pair bond barely lasts for the duration of the incubation period, after which the female does all the work. The nest is a bowl in the ground, filled with grass and leaves, lined with down feathers. It lays 5-12 eggs, which are incubated solely by the female, for 25-27 days. The chicks stay in thick reed beds, making them very hard to spot. They usually fledge at 60-65 days old.

Distribution and habitat

Occurs from Ethiopia south, through southern DRC, Tanzania, Zambia and Angola to southern Africa. Within southern Africa it is locally common, occupying Namibia, northern and eastern Botswana, Zimbabwe, southern Mozambique and eastern South Afirica. It generally prefers permanent, shallow wetlands with bulrushes (Typha), reeds (Phragmites) or other tall, emergent vegetation.

Distribution of Hottentot teal in southern Africa, based on statistical smoothing of the records from first SA Bird Atlas Project (© Animal Demography unit, University of Cape Town; smoothing by Birgit Erni and Francesca Little). Colours range from dark blue (most common) through to yellow (least common). See here for the latest distribution from the SABAP2.  

Movements

Thought to be a sedentary bird, rarely going on > 300 km journeys. The longest recorded flight is 694 km, although it can probably fly a lot further than that. It sometimes travels to the Okavango delta in the wet season.

Parasites

  • Clostridium botulinum (Botulism)
  • Freyana largifolia (Feather mite)

Food

It tends to eat more animals than it does seeds, although its diet varies with different regions and times of year. It usually gathers into groups of 10 or more, feeding by submerging its head in water while swimming or by up-ending.

Breeding

  • Monogamous, territorial solitary nester. Interestingly, the pair bond barely lasts beyond incubation, with the male having almost no role in incubation and care of chicks.
  • The female builds the nest, which is a deep bowl in the ground, filled with grass and leaves, often lined with down. It is usually placed in emergent vegetation near water.
  • Laying dates vary with different regions, but usually in February-May.
  • It lays 5-12 eggs, in successive days.
  • Incubation is done solely by the female, for 25-27 days. She will sometimes leave the nest, to join the male in feeding and preening.
  • The chicks are kept hidden in thick reedbeds, which makes them difficult to see. They fledge when they are about 60-65 days old.

Threats

  • Not threatened.
