Distribution and habitat
Occurs from Ethiopia south through
Uganda, Kenya, southern DRC, Tanzania, eastern Angola and Zambia to southern
Africa. Here it is uncommon to locally common in the Caprivi Strip (Namibia),
northern Botswana, Zimbabwe, southern Mozambique and patches of South Africa,
largely excluding the Northern Cape, Free State and Eastern Cape. It generally
prefers reedbeds and other dense vegetation along the edges of swamps, streams
and marshes, sometimes moving to paddy fields and seasonally wet sugar cane
fields next to marshes.

Predators and parasites
- Predators
-
of adults
-
of chicks and eggs
Movements and migrations
Resident and largely
sedentary, although it may make local movements in response to
environmental conditions.
Food
Mainly eats insects, earthworms,
spiders, small frogs, small fish and plant matter such as seeds, doing most of
its foraging in mud or shallow water along the edges of reedbeds, probing in
search of prey.
Breeding
-
Monogamous, solitary nester, establishing a territory at the
onset of the breeding season in July and June by fighting with other pairs.
-
The nest is a shallow saucer of leaves, sedge stems,
Bulrushes (Typha capensis) and grasses, typically concealed within or
between grass or sedge tufts.
-
Egg-laying season is from July-May, peaking from
September-February.
-
It lays 2-6 eggs, which are incubated by both sexes for
about 20 days.
-
The chicks leave the nest soon after hatching, becoming
fully independent when they fledge at 42-56 days old.
Threats
Not threatened.
