Distribution and habitat

Occurs from southern DRC through Uganda, Tanzania, Zambia, Angola and Malawi to South Africa. In southern Africa, it is generally uncommon in patches of Zimbabwe, central and southern Mozambique, eastern South Africa and central Namibia, while more abundant in northern Botswana and the Caprivi Strip (Namibia). It generally prefers flooded grassland and the shore of permanent water bodies (fringed by reedbeds).

Predators and parasites

Movements and migrations

Resident and sedentary on the Okavango Delta, while it is thought to be a breeding migrant to Zimbabwe in mid to late summer. It also breeds on the Nyl River flood plain, Limpopo Province in the period from December-May.

Food 

It mainly eats fish, amphibians, insects and worms, doing most of its foraging by standing still or slowly moving through shallow water, stabbing any prey that comes too close.

Breeding

  • Monogamous, solitary or colonial nester, sometimes breeding in groups of 2-4 pairs.
  • The nest is a shallow platform of reeds and twigs, lined with grass or flowers. It is typically placed in a well-foliaged tree or bush, or alternatively in a Phragmites reedbed.
  • Egg-laying season is nearly year-round.
  • It lays 1-4 eggs, which are incubated by both sexes for roughly 21 days.
  • The chicks are able to fly at about 24 days old, and can fly strongly about week later.

Threats

Not threatened.
